How To: UnRoot Your T-Mobile G1/Get Back to Cupcake
Posted on: July 5, 2009
Posted in: Android How To's, HTC G1/Dream, How To's, Video
So you need to send in your phone for warranty purposes? Or maybe you’ve been loading too many ROMs and would like to start fresh? Maybe you just hate being different and just want to be like everyone else, damn it!
Here is how to UNRoot the G1 and get back to the stock G1 firmware.
I. Downgrade the SPL
!!!IF YOU NEVER LOADED A CUSTOM SPL, OR HAVE NO CLUE WHAT THIS IS, THEN SKIP IT AND GOTO THE DREAIMG.NBH SECTION).
1. Download the Original SPL:
Original SPL
2. Rename the Original SPL to Update.zip and place it (now named update.zip) on the SD card (not in any folder).
3. Turn off the phone
4. Turn on the phone holding Home and End key till the recovery screen pops up.
5. Hit Alt W to wipe the phone, then hit Alt S to load the update.zip
6. After the update is complete, press Home and Back to reboot.
7. Once the phone reboots to the G1 Logo, turn it off by taking out the battery. Then put the battery back in. *READ THE REPORTED ISSUES FOR A COMMON ISSUE WITH THIS STEP!
II. Load the DreaIMG.nbh File
1. Download the Original DreaIMG.nbh file:
Original DREAIMG.nbh
2. If the file downloaded above downloads as a .Zip file, please unzip it first then put the DreamIMG.nbh file that is inside on the SD card, NOT in any folder. (If you did Section I the phone is off still, take out the memory card, put it in the MicroSD adapter and plug it into your computer to transfer the file over, since your G1 won’t turn on right now if you did Section I above. Otherwise if you did not need to do Section I above, then you can just put it on the SD card normally using the usb cable and the phone).
3. Turn the phone off if it is on.
4. Turn on the phone by holding the Camera button and the End key until the bootloader screen turns on.
5. Hit the End key to start the update. DO NOT INTERUPT THIS PROCESS.
6. Once it is done, hit the trackball to restart the phone. You now are on the stock firmware RC29. You must do the next section to get back to cupcake.
III. Get Back to Cupcake
1. Download the cupcake update from here, then put it on your SD card, rename it to update.zip Turn off your phone and turn it back on by holding down Home and Power to get to recovery mode. In recovery mode (the ! screen) hit Alt L to see text, then hit Alt S to Apply the update.
Reported Issues
Issue: It doesn’t see the Dreaimg.nbh file and goes to the rainbow screen and says Serial 10.
Solution: Your SD card is formatted to FAT instead of FAT32. Follow one of our readers’ instructions to fix (thanks Clemshady!):
“To Jess and any one else who is unable to get past the rainbow screen with serial 10, your SD card is most likely in a FAT format and needs to be formatted to FAT32. I had the same issue.
- Load your SD card in the card reader and connect to PC.
- Make sure you back up everything on your card. a format will erase all data on the card.
- Now open “My Computer” and right click on the drive with the SD card (Warning! Make sure its the correct drive).
- Click on Format and select FAT32 on the file system drop down and click then click Start.
- Once completed, Copy your files back to the SD card and make sure the “Original DREAIMG.nbh” is at the topmost folder of your SD card.
- Return to Step 8 of David’s instruction to complete the un-root process and you are all set!”
Issue: I get an error, failure, or nothing happens when I get to the rainbow screen and try to load Dreaimg.nbh file.
Solution:
The files we had in the links above became corrupt. We have replaced the links as of 08.25.2009 so they should now work.
If you are still having issues; the dreaimg.nbh file is either not on the topmost folder of the SD card OR the file is corrupt or incomplete.
Delete the file off of your SD card and then re download it from our site or on XDA-Developers.com and then put it on the topmost folder of the SD card. You may have to do this multiple times before it finally works. KEEP DOING THIS UNTIL IT WORKS!
Issue: I load the SPL (wipe and apply update.zip) but then when I try to hold camera and power to get to bootloader it brings me to the G1 screen.
Solution: This is because you took out the battery too soon.
1. Put the SPL back on the memory card and rename to update.zip (using an SD Card reader or adapter)
2. Boot into recovery by holding down Home and Power to turn on the phone.
3. At the recovery screen Wipe Data, then Apply Update.zip
4. Once it is done loading hit Reboot and wait for the phone to reboot (it will show a box an arrow and a G1 on the screen for a bit then it will reboot). Wait at the G1 screen for 20 seconds, it should reboot one more time or it should goto the recovery screen again. If you see the recovery screen or are still at the G1 logo after 20 seconds, THEN remove the battery and put it back in and continue with the next step of trying to hold the camera and power button and so on.

Original SPL
Original DREAIMG.nbh where can i get these files it says download these 2 files but you cant from this page
July 5th, 2009 at 5:06 pm
Hello Ben,
I just posted that post lol The files should be up in a second.
July 5th, 2009 at 8:25 pm
thanks i feel like i was the propose for this but will it go to version 1.5?
July 6th, 2009 at 11:00 am
Hey David J,
Ha, no you aren’t a few people wanted to go back so that they could start over with the process so don’t worry.
It will get you to RC29 and then within a few hours your phone should automatically update back to Cupcake.
July 6th, 2009 at 3:00 pm
i have my phone unlock to att. if i do this will it lock back to t-mobile?
July 7th, 2009 at 1:40 pm
Hello Steve,
Too be honest that is a good question, I’m not entirely sure (as I don’t have an unlocked one to try, sorry).
July 8th, 2009 at 12:56 am
so what if i cant get to the recovery screen. i, for some reason, updated from the 2.22 ## radio to an older version and now it will not let me get passed the tmobile G1 boot screen. even when i hold home on start up. the camera button start up doesnt work either. is my phone bricked? im assuming it is………
July 8th, 2009 at 5:46 am
Hey david,
Just to check with you, what is a SPL? Is it the Recovery boot menu?
July 8th, 2009 at 1:07 pm
Hello michael,
Once you load the newest radio you should never load a radio again (not an older one or even the same radio twice). Is that what you did?
If that is the case, no your phone is not bricked. (I have yet to see a phone that cannot be fixed…).
Try the method of taking out the SD card putting it into an SD adapter and into your computer. Then put a custom ROM on their, rename it to update.zip and then put it back into the phone. Hold down Home and Back and when the ! comes up hit Alt and S.
Let me know if this works.
July 8th, 2009 at 1:08 pm
@ steve,
I don’t think it will lock back to tmobile because flashing a ROM doesn’t have anything to do with the process you went through to unlock your phone from the carrier. I say if you have been flashing/testing ROMS this whole time with no problem, all you doing is flashing/testing another one, it just happens to be the original one. What won’t happen for an unlocked phone on ATT’s network is an OTA update so you’ll be stuck at RC29 because you won’t have root access anymore to update it to cupcake. I say leave it rooted.
July 8th, 2009 at 1:15 pm
Hey Az,
An SPL is what loads ROMs. You never actually see an SPL.
The Recovery image is a separate program that runs when you hit home and end to start the phone up. The phone comes with one already installed (the little ! screen) so we use that for more videos, but there are customized ones that allow you to back up your stuff from them, wipe without rebooting, etc. My favorite is Cyanogen’s. But again it is unnecessary, just useful for us ROM junkies, loading and loading new ROMs constantly to test them out etc lol
July 9th, 2009 at 1:32 pm
Im tryin to do this, but it keeps sayin no image found and i dont understand. I did everything right!!
July 9th, 2009 at 3:03 pm

Hey Shaud,
July 9th, 2009 at 5:14 pm
Ok thanks got everything working, insteed of going back to stock, I went downgraded to TheDudeOfLife. So Im ok for now. Thanks
July 10th, 2009 at 4:25 am
Hey Guys, I just found this website and its amazing! Well if someone can please help a newbie in this process. I understand the video but really I don’t understand much about what going on with the g1 scene. I haven’t used the g1 since it was first out and haven’t seen it since. So I’m completely outdated with any news or modifications. Anyway I just got a g1 on craiglist. So far I want to start from scratch, my question is what should I do? what does rooting do? Thanks i hope someone can fully explain to me what going on

Hey David,
Any problems downgrading the SPL, similar to problems associated with downgrading the radio? I loaded Cyanogen’s Recovery, partitioned my SD card in preparation for loading jacHEROski, and realized that I had the engineering SPL and not the hard SPL. When I tried to upgrade to the hard SPL I ran across a boot loop. Then I tried to reflash the hard SPL and ran into a “formatting CACHE” loop in Cyanogen’s Recovery screen. So I tried to reflash thedude’s latest to no avail to I flashed jesusfrekes and I got lucky so I know I’m not bricked. I’m thinking the best way to proceed is to start with a clean slate. If I follow these instructions, is the radio going to be the only thing that will not be stock/original like when I first got the phone? I’ll know I’ll have to re-root etc but I don’t mind all that. Thanks….
July 10th, 2009 at 1:20 pm
Hey David, I can’t seem to flash anything over Cyanogen’s recovery image to get back to the original boot loader (rainbow screen). Even after flashing the original SPL I still get to the Cyanogen’s recovery image. Is there anyway around this? Without the original bootloader (rainbow screen) I am assuming that I cannot flash the original DREAIMG.nbh?!?
July 10th, 2009 at 2:01 pm
Hey Mike,
Thanks! Glad you like the site, much more to come hopefully
Rooting is basically making the phone give you full access to all of its files, folders, permissions, etc. Once you have root access you can alter/customize a lot of things. But from an end user’s standpoint, it allows you to load custom ROMs. A ROM is what contains the Operating System and native applications. Now, very nice developers (on XDA mostly) create custom ROMs that they add a bunch of features into. Once you have root access the phone will allow you to load these custom ROMs. Also there are custom Themes as well that can be loaded etc.
You would want to follow these videos in this order (be careful to follow directions as you could potentially lock up your phone):
How to Root
How to Load a Custom ROM
Do NOT goto the video of Apps2SD or for the Hero ROM until you have loaded a few different ROMs and themes successfully and are feeling pretty confident.
July 10th, 2009 at 2:34 pm
Hey DirectMatrix,
No problems downgrading the SPL (just don’t touch the radio lol).
And yes if you follow the instructions everything will be stock (I’m actually not sure about the Radio cause I think the Dreaimg file has a radio in it… just check after you reboot but loading the bootloader, no big deal either way).
July 10th, 2009 at 2:37 pm
Hey DirectMatrix,
You flashed the original SPL that is in the tutorial, right? The recovery image is not part of the SPL I believe so it shouldn’t get rid of it.
If you got the Original SPL to flash (check by booting into bootloader and see if you get the rainbow or the skateboarding android), then just load the dreaimg file in the rainbow screen and once that finishes you should be back to the ! recovery screen.
By the way, if you are going to go through all the videos again, would you mind letting me know any issues you run into so we can fix them for the everyone else?
July 10th, 2009 at 2:56 pm
Hey David,
Thanks for the quick reply… I figured out what was wrong. I used the two provided files, flashed the original SPL and when I rebooted I got into Cyanogen’s Recovery image but when I tried again (after the SPL flash) I got the correct rainbow screen which assured me that the SPL had flashed correctly. From there I flashed the original DREAIMG.nbh and now I am stock again. Also, I think your right, I am pretty sure the DREAIMG.nbh flash is what overwrites the recovery image because once I flashed DREAIMG.nbh I was back at the stock triangle and exclamation point assuring me that I am rid of Cyanogen’s image and truly back to stock.
I plan on starting from scratch like I said before so I will go thru the vids AND the text and let you know what I find. I’ll post any necessary edits in their respective tutorial comment section. Thanks for all the hard work again. Its nice to have a place where everything can be organized and not have to search through post after post, thread after thread to find what you need.
BTW: I have confirmed via the bootloader that the radio DOWNGRADES back to stock by applying the DREAIMG.nbh update FYI
From the bootloader I am now at
DREA100 PVT 32B
HBOOT-0.95.0000

I have a question. I did all the steps to a “T” I put the files on card changed to update yadda yadda and well I made a mistake and hit alt-s first…well the phone restarted but I took the battery out then I redid everything making sure to hit alt-w before alt-s after that I loaded the screen for the DREAIMG and went through that but right as it was done I get update terminate update fail. has something gone wrong by chance?
July 10th, 2009 at 8:05 pm
P.S. Every time I try the home+power or even just a normal load it takes me to the DREAIMG screen.
July 10th, 2009 at 8:30 pm
OK sorry for this but please ignore my last post. I figured out what was wrong. When I copied both files over to the sd card it had finished the SPL but did not finish the DREAIMG.nbh file so it was trying to load in incomplete file. I just recopied only the DREAIMG file and boom all good now.
July 11th, 2009 at 3:38 am
Hi david,
I’m currently using a
JF1.51 CRB43 ROM
DREA110 PVT 32B
HSPL10.95.3000
CPLD-4
RADIO-2.22.19.261
I was tinking of changing to Cyanogen v3.6.5 ROM, my question is, do i need to install a new radio, spl, and cyanogen recovery image before installing his ROM?
July 12th, 2009 at 4:28 pm
Hello Chris,
Other people seem to be having an issue with the Dreaimg file with the same error coming up. On XDA a lot of people are saying that they had to redownload the Dreaimg file and put it on their card again to fix it (some even had to do this multiple times before it worked). Your slip up with the Alt S instead of Alt W is no problem (you should do an Alt W first but it is a precaution really).
July 12th, 2009 at 4:30 pm
Hey Chris,
First off, glad it worked!
Second off, wanted to thank you for posting your solution! A lot of other people had this same issue and I had a hunch it had to do with a corrupted/incomplete Dreaimg file. So now we know it does and how to fix it.
July 12th, 2009 at 4:48 pm
Hello Az,
You would really just have to check his thread for that info. He would most likely post *Requires new SPL and Radio somewhere in the first of second post of the thread if it does.
PS The radio you have is the most up to date so do NOT under any circumstances update it, unless you really like looking at the G1 logo for hours
July 15th, 2009 at 9:01 pm
I did the last night and I still haven’t received my cupcake update..how long should it usually take and is there a way I can have my phone search or call for the update?
July 15th, 2009 at 9:29 pm
Love the site very helpful thanks for it…my question is if I were to unroot and get the the rc29 stock build could I go from there to reroot my phone or would I have to wait for the OTA update then follow the root guide?
July 15th, 2009 at 9:31 pm
Hey Dre,
Call T-Mobile and tell them you never got cupcake and you would love to have it
See what they say, they might have a way to get it faster. If they do, would you mind posting it here for everyone else?
July 15th, 2009 at 9:33 pm
Hello Chris,
You can unroot and get to RC29 and then just follow the root procedure from there.
July 15th, 2009 at 9:34 pm
Ah ok thanks David and again great site…
July 15th, 2009 at 10:20 pm
I just called tmobile, I told him I only had the phone a couple weeks and he said I should have received the update within 3 days of activating my phone. He took all my phones info (version,baseband,etc) and said I should receive it within 3 days if not call back. He thought it was weird that I was on v. 1.0 but I just told him that’s how its been since I got it.
July 16th, 2009 at 6:08 am
umm… call me a dumbassss but. I got excited and only installed the original spl and put it into my phone and i bricked my phone. If i use my friends G1 to access my sd card will I be able to install the DREAMIMG file in it so I can downgrade it? iBe.JoshY@gmail.com
July 16th, 2009 at 10:40 am
plz i have problem in root my g1

when i root dreaimg.nbh says
loding and 0020080
not allowe
plz helpe me
July 16th, 2009 at 12:38 pm
Hey David I was reading through the post for unrooting and well I was wondering something. I am helping a friend unroot his G1 cause he would also like to start fresh and new but he has CYO’s recovery image. Now I transferred the files renamed it to update and all that and did a wipe and install but when I want to go to the rainbow screen it still loads into the recovery image is there a way around that?
Side note: I personally did not have any recovery image from anyone just the normal one so I am learning on those.
July 16th, 2009 at 12:42 pm
Hey Chris,
Once you finish the entire UnRooting process (you need to do the whole process and load the DREAIMG.nbh file) the recovery image will be back to stock.
July 16th, 2009 at 12:49 pm
Hello Amr,
Follow the steps in the FAQ at the bottom of the tutorial (I also reuploaded the DREAIMG.nbh file so hopefully that will help some people with this error).
July 16th, 2009 at 12:50 pm
Hello Josh,
Just read the FAQ under the tutorial (I also reuploaded the DREAMIMG.nbh file so hopefully that will help everyone).
July 16th, 2009 at 12:51 pm
Ah ok…Sorry for being a stickler on this lol. Well I tried again I loaded the two files named the one to update wiped, then alt+s to load update. Went fine hit home+back to reboot, when G1 screen popped up took battery out, put battery in held camera+power button and no rainbow still loads G1 screen then goes into recovery mode again…hmmm kinda odd.
So steps 1-7 work fine but cant get to 8. P.S. Sorry for the headache…tylenol is on me
July 16th, 2009 at 12:51 pm
Hello Dre,
Ok, no problem. Should be fine, let us know if it comes in 3 days.
July 16th, 2009 at 4:03 pm
Hmm still very odd the G1 is still loading onto the Cyogenmod recovery screen even after trying a wipe and install.
July 16th, 2009 at 4:05 pm
Actually David I fixed it finally lol sorry for cluttering up with my questions.
July 16th, 2009 at 4:42 pm
Hello Chris,
No problem, what did you do to fix it?
July 16th, 2009 at 7:01 pm
Okay, well, here’s my problem, I’m running jf rc33 and then I followed anthony’s 1.5 update on youtube and I’m tired of all of the crap it gives me a 1.5 firmware with a PLAT-RC33 build and it’s now an HTC Magic. and I just wanna downgrade back to my regular rc29 T-Mobile G1 and get my OTA 1.5 update, but when I install the original (alt+w alt+s home+back) it takes me to the icon where a arrow is pointing down at a box and then turns off, and goes to my G1 screen- I then remove the battery, replace it and then I hold camera and power and it takes me BACK to recovery mode. My gtalk is – iBe.Joshy@gmail.com and I’m always available. I really want my old phone back :\ I regret rooting
July 16th, 2009 at 11:29 pm
im trying to flash the “update” to my phone. when i do the Alt-S thing it says locating, opening, no signature, aborted. what am i doing wrong?

I actually found the 1.5 update for unrooted g1’s. I installed it and it works perfect
July 18th, 2009 at 5:05 pm
Hello Bryan,
That would mean you either should redownload the update and try again or that you do not have root access and so you do not need to do the unroot process.
July 18th, 2009 at 5:08 pm
Hello David Rios,
Read the FAQ at the bottom of the post and as weird as it sounds, just keep trying to load the DREAMIMG.nbh file over and over (redownloading it everytime and putting it on the SD card then putting the SD card into the phone) and eventually it should work. This is what others with the same issue did to fix it.
July 18th, 2009 at 5:10 pm
Hello Amr,
That means that either the SPL you are loading needs to be redownloaded and put back on the card and tried again. OR you do NOT have Root access so you are done.
July 19th, 2009 at 5:07 pm
i don’t have root access coz this problem
when i UPDATE.zip
E : No signature
E: verification failed

David, wat if u unroot your phone but u dont get the ota update from t mo what do you do?
July 22nd, 2009 at 12:55 pm
Hello James,
Then you call T-Mobile and say you reset your phone and you haven’t gotten cupcake yet and if they could help you download it.
July 23rd, 2009 at 5:00 pm
Hello!
I tried to unroot my g1 using the tutorial, followed it and Im having a problem at the rainbow screen. After I hold down the camera button and power it says loading and then quickly goes back to the rainbow screen ans says serial 10. I recently updated my phone with JF cupcake version. This is about the 4th time ive tried unrooting my phone with no success. Please help!
July 27th, 2009 at 8:30 am
Hey David, remember be from your HTC Hero ROM thread?
Anyway, I have a question but 1st let me help with Jess issue. If you want you can add it as a solution B to the 1st issue on the faq above. I had the same issue when I started and deleting/retrying did not help in my case.
To Jess and any one else who is unable to get past the rainbow screen with serial 10, your SD card is most likely in a FAT format and needs to be formatted to FAT32. I had the same issue.
- Load your SD card in the card reader and connect to PC.
- Make sure you back up everything on your card. a format will erase all data on the card.
- Now open “My Computer” and right click on the drive with the SD card (Warning! Make sure its the correct drive).
- Click on Format and select FAT32 on the file system drop down and click then click Start.
- Once completed, Copy your files back to the SD card and make sure the “Original DREAIMG.nbh” is at the topmost folder of your SD card.
- Return to Step 8 of David’s instruction to complete the un-root process and you are all set!
Now David, My question:
I got a replacement phone from T-Mobile and I just successfully un-rooted the old phone that had the Hero rom. If I dont get the 1.5 OTA by tonight, could I update my phone with the cupcake rom DRE posted above (http://www.filefactory.com/dlf/f/ahd7aeh/b/4/h/f9cbf8656d75b2b54e2ab37f216ccc62ade6bb2d/j/0/n/US_CUPCAKE_zip)?
- Is this the same as what I would get OTA or should I just wait.
- Also Once I get cupcake, If I decide to go back to the Hero Rom, do I start with your un-root process where I load back RC29, recovery image, HardSPL followed by radio and then the ROM? (I noticed the radio changed when I completed he un-root).
Thanks again for all the help David.
July 28th, 2009 at 12:53 pm
I hav a question for David or clemshady wat is a card reader and my fromat says fat32 I cant choose any other format. So wat do I do?
July 28th, 2009 at 3:11 pm
Hi i have downloaded these 2 file put on sd card done every thing what you say but when i get to the rainbow screen it say “not allow” please help
July 28th, 2009 at 6:53 pm
Hello Steven,
Do you have Root at the moment? Not allowed is usually a sign that you don’t have root.
July 29th, 2009 at 8:19 am
James, A memory card reader is a device that can read flash memory cards and transfer their contents to a computer. It usually comes with your SD card. You insert your SD card in the card reader and insert the card reader in your computer (as long as you have a PC that has the slot)
My comment regarding FAT32 format only applies to anyone that gets stuck on the Serial 10 rainbow screen while following David’s above instructions. If your SD card is in a FAT format, it may not work until you reformat it to a FAT32 format. (That worked for me)
If you already have a FAT32 card then you should be fine. BTW, what issue are you actually having?
July 29th, 2009 at 7:57 pm
Thanks for the quick answer…I keep gettin stuck on the rainbow screen when I press the camera and power button it comes then says loading then it gose back to the rainbow screen and says serial 10 and nothing happens.and it says not allowed
July 30th, 2009 at 3:47 am
hey thanks cuz i kinda messed my phone up i had hero runing and i tried to put drizzys version of hero on my phone with out know you had steps to do like you did the hero vers i had so it wouldnt let me flash or or go back to my old hero so i had to restart all over i have more Questions can you email me and i will give my numb to talk about my quest for the g1 thanks though man
July 30th, 2009 at 3:50 am
I got the serial 10 rainbow screen but did not get a “not allowed”. Like David said, make sure you already have ROOT on the phone. If you do have root and your card is a FAT32 format, I will recommend to wipe phone, re-format SD card to FAT32 and try process again. Otherwise, please await David’s response on this one. Good luck!
July 31st, 2009 at 1:40 pm
Hello James,
Read the comment(s) and FAQ about this, it happens every now and then.
July 31st, 2009 at 1:47 pm
Thanks Clemshady for helping! Really appreciate it!
July 31st, 2009 at 3:55 pm
i dont have the topmost folder,but i see top and there are files in there…
August 2nd, 2009 at 1:23 am
Hey I can’t get it to work… I did step 1 to 8. And there were no rainbow screen. I did see the gray screen, but it says NO FILES or something. HELP PLEASE… I have Fireware 1.5 the HTC Magic as a Model number! Thank you very much!
August 2nd, 2009 at 1:56 am
help! I was going about unrooting and lost my SD card. I was to the point of trying to get the Dreaimg.NBH to work, which is wasn’t locating for whatever reason.
So now what? Can I just throw dreaimg.nbh right on my new FAT32 sd card and camera+power it on or what?
August 2nd, 2009 at 2:46 am
My pleasure David. You helped me see another side of the G1. I want to help others do the same.
To Lance: “Top” or “Topmost” folder does NOT mean a folder with the name “Top” or “Topmost”. It is the main storage space on your SD card. In other words, anything stored in your SD card but NOT INSIDE ANY FOLDER is considered to be in the “Topmost” folder. Hope this helps. Good Luck.
August 2nd, 2009 at 10:27 am
Hello, I am downgrading from Hero…(want to start fresh) so I went through the steps and when i get to the rainbow screen it says no image file…what did i do??? Thanks for the videos i find they are very easy to follow then the others…

August 3rd, 2009 at 12:44 pm
Hello,
I have the JacHero 2.3.6 ROM loaded on my G1 and I was wondering if these steps also work if I have a Hero ROM loaded. Because I might just unroot my phone for a while. And also, once unrooted, will I continue to get OTA updates (like when my phone was new and not rooted or anything)?
August 4th, 2009 at 4:30 pm
need some help…well i had a rooted g1…and out of nowhere it got me into the rainbow screen and now i cant get passed that screen i haved tried the alt+w and then alt+s and its not working…is there anything i can do
August 4th, 2009 at 6:50 pm
Andres, I also un-rooted my G1 but later went back to Hero. (Once I had the hero experience, anything else didn’t quite do it for me). If you follow the procedure on this page, you will get back the original firmware version 1.0. Within another 24 to 48 hrs, you will get the OTA to update to cupcake (1.5).
August 5th, 2009 at 2:01 pm
Okay thanks clem. I just wanted to make sure, just incase I need to send my phone in haha.
August 8th, 2009 at 11:21 pm
ok when i hold home and the power button it takes me to a screen with a exclamation point in it. so i press alt w and it turns my phone off and back on. then when i press alt s it says…E:can’t open/sdcard/update.zip (no such file or directory) installation aborted. i am really confused. is there any kind of way you can give me a step by step process please? please and thank you
August 10th, 2009 at 1:07 am

Hey guys I have a problem..I just rooted my phone an change the radio an stuff,.. now my google map is about 4 blocks off.. how do i get back the original radio so that i can use my map again .. or is there another solution 2fix this…
August 17th, 2009 at 11:45 am
Hello Richard,
I have a full time job. I do NOT get paid to do this. As any of the Devs would say, try Googling the error and see what others did to replicate and solve it. Noone on here has any responsibility to help you because you are having issues (when plenty of people are doing just fine), we help out of kindness. So stop leaving rude comment(s) because you are frustrated. I understand you are having troubles but being rude won’t get you any help.
Also try formating the SD card first then putting the file on there, also make sure the file is showing up in your computer as a .nbh file and not just a generic file. This happens sometimes when you download it, the computer turns it into a different file.
August 19th, 2009 at 6:01 pm
after hitting the alt +s. how long does it take for installation to complete.. my phone is stuck at this screen
August 23rd, 2009 at 12:03 am
Please Help! im stuck on the G1 screen and i dont know how to go back. i started the process and i dont know where i got lost.
August 23rd, 2009 at 12:41 pm
Hey Guys, thanx again for the great vids…I attempted to un-root my G1(I currently have Cyanogens 1.4 recovery image and twistedumbrellas Casper hero rom) I followed the video instructions, but when I go into recovery, I still get Cn Recovery img instead of the original) and after alt w and alt s my phone continues to go back CN recovery, no rainbow screen or the white screen like in the video to update, any suggestions? Thanx
August 23rd, 2009 at 12:52 pm
Sorry for the repost of the Cyanogens recovery guys….
August 23rd, 2009 at 2:11 pm

August 23rd, 2009 at 5:38 pm
im trying to unroot my g1 from the cyanogenmod v1.4 so i can upload your new img
August 23rd, 2009 at 8:08 pm
Is it not possible to create an upgrade that bypasses the Initial Google Mail setup? I am stuck waiting to root my G1 simply because my T-Mobile PAYG sim wont let me. I assume its because there is not data add-on???
I have WiFi but can’t get to setting to turn on the Wifi to do it. I have now had to order a sim with internet to hopefully get going again.
August 23rd, 2009 at 8:15 pm
Guillermo: Take the battery out and try again. I had the same problem downgrading to RC29. Re-format the SD to Fat32 and Check the filename is correct then hold Camera and Power to flash. If no luck the img is corrupt.
August 24th, 2009 at 7:30 am
where can i download from another site the rc29?
Thanks!!! please help still stock on the rainbow screen!!!

i am having a problem after the update.zip i reboot hold camera and the power button but the rainbow screen nver shows up just the android system recovery help
August 26th, 2009 at 9:52 am
I previously got root via recovery flasher and did apps2sd Using Cyanogen’s recovery tool to partition a 8GB SD card for Apps2SD
Do I have to unroot and do it over or can I just flash Amons Ra’s recovery Image and them format my SD Card I want to get Fat32+Ext2+LinuxSwap
August 26th, 2009 at 12:33 pm
Hello David M,
If you are a bit more experienced then no you don’t have to (although it is always recommended and isn’t very hard).
You can instead just download the recovery image from our 1 click rooting post, then load it via Fastboot, do you know how to do that?
August 26th, 2009 at 12:53 pm
yes that was my question thank you!
I’m going to up grade to your recovery image, thank you again keep up that great work!
August 27th, 2009 at 4:21 pm
Help, I’ve been trying to go back to factory settings and unroot my phone, Its simply will not work. I can’t get to the rainbow screen, what am i doing wrong? I have jf 1.42 and dev. i can’t get this off my phone, help. my phone doesn’t receive yahoo email and this is because its rooted please help unroot
August 27th, 2009 at 4:31 pm
Hello Drew,
First off the rooted shouldn’t effect your mail at all. But no problem.
You need to hold down the Power and Camera button to get to the rainbow screen (this may also be a white screen with skateboarding androids on it by the way).
August 27th, 2009 at 4:51 pm
i tried it it won’t work. Dude after i loaded the update to the card and the dream. i cut the phone off, hold home and power, then wipe the phone and then hit alt and s, then back and home. i took the battery out. i put it back in and held the camera button and power it went to the g1 screen.
August 28th, 2009 at 12:43 pm
Hello Drew,
Go back to recovery mode and load the SPL again. This time reboot and just wait. It will reboot and you will see an icon that shows something coming out of a box (weird I know). Let that finish and then it will reboot again. It may reboot to the recovery screen and if it does then take out the battery and do the camera and power step and continue. If it reboots a few times and goes to the G1 logo, just wait for about 20 seconds. If it still doesn’t move from the G1 logo, THEN take out the battery and put it back in and do the camera and power step and continue.
The issue is that when you load the Original SPL it has to reboot for a bit and load other things as it is booting up. So we have to wait for that to finish then it should get stuck, that is when we take out the battery and continue.
I’m adding this to the reported issues for the MyTouch unrooting and the G1 unrooting. Please let me know if this solves the issue.
August 28th, 2009 at 1:47 pm
do NEED to have a class 6 micro sd or does a class 4 do the trick…reason i ask is cus recently my jachero rom lags, i’ve got apps2sd but i need to start from scratch so do i need class 6 or will this do?
August 28th, 2009 at 1:55 pm
Hello David,
Class 6 is always best, but I you can try it with the class 4 for now and see how you like it.
August 29th, 2009 at 2:42 am
so i downloaded the files renamed the spl and unzipped the other file, put em on my phone, turned on w/home and end pressed alt w and the progress bar starts up then reboots! my phone is wiped but it doesn’tgive the update optio, ro give me a chance at it… why? i need to unroot and reroot so i can load the hero rom… thanks!
August 30th, 2009 at 11:45 am
Once UN-rooted will I get the CRC1 update? I download the cupcake update from the link above. Also Im having trouble with getting my phone to connect via USB. Thanks
August 30th, 2009 at 11:45 am
My Phone wont Mount.
September 1st, 2009 at 10:31 pm
i feel like i have a different g1 then yours every time i tried to download the dreaming file it doesnt work still stuck at the rainbow screendoesnt go to the grey screen that says press power to intall. i need as much advice and tips on reseting my phone so i can reset it becuase i i tried to root alot and tried to use the new method but i had one problem it didnt let me do a custom flash so i had to choose cynagen 1.4 i think then i didnt have all the options like the guy did and i couldnt partoin my memory stick and the rest.
September 2nd, 2009 at 2:02 am
Hello Domo,
You may need to redownload the file and make sure that it is on the root of the SD.
September 3rd, 2009 at 6:19 am
Hi, great info!
I’ve got the developer version of the G1-phone. Would this procedure allow me to restore my phone as well? (Don’t really want to unroot it as the dev phone is supposed to have root access, but remove the hacked JF.151 rom) Or would I need a different image-file/spl?
Thanks!
September 3rd, 2009 at 11:06 am
Hello Hoah!,
That’s a good question. I would assume (as I’ve never tried the procedure on a dev phone) that it would make you lose root, you would have to use the custom search bar under the post to find the ADP1 version instead of the RC29 version.
September 3rd, 2009 at 4:36 pm
ok… i need help… my phone qwas fine.. an then all of the sudden it says no service.. no network are anything.. i tried to reconnect it to a network.. but it didi not work.. i am running a rooted g1… so i don’t know what to do to get my service back… but wifi still works need help…
September 3rd, 2009 at 5:54 pm
Hello Kareem,
Unroot and reroot the phone, should work from there. If not, then it’s not the phone it’s T-Mobile.
September 3rd, 2009 at 7:58 pm
Thanks Unlockr.
I found official files on the HTC homepage, so will try those.

When I click the Original SPL link it takes me to a site that requires a user name and password…. what should I input?
September 5th, 2009 at 2:30 am
ok i did that but still no signal bars.. i mean my phone is off did not pay bill but did not think that it would effect my signal.. so i guess it is t-mobile.. i mean i was using my phone fine without paying the bill.. for like a month.. so i guess they can stop my signal.. i will have to wait to be in the area of some wifi to let to let you know what happens… did you know that you can still e-mail an g talk with out paying bill? but i will let you know an thank you… i also am on flex plan.. if i go get minutes do you think my signal bars will com back????
September 5th, 2009 at 1:59 pm
Hello GEM,
Just sign up for a free account.
September 5th, 2009 at 2:01 pm
Hello Kareem,
That is T-Mobile definitely. You don’t pay your bill, they shut off the phone (might take them a month to shut it off but they will eventually).
That’s interesting that you were able to use so many things without paying the bill…
And yes if you pay your bill your phone will turn back on lol
September 6th, 2009 at 11:42 am
i have tried looking around im confused. ive tried doing this and im stuck on the rainbow anad then it flashes to a gray screen that says no image file! what do i do? someone please help me s0ldradi0@gmail.com
September 6th, 2009 at 12:54 pm
nevermind, i got it. i just kept re installing dreaimg file
September 6th, 2009 at 11:27 pm
One thing i had to figure out the hard way is the dreaimg zip never fully unzips the MAC file. I guess this is cause i have a pc. but 1 time i tried installing the whole zip file cause i didnt know to unzip it. Maybe you should mention this at the very top of the page so idiots such as myself dont have to figure it out the hard way. Im currently waiting for the cakecake update. Last time i got impatient and just installed The dudes Cupcake and obviously couldnt proceed with the “rooting” video…hence not being able to get the amon ra recovery image successfully installed there fore not being able to ext2/3 my sd therefore not being able to GET HERO RUNNING SMOOTHLY!!! WHEW! hahhaa So im am going to patienly wait…This is a latter type of thing but i do appreciate the tutorials dont get me wrong!!!
September 7th, 2009 at 11:51 am
How do you put movies on the g1, what software do you need to rip the movies to the right format? where can i get it for free?
September 10th, 2009 at 1:04 am
i try all this step but my phone don’t want to load the file some one help me please
September 10th, 2009 at 9:59 am
I followed info from xda’s website to root(which failed) so i downgraded cupcake. Now i want to go back to cupcake using your method. I get from recovery utility E: Can’t open /cache/recovery/command and the update will not install. What could i be doing wrong please help.
September 10th, 2009 at 10:41 am
Hello Can’t get cupcake back,
That means you are not rooted (like you said you weren’t). So just skip the update.zip section and do the loading of the Dreaimg section (put it on the memory card, boot into bootloader and load that) and you should be back to RC29. Then just follow the steps at the end to get back to cupcake.
Then if you want to try again to get root, just follow our 1 click to root procedure for the G1. MUCH easier. Then load a custom ROM (cyanogen is recommended from our Downloads section) and that’s it.
September 11th, 2009 at 10:34 am
how will i know if my phone is unrooted. i waited all night for it to updated back to 1.5 and it never did. i think i might be stuck at rc29 forever! can you please help
September 11th, 2009 at 10:44 am
if my phone is unrooted should i still be able to “enter reboot enter” to reboot the phone… because im still able to do so. ?????? pleeeeaaaaase help. i just want my cupcake back. root was an epic failure for me. id rather try the “1click” way that you posted up.
September 11th, 2009 at 11:06 am
Hello VRtheTrooper,
Just do the last step in the procedure to get back to cupcake. Then download terminal emulator from the market and type su into it and it should say permission denied if you are unrooted.
September 12th, 2009 at 7:47 pm
I was trying to put a rom on my g1 for the first time, I followed all the steps (1 click root. installing a rom) but I failed to read that i needed a SD Card Adapter. SO I got all way up to that step, I wiped my rom and can’t get it back. My G1 will not go pass the G1 screen. I tried the unrooting steps, I took my sd card and put it in my wifes G1 and put all the files on my card that I needed to unroot the phone. I can get all way up to the colorfull screen (holdind camera and Power) but it won’t load… Please Help Me someone
September 13th, 2009 at 12:50 pm

I downloaded the “update”, wiped, rebooted… took off the battery and pressed OFF+Camera and I see NO rainbow but do see 3 android things at the bottom with HBOOT FastBoot Mode. If I select FastBoot it gives me 4 options HBoot Mode, Reset Device Restart to HBOOT, and Power Down….. I cant even turn my phone on anymore… it just loops the HERO screen…. PLEASE ADVISE ASAP… thank you

September 14th, 2009 at 9:25 am
Hello Brandon P,
Read the reported issues. Redownload the .nbh file, put it on the SD card and redo.
September 14th, 2009 at 10:20 am
Please help…. this is day two without anyphone at all:

September 14th, 2009 at 12:16 pm
Hello Gem,
Instead of unrooting, just download the Cyanogen ROM from our downloads section, put it on the SD card, rename to update.zip (like you did with Hero) then boot into recover (home and power) and wipe and apply the update.
September 14th, 2009 at 2:17 pm
ok im sending my phone back to get repaired, so how do i get my memory back to my card again?
September 14th, 2009 at 4:29 pm
Hello Mookieboy,
I dont understand the question, you dont send your memory card in when repairing. Just unroot, then just send the phone, no battery, no back cover, no SIM, no Memory card.
September 14th, 2009 at 6:45 pm
So I rushed home… deleted everything from my SD and put Cyanogen ROM replacing it with update… wiped and then applied… it says
E: No Signature (16 Files)
E: Verification Failed
Instillation Aborted
Am I gonna have to buy awhole new phone *frown* this is day two with NO PHONE… please help.
I can not format this SD cuz I am unable to even get onto my phone… it just loops on the HERO screen
September 14th, 2009 at 10:42 pm
ok so, i installed cupcake, and when i power my phone up it makes me log in with a google account. I have a at&t sim card and its not letting me log in, help? what do i do? i think the unroot locked my phone back to t-mobile
September 14th, 2009 at 11:20 pm
Hello Brandon P,
No it most likely did not relock the phone, the issue is that it erased the ATT APN from the phone. Do you see signal bars when your ATT SIM card in in the phone?
If so then this is what happened. Just click Menu and click APN settings and put in the ATT ones….
September 14th, 2009 at 11:25 pm
Hello GEM,
You will not have to buy a new phone, calm down lol
Try a different ROM from our downloads section (or use the search bar there to search various other sites for a ROM).
Keep trying till one works. It may also help to format the card (you can do this on your computer by putting the SD card into a card reader and putting into the computer by itself, then right clicking it and clicking format. If you do this though a Hero ROM won’t load until you can partition the card in the recovery screen.
Good luck man, and don’t worry I have yet to see a phone that is completely bricked
September 15th, 2009 at 12:38 am
Is there a way to skip around loogging into my google account? so i can turn on the wifi instead of using data services?
September 15th, 2009 at 12:43 am
ROMS? I am such a beginner… I just want my phone to be back to cupcake or what ever…. I do not want the HERO…. I tried did what this says BUT when I hit camera+power it goes to a screen with three androids at the bottom… HBOOT FastBoot Mode. If I select FastBoot it gives me 4 options HBoot Mode, Reset Device Restart to HBOOT, and Power Down….. I cant even turn my phone on anymore… it just loops the HERO screen… I also have now tried the Recovery thing you suggested and it gives me the error listed above… BLAH I SUCK
September 15th, 2009 at 9:58 am
Hello Brandon P,
No not unless you load a custom ROM.
September 15th, 2009 at 10:36 am
…. after many trials… all errors and 3 days withouth a phone it looks like I will have to give up…. I formatted my SD… re downloaded the links… put them on the card, removed them countless times…. all works until I get to the rainbow screen…. it says “serial 10″ … cant get past it… any last thoughts ([lease give steps if possible… I am new to this phone stuff)?

Hello GEM,
Yup, at the bottom of the procedure there is a search box that says to use if you are having issues. Type serial 10 error into it and see what comes up, it ONLY searches sites that may have a solution. Good luck!

Are you using a T-Mobile SIM card?
September 15th, 2009 at 6:05 pm

September 16th, 2009 at 4:04 pm

September 16th, 2009 at 4:18 pm
im trying to unroot my phone everytime i press camera and end button it says serial 0 does it matter that i have on cyanogen recovery image?
September 17th, 2009 at 8:23 am
Ok, i followed steps one by one but when i try to go to the recovery mode the phone gives me an error screen….. a picture of the phone with an exclamation symbol inside of a triangle. i have a 1.5 CRC1 version.
please i have tow days trying to get the HTC hero rom and i can’t do it unless i unroot and then root my phone.
Thanks
September 17th, 2009 at 8:51 am
Hello Fredrick B.,
That isnt an error, it is the phones default recovery screen (you can hit Alt L to bring up the menu). That recovery wont work and it means you didnt load the recovery image correctly. Try again and read the reported issues at the bottom of the post and make sure you follow them.
Good luck!
September 17th, 2009 at 2:05 pm
ok i finally got the rc29 but it’s been 5 hours and still no cupcake update……
September 17th, 2009 at 3:33 pm
I waited until the recovery screen came up again after running the update, then continued to remove battery and load the rainbow screen but it still did not work!
I think I need the original Radio if that is possible…
September 17th, 2009 at 4:06 pm
Ok think I’ve found the problem but not a clue how to fix…
When I load the rainbow screen it says checking and then flashes no image file. Any way to fix this please?
September 17th, 2009 at 7:49 pm
Hello Fredrick B.
There is a way to manually update at the bottom of the post. Step 11….
September 17th, 2009 at 7:54 pm
Hello Ollie C,
Read the reported issues.
September 18th, 2009 at 4:42 am
I made a video to show the problems I am having. This video has a 20 seconds wait which the instruction told me to do. I also tried 5, 10, and 15 seconds wait and it still does not work.
If you can see what i am doing wrong, please let me know. This video starts with me transferring the files to the G1.
Thanks!

September 18th, 2009 at 10:07 am
Thanks, but it says that the site is down for maintenance, is there another way to get the cupcake manually?
September 18th, 2009 at 10:31 am
Ok I got past the Serial0 problem by formatting my SD card to FAT32..
Now when I load the rainbow screen it goes:
Loading…
Checking…
Then flashes to:
00028002
not allow
Any solutions? Been trying to unroot for days now. Ive wiped and flashed a dozen times and still nothing.
Thanks
September 18th, 2009 at 1:33 pm
does anybody knows where to get the cupcake?
September 18th, 2009 at 2:39 pm
Frederick B.

September 19th, 2009 at 9:10 am
Hey when ever i power and home i never get the boot menu just the triangle “!” what am i doing wrong? Help Plz
September 19th, 2009 at 12:14 pm
Hello Lanceezy,
Short answer, no.
You have to root to load ROMs.
September 19th, 2009 at 12:15 pm
Hello MrJ1s,
That means you never had a custom recovery image. So just hit Alt L at that screen and the menu will pop up.
September 19th, 2009 at 5:05 pm
is rooting your g1 harmful?
September 19th, 2009 at 6:05 pm
Hello Charlie,
Nope.
September 20th, 2009 at 1:46 pm
So if I have no APN’s it wont use my data? right
September 21st, 2009 at 5:05 am
Hi,
Great site firstly, nice to find everything you need in one place
I’m having the problem where the first splash screen comes up, then the phone reboots, and repeats this. When i hold down the Camera Button + End nothing happens, as well as when i hold down Home + End nothing happens. It just keeps repeating the splash screen reboot loop. The only way i can stop it is to remove the battery.
Any advice on how to fix this would be appreciated.
September 23rd, 2009 at 3:39 pm
ive got the cyanogenmod + jf 1.4 and the spl download does not complete and the g1 also doenst go to the page that u get when u hold the camera and power button
September 24th, 2009 at 5:22 pm
hello, I’ve ben browsing the comments and haven’t come across anything that mentions being able unroot if your are running a g1 without a data plan. Is it impossible or is it in the realm of possibility to bypass the requirement of a data plan or us the wifi? Thanks if you can help that would be fantastic.
September 26th, 2009 at 3:49 am
omg you are the best. i was so pissed when i rooted my phone and then it messed up so i jus gave up and wanted it to go back to the cupcake version. thank you so much.

September 28th, 2009 at 12:11 am
I need big Help guys im stuck on the G1 logo and wanted my phone to be back to the original SPL and default. I only could go back to the recovery screen. I’m scared now i didn’t load no roms but i loaded the latest SPL and radio. I dont have the format section on my recovery screen. Can Anybody help me Please?
September 28th, 2009 at 1:14 am
Hello brick4byrd,
Just goto the How To load a custom rom procedure and do the last section; use an sd adapter to load a custom rom onto the sd card, then put it into the phone and boot to recovery, wipe and apply the update.
Then you should be able to get to the home screen.
September 28th, 2009 at 1:58 pm
i keep getting an error when i try to wipe and flash update.zip it keeps saying:
E:No Signature (5 files)
E:Verification failed
Installation aborted.
September 28th, 2009 at 2:10 pm
Hello Kyle2blue,
Download the file again and try again, otherwise that means you dont have root.
September 28th, 2009 at 2:22 pm
my firmware is 1.1 and my build number says:
kila-user 1.1 PLAT-RC33 126986
ota-rel-keys, release-keys
is this the stock setting? because my speaker broke in under a year and I have to send this one back for a replacement next week and need to unroot.
September 28th, 2009 at 2:23 pm
Link for cupcake doesnt work and cant find a working one
September 30th, 2009 at 8:41 pm

THANK YOU!
September 30th, 2009 at 11:24 pm
HI, i really want to get the hero thing but the problem is that i dont know anything about unlocking or unrooting… so, should i just follow the tutorial and get done with it?? …. also i wanted to know if i did unroot my g1 will it get updated or should i update it manually??
thank u
October 1st, 2009 at 12:58 am
Hello Al,
Just do the 1 click root procedure then the How To load a Custom ROM procedure.
To undo and get back to the way you were before you began, goto the How To Unroot procedure and yes you will get OTA updates after that.
Good luck!
October 1st, 2009 at 1:07 am
Hello Utkarsh,
You are very welcome! Thanks for coming to our site!

October 2nd, 2009 at 11:56 pm
i cant down load the original spl file it directs me to a different page ….. what do i do
October 4th, 2009 at 9:02 pm
whenever i try applying the update of original spl, there’s always a failure even if i wipe and have it named update or update.zip
October 5th, 2009 at 2:46 am
It says I’m on RC29 but I didn’t run the cupcake update? Do I still need to?
October 5th, 2009 at 11:10 am
Hello Mason,
Yes, you need to run the cupcake update.
October 5th, 2009 at 1:19 pm
when i turn off the phone and turn it on holding the home and undo button, it says” This operation will delete all your personal data, and reset all settings to manufacturer default, or press other keys to cancel” is it right? cause then i tried to press alt-w but nothing happened (i’m trying to downgrade from my doughnut)
October 5th, 2009 at 1:27 pm
Hello Paul,
No clue what buttons your pressing or why lol. You hold down Home and Power (what’s the undo button, back?) to get to the recovery screen (if you never loaded a new recovery screen then it will have a ! symbol. Just hit Alt L to bring up the menu, then Alt W to Wipe and then Alt S to apply the SPL (which you renamed to update.zip and put in the correct place on your SD). Then once it is done, turn off the phone then boot into bootloader (camera and power) and it should ask you if you want to continue to load the DreaIMG file. You say yes and then upgrade to cupcake as per the instructions and then you can goto the How To Root and How to Load a Custom ROM procedures.
October 5th, 2009 at 1:52 pm
while on donut (G1) taking all proper steps which i’ve unrooted before, after wiping the phone and applying update.zip it says verifying update (5 files) installation failed signiture missing update aborted. What am i doing wrong, i cant seem to be able to unroot G1 with donut so that i can get cupcake to be able to root….
BTW ive kept doing the process over and over as instructed and no dice.
October 5th, 2009 at 1:57 pm
Hello 5*G,
Do me a favor, try to skip the loading of the SPL. Just put the dreaimg.nbh file on your sd card and then turn off the phone and turn it back on by holding down camera and power (to get to boot loader) and it should ask for you to push a button to continue to load the file. Do that and once you are done, then goto the last step and load cupcake. Please post here if that works!
October 5th, 2009 at 2:01 pm
Thanks but i have one more question, i tried to apply the SPL on but everytime i try to apply it, it says
E: Verification failed
Installation aborted
(i put the original g1 spl and the dreaimg.nbh in sd card like where you first open it so idk whats wrong with it
October 6th, 2009 at 2:19 pm
please help me. i have a rooted phone CyanogenMod-4.04 . and i can get it unrooted i tried the 1st step and when i click ALT S to load the update.zip it says (bad) i really need help cause i want the new update 1.6 donut firmware. or do u know how to get that firmware while phone is rooted?? please help, thanks
October 6th, 2009 at 3:11 pm
Hello Brad,
There is no need to unroot….
Just get the Donut ROM (its the one with the sprinkles in our download section) rename it to update.zip put it on the sd card, wipe and then apply update.
October 6th, 2009 at 3:51 pm
The update yesterday was indeed donut, right? If so, I need to unroot, then update with the cupcake link in order to run a rom like MoDaco??
October 6th, 2009 at 5:02 pm
Hello Zay,
The Modaco ROMs are for the ACTUAL Hero phone fyi, so don’t try to load them. If you want a Hero ROM on your G1 then I recommend the Maxisma ROM in our downloads section.
Yes, unroot using this procedure, then do the 1 click root procedure and the how to load a rom procedure.
October 6th, 2009 at 8:55 pm
thanx
October 6th, 2009 at 10:01 pm
woahh
im in the middle of the cupcake updating and it says

Thanks unlockr
October 6th, 2009 at 10:03 pm
I never rooted my g1 i just started from where it says get back to cupcake.
October 7th, 2009 at 12:03 am
Hello Shatter,
You need to start at Section II. Load the dreaimg.nbh fild (skip loading the SPL) THEN goto the last step (dont skip steps lol)
October 7th, 2009 at 12:09 am

October 7th, 2009 at 12:41 am
Hello Bryan,
Did you do the SPL update or have you not rooted yet?
What company do you have TMobile or Rogers?
October 7th, 2009 at 1:27 am

October 7th, 2009 at 11:39 pm
Thanks a lot for the guide. Worked like a charm.
October 8th, 2009 at 12:16 am
Hello Void,
Glad it worked! Your welcome!
October 8th, 2009 at 5:24 am

October 8th, 2009 at 11:57 am
Hello cclowlow,
If you have donut, you skip loading the spl, just load the dreaimg.nbh in the next section (it says this in the instructions).
October 8th, 2009 at 1:30 pm
i am new to this just do not want to mess it up thanks
October 8th, 2009 at 5:31 pm
I get the “not allow” msg, should I install the rc-7? (since I have a european phone.
October 8th, 2009 at 10:51 pm
Hello Geoff,
You can try that, sure. Do you have a link to the RC7 download and I’ll post it here for other Euro users?
October 9th, 2009 at 2:21 am
hey ive tried unsuccessfully for two days now, and im giving up. Can u plz tell me what to do to get back to normal. Im still rooted but the hero rom i tried to boot was stuck in a bootloop. I tinkered around with the Amon Ra options and it kept saying it could not read my sdcard. I exchanged it for a brand new one… I would like to know how to return to normal, before I mess something up even worse… does my sim card need to be in for this process, cuz ive had it in an old phone since my G1 caught the bootloops…
October 9th, 2009 at 9:19 am
hi unlockr.
i have been using hero rom for a while now, but want to return it to stock… do i updaete the spl and dreaimg. and leave it and wait for the ota update, like in the video. or do i have to flash the cupcake rom myself??
also am i supposed to reformat the card before i start???
help please ASAP!!!
October 9th, 2009 at 9:40 am
another question… will my phone lock to tmobile again??
thanks
October 9th, 2009 at 9:40 am
Hello Zay,
No your SIM card does not need to be in. Just do this process and your all set. You will need your SIM card to get past the Google sign in screen once youve unrooted though.
October 9th, 2009 at 9:45 am
Helllo USman,
Just do this procedure exactly as it is written and you are all set. Did you load a new SPL when you went to Hero? If so then do the SPL part, if not skip it.
Your other option (and the better one in my opinion) would be just to load a non hero custom ROM, you’ll be back to donut and have added features (root access and 5 homescreens, multi touch, etc.)
Only reason you should unroot completely is if you need to send the phone in for warranty.
Good luck!
October 9th, 2009 at 10:19 am
thanx… before i attempt, do i need to format the new sdcard, and the only way i can put anything on my sdcard is to enter recovery mode and mount using the Amon root thing. If i click the turn on usb storage put the original spl and the dreaimg.nbh on there then turn off usb storage could i just go straight to update and then reboot? then hold the camera and end buttons to finish… I kno i’ve been bugging you guys, but idk how else to get the original spl on since i cant boot normally…. Thanx
October 9th, 2009 at 10:19 am
Thanks for the quick reply(need to get this done for tonight- for the weekend).
I just got into this hacking stuff last week after building up the courage to load hero on my phone. Sadly I was dissapointed as all the roms I tried were too laggy.
Now I just want the fastest rom, hopefully donut. Do you have any ideas of what rom I should use? I want to store apps2sd and set cache to sd.
I am currently using the link you provided to Amon RA’s recovery image.
What I am planning to do is, re-partition the sd card, convert ext2.ext3 (if that makes sense), load the donut rom off xda (the 1st link off this page with the expansion):
http://forum.xda-developers.com/showthread.php?t=538456
Then I’ll set cache to sd through the recovery mode.
However I am not sure if all this is necessary and or even useful.
ps. Am I supposed to flash the expansion like the actual rom and do i need to do the cache to sd through the recovery image or will the expansion pack do.
Thanks for your time, and im sorry if I don’t make complete sense, still don’t understand everything thats going on.
Thanks again.
October 9th, 2009 at 10:25 am
Oh, I’ve just notice this rom:
http://forum.xda-developers.com/showthread.php?t=566676
Can you please take a look and advise me please…. This one seems to have the apps2sd and cache to sd included.
Sorry if I seem a little trigger happy, but I’m in a rush to get this done.
Thanks again.
October 9th, 2009 at 12:06 pm
i think i did something right for once… just waiting on the donut ota… thanx for your help. The video was very helpful…
October 9th, 2009 at 1:19 pm
Hello Zay,
That is right, and no you don’t need to format the card.
October 9th, 2009 at 1:21 pm
Hello Usman,
Everything you said is perfectly fine. I would however not load the first Donut (the one with the expansion is over complicated). Just load the one with the Sprinkles in our download section instead and you’ll be all set with Donut, Root, Wifi Tether, 5 Homescreens (instead of 3) and quick.
October 10th, 2009 at 8:55 am
Hey,
This is a first time I root my phone, I was able to successful do steps I and II. I thought I did III correctly, but never ended up with the cupcake on my phone. At the end of the video it says to wait a couple of hours to get the cupcake update. I figured it would be best to just do step III. Was I suppose to do step III or just wait for the update on my phone. If I was suppose to do step III?
If so is there something I did wrong on this step that is a common mistake?
I got to the Loading Roms video, however when it came time to wipe and apply I had 2 update.zip (well one was update.zip.zip). So I figured I messed up somewhere in the step III.
Help?
Thanks in advance, I have read alot of the comments, and I see that you guys respond quickly. Great support!
October 10th, 2009 at 10:18 am
For the ppl who keep getting not allow, a “goldcard” may be the awnser(just google it if you want to know how)
October 10th, 2009 at 11:02 am
Oh and does having a Micro SD HC make a difference?
Ive read that it does and doesnt.
I am currently using an 8 gb, if not then I will return it and get a Micro SD instead.
October 10th, 2009 at 11:18 am
Third post.
as I keep adding update.zip files, do I have to delete the others that are on the sd card? I think I would end up with a couple of update.zip files by the time I get to adding a ROM.
Same thing goes for “META-INF”
October 10th, 2009 at 5:00 pm
Hello Christian,
You can do step III and get back to Cupcake. You need to delete any other update.zips on the sd card before renaming another to update.zip. Then make sure it is update.zip NOT update.zip.zip then you can flash it and be all set.
October 11th, 2009 at 4:28 pm
How long does it take for the Ota to give me donut again? I unrooted to 1.5 and I am wondering if I will even get the update.
October 11th, 2009 at 5:10 pm
I only have this 1 question I unrooeted already …will t mobile send me the donut update or do I have 2 donwload it n do I have 2 delete the file I made wen I unrooted called update or do I keep it? well 2 questions lol
October 11th, 2009 at 5:14 pm
need help, i try to get back to stock rc29 and now the phone wont even turn on.
October 11th, 2009 at 5:40 pm
Hello James,
If you are trying to unroot back to donut, you will have to wait upto 48 hours for the update. If you dont get it by then then call T-Mobile and tell them you are still waiting for donut and never got it. See if they can manually send it.
October 11th, 2009 at 5:41 pm
Hello El3Mend0,
Put the dreaimg.nbh file on the sd card (NOT in any folder) and turn on the phone holding down Power and Camera button. Then it will ask you to update.
October 11th, 2009 at 7:28 pm
i falled the unroot procedure to the letter and still get error message , E:No signature (5 files ) E:Verifacation failed . Installation aborted

Yes hello I just got the 1.6 update yesterday I was wondering if I have to go back to cupcake or can I just root with 1.6 as my version (unrooted)
October 11th, 2009 at 9:15 pm
Let me revise I want to get hero on my g1 so I went to the root tut and it said my phone has to be running cupcake can I still root my phone even with 1.6?
October 11th, 2009 at 10:06 pm
Hello Hungfut,
Skip loading the SPL, goto Section II.
October 11th, 2009 at 10:10 pm
Hello Jacob,
Goto our Fourms and look for the G1 then Modyfing/ROMs and you’ll see a sticky about How To Root Stock Donut.
October 12th, 2009 at 1:14 am
So this means I won’t have 1.6 widegets e 1.6 for throm…and u think there would be a ota for the g1 for the sense ui aka rosie?
October 12th, 2009 at 11:05 am
Hello Jacob,
There are no 1.6 special widgets that I know of. In fact, most of the updates for 1.6 were on the developing side, (support for CDMA, support for different screen sizes, etc.
You would either have to choose a 1.6 based ROM to have 1.6 or choose a Hero ROM to have Hero (for now, until they make a Hero ROM with 1.6 underneath).
No there will never be a Sense UI update for the G1 or the MyTouch
October 12th, 2009 at 2:12 pm
To Help whoever needs it when your unrooting your g1 ….. after u dowload the dreaming nbh file. You have to right click on it and then click extract all dats only way the file will donwload on your phone .that’s how it work for me and thanks unlockr for answering my question

hey james,
thanks for your help….
October 15th, 2009 at 10:38 am
The SPL is not working on the DRC83 build I have. After pressing ALT+W at the recovery screen the screen goes blank and the G screen pops up. I’ve tried pressing ALT+S right after but it doesn’t reboot the .zip, only wipes the phone. Am I missing something?
October 15th, 2009 at 12:40 pm
Hello Charice,
Yes, Skip the SPL section and just load the Dreaimg.nbh file.
October 15th, 2009 at 5:45 pm
No problem rey
October 15th, 2009 at 8:09 pm
everytime i try to upload update.zip it says
no signature (5 files)
verifications failed
installation aborted
October 15th, 2009 at 9:17 pm
Hello Dk2Nice,
Skip the SPL section. Go straight to the loading dreaimg.nbh section.
October 16th, 2009 at 12:36 am
I have been trying to update my g1 from crc37 to donut. I rooted it awhile back with the uk update. I have been trying to unroot it I have tried doing with the spl and dreaimg. It is at the rainbow screen (Serial 10) It will say loading then say no image file. Need help please. thanks.
October 16th, 2009 at 12:43 am
I tried extracting the file. No success. Still says no image file.
October 16th, 2009 at 10:50 am
Hello Dannielle,
Do you have root access right now? Then no need to unroot. Just download a Donut ROM (the one with the sprinkles in our Downloads section is good).
October 17th, 2009 at 6:15 pm
Hey Unlockr and Clemshady,
rememver me well i got this whole root thing down feel like a pro thanks guys

Need help please. thanks.>>>>>>> hi my name is alfonso , and yes i was having the same problem . what no body mention is that you need to “extract: the dreaming.nhd file. after you download it. if you just copy and paste it in to you microsdcard is not going to work.
1. Download the Original SPL:
Original SPL
2. Rename the Original SPL to Update.zip and place it (now named update.zip) on the SD card (not in any folder).
3. Turn off the phone
4. Turn on the phone holding Home and End key till the recovery screen pops up.
5. Hit Alt W to wipe the phone, then hit Alt S to load the update.zip
6. After the update is complete, press Home and Back to reboot.
7. Once the phone reboots to the G1 Logo, turn it off by taking out the battery. Then put the battery back in. *READ THE REPORTED ISSUES FOR A COMMON ISSUE WITH THIS STEP!
II. Load the DreaIMG.nbh File
1. Download the Original DreaIMG.nbh file:
Original DREAIMG.nbh >>what no one mention is here>(( afer download, doble click and extract the file))” if you put the .zip file is not going to work.” nex to 2>
2. Put the DreamIMG.nbh file on the SD card, NOT in any folder. (If you did Section I the phone is off still, take out the memory card, put it in the MicroSD adapter and plug it into your computer to transfer the file over, since your G1 won’t turn on right now if you did Section I above. Otherwise if you did not need to do Section I above, then you can just put it on the SD card normally using the usb cable and the phone).
3. Turn the phone off if it is on.
4. Turn on the phone by holding the Camera button and the End key until the bootloader screen turns on.
5. Hit the End key to start the update. DO NOT INTERUPT THIS PROCESS.
6. Once it is done, hit the trackball to restart the phone. You now are on the stock firmware RC29. You must do the next section to get back to cupcake.
III. Get Back to Cupcake
1. Download the cupcake update from here, then put it on your SD card, rename it to update.zip Turn off your phone and turn it back on by holding down Home and Power to get to recovery mode. In recovery mode (the ! screen) hit Alt L to see text, then hit Alt S to Apply the update.
when it reboots is going to doig twis by it self no panic.
October 18th, 2009 at 12:40 am

October 18th, 2009 at 3:02 pm
I have been trying to get the one click root and the hero rom in my G1, i had donut and followed the steps, went back to rc29, updated to cupcake and was able to see the black screen with a bunch of options, from there i dont know if i should tke out the battery or (home+back button) now when i try to flash it it says something about “phone type /32b” help!!
October 18th, 2009 at 3:03 pm
and if i try recovery boot mode it gives me the (!) screen,
October 18th, 2009 at 3:41 pm
Hello Cisco,
Read the reported issues in the How To Root in One Click post. Then also make sure the ROM you are trying to load is for the G1 Not a ROM for the ACTUAL HERO PHONE.
October 18th, 2009 at 3:43 pm
Hello Kevin,
Follow this procedure but make sure you unzip the file and then put the dreaimg.nbh file that is inside on the sd card not the whole .zip folder.
October 18th, 2009 at 4:45 pm
Hello Operative5639,
Ha you’re welcome! Glad to help. Check out the new Forums lots to learn in there and adding to it and the site as much as I can.
October 18th, 2009 at 4:48 pm
Hello Alfonso,
The file wasn’t a .zip when I uploaded it, thats why it didnt say to unzip, but apparently when some people are downloading it they are getting a .zip. Dont understand why, but I edited the procedure to say to unzip, thanks for bringing it to my attention!
October 18th, 2009 at 4:55 pm
Hello Luis,
Make sure to unzip the file first and then make sure the dreaimg.nbh is on the root of your sd card not in any folders and is spelt correctly.
October 19th, 2009 at 12:12 am

October 20th, 2009 at 4:55 pm

October 20th, 2009 at 5:04 pm
Hello Marcus,
Skip the SPL section and just put the Dreaimg.nbh file on your SD and do that procedure
October 23rd, 2009 at 4:09 pm

October 23rd, 2009 at 8:58 pm
Hello G1 for Life,
Skip the SPL downgrade and just goto the loading of the Dreaimg.nbh file section.
October 26th, 2009 at 12:03 am
Hi, I am trying to unroot my g1 so I can have custom themes and tether it but I am a complete beginner. So I guess I skip the first section (downgrading SPL) since I never tried to do that stuff before. When I do the second section (II. Load the DreaIMG.nbh File) I put the DreamIMG.nbh file (unzipping the folder) in the SD card (on the main folder no sub folder) and when I turn off the phone, turn it on and get to the rainbow screen (by holding end + camera) it has a white rectangle inside the green part and it says serial0. Please help me with this, I’ve been stuck on this for a few hours and I accidently deleted all my phone contacts.
October 26th, 2009 at 10:57 am
HelpMePlease,
You need to unzip the dreaimg.zip folder first and take the dreaimg.nbh file from inside it and put THAT on the SD card. Then boot into bootloader and continue.
Good luck!
If you have any other issues, please post them in the Technical Support Forum for your phone in our Forums.
October 27th, 2009 at 3:37 pm
please, okay i want to get hero on my phone. i am on step 2 and i have the same problem as HelpMePlease and i did un zip it before i put it on and it still wont work i tryed the first step and it went to this screen with a phone and a caution sign not an uploading sign help me!
October 27th, 2009 at 3:47 pm
hey the unlocker how are you ok so i want to start freash on my g1 i downloaded the file i renamed it put the whole file on the sd card held home and end and tryed to whip it out but nothing works
October 27th, 2009 at 4:04 pm
Dang,
You need to skip the Load the SPL section. Skip it entirely.
Then goto the load the Dreaimg.nbh file step…
October 27th, 2009 at 4:06 pm
Hello Detroit313,
Skip the SPL part. Just put the Dreaimg.nbh file on the sd card (make sure you unzipped it first if it is a .zip) and make sure it is not in any folders and it is named EXACTLY dreaimg.nbh and then boot into bootloader (holding down camera and power, NOT home and power). Good luck!
October 27th, 2009 at 5:15 pm
okay i did what you said and turned it on with the camera button and end button and came up with that rainbow screen then went to the white screen said loading… and it said no image file! and it said it real quick and went back to rainbow screen? please help me thanks!
October 27th, 2009 at 7:11 pm
Hello Dang,
You are on the right screen now, but the no image found means that you do not have the .nbh file on the sd card (not in any folder, taken out of the .zip folder if it comes in and renamed properly; dreaimg.nbh for G1, sappimg.nbh for mytouch).
October 27th, 2009 at 8:25 pm
I downloaded the Cupcake update to my laptop now which one do I put on my SD Card?
There is:
boot.img
check_prereq
radio.img
October 27th, 2009 at 8:28 pm
or I could go to 2 folders called:
META-INF or system?
thanks
October 27th, 2009 at 9:21 pm
hey unlocker i need ya help on going back to cupcake or just going to start fresh i downloaded rename the files and held home an end but nothing happened
October 27th, 2009 at 9:54 pm
I am trying to root a friends G1 (completed mine successfully and am running Cyanogen’s newest ROM) and am having an issue. Followed the instructions to the letter but when I try to boot into recovery mode after placing the original spl (and renaming to update.zip) along with the dreaimg.nbh file (pulled from the downloaded zip file) I just get the yellow exclamation mark in the white triangle screen…holding longer does nothing. I use Alt + L to see the text but when I choose Alt + W it just reboots…when I try Alt + S it starts installing then after “Verifying update package…” it shows E: No signature (5 files) and then E:Verfication failed and Installation aborted. with “Press Home+Back to reboot” at the bottom…
Can you help me???
October 27th, 2009 at 10:45 pm
Coolkid14,

November 13th, 2009 at 1:34 am
I copied both files to the root of the sdcard. Renamed the original spl update.zip and just wiped and applied the new updated.zip Followed the directions as above and when I got to the rainbow screen it did read serial10. I removed the battery at that point and rebooted the phone. The g1 stayed on for about a minute and then the flashing android appeared. It booted up just fine. Thanks again for these excellent instructions.
November 13th, 2009 at 6:46 am
Hi i have tried to un root my g1, i have followed all the steps but wen the rainbow screen pops up to load the dreaming nba file it says checking then NOT ALLOW! i Have tried loading the dreaming file for the link and have done this step around 15-20 times and still no look can you please help me asap as my phone need to go back! thanks Andy
November 14th, 2009 at 11:24 pm

November 15th, 2009 at 2:44 pm
So..
I wasnt reading correctly.. and I installed the G1 SPL to my mytouch.. stupid.
Is there any hope for my mytouch? It wont turn on, the led lights work.
November 15th, 2009 at 7:56 pm
On step III “Get back to cupcake” I download the file, rename it Update.zip and when I continue it errors saying a file is corrupt. I have downloaded it three time and all three times I get the same error when I try to update the phone. Has anyone experienced this? Is there another place that I can download the Cupcake update?
November 16th, 2009 at 11:48 am
hi im new to all this type of stuff im not really into technology but i really want to root my phone and i just dont know what to do for the zip file i dont know how to unzip it and i dont know what to download can anyone help me out PLEASE!!! thanks
November 16th, 2009 at 9:19 pm
dear Unlockr, after I turn the g1 on with the camara and power button it says loading, then quickly flashes NO IMAGE FILE, then start up. So when I check what version I’am on it says DRC83 not RC29. HELP?
I also downloaded both files
November 17th, 2009 at 1:30 am
Dear unlockr, I got the my phone now back to RC29.I had to format sd card, but now it wouldn’t let me install the cupcake file? it says “Can’t open/sd card/update.zip (no such file or directory) any suggestions??? please
November 17th, 2009 at 10:45 am
Jay,
The file is in the wrong place or named incorrectly. Double check that it is update.zip and not update.zip.zip and that it is on the SD card but NOT in any folders on the SD card.
November 19th, 2009 at 7:12 pm
so i have not done anything to my phone since i bought it and i am current to where a stock g1 should be…does that mean i can ignore step 1 ?
November 19th, 2009 at 7:18 pm
Ryan,
Does the G1 have Donut on it? Android 1.6? If so then you need to use this procedure to downgrade back to 1.5 and then you can go to the How To Root in One Click procedure and to the How To Load a Custom ROM procedure.
November 21st, 2009 at 6:59 am
I INSTALLED THE 1.6 UPDATE A WHILE BACK AND IT TOOK AWAY MY ROOT ACCESS I TRIED TO DO THIS AND EVERY TIME I TRY TO DO IT IT SAYS INSTALLATION ABORTED I WANT MY PHONE TO BE JAILBROKEN ONCE AGAIN SOMEONE PLEASE HELP

November 26th, 2009 at 12:28 am
I NEED HELP PLEEAASSE!
So i did everything above.
When I downloaded the DREAIMG.nbh it came as a ZIPPED File so What I basically did was open it and saw that there was 2 DREAIMG.nbh in the folder and didnt know which one to put in so i put both in. Then When I too the USB out my phone and turned it off and did All the STEPS with the “ORGINAL SPL” I rebooted and Held “Camera”+”Power Button” Then I did the “Update” and waited for to load. Then when it was done loading it said “FILE UPDATE UNCOMPLETE” or that i couldnt follow through with the update
!PLEAAASSSSEEEEE HELP ME!!!
November 27th, 2009 at 4:41 am
omg i need so much help!! my g1 said failed when i was updatin the dreaIMg. and now is stuck on the rainbow screen idk what to do please help!!
November 27th, 2009 at 7:37 pm
for some reason i add the ZIPPED folder to my sd card.. and wen i do the restart to actually open the package it says it can’t be opened, or update.zip is not found or something.. can u tell me how i get my phone to recognize the zipped folder
November 27th, 2009 at 11:17 pm
MrJackpot,
Please read the reported issues at the bottom of the procedure.
This issue is usually cause by the update.zip file being misnamed (like update.zip.zipj or if the file is not in the right place on the card. It must be on the sd card not in any folder, just on the sd card itself.
November 28th, 2009 at 10:44 am
Hello mr Jackpot i ran into the same problem as you did. Do not rename file update.zip only “update” bc the file is already categorized as “.zip” do this and you will have no problems.
November 29th, 2009 at 8:21 am
Ahh the little things you fail to miss haha. Thanks a lot Gyo. They should really fix it to say that in the instructions .
November 29th, 2009 at 6:48 pm
If you are still having issues running the dreaimg.nbh i advise unmounting sd card and formatting to erase all info on sd, then put dreaimg.nbh onto sd which may require arranging on in sd file by size. then follow the steps to loading the dreaimg.nbh file and end button to update, it will take a few min, then hit action buttom to apply then remove battery once its back to rainbow screen. follow the google login screen once reloaded and then u can apply cupcake update .
November 29th, 2009 at 9:58 pm
As we all know they are 2 version US and UK so for those getting the error 0028002 or something like that and also Serial0 think in the end try the RC7 version http://koushikdutta.blurryfox.com/G1/DREAMIMG-RC7.zip it worked like a charm for me.
Thanks TheUnlockr for a great job.
November 30th, 2009 at 2:23 am
No image founddd!!! WTFFFFFFFFFFFF?

December 1st, 2009 at 6:06 pm
Hi,
When I try to do the dreamING.nbh file it does not work…
I did the camera and power button thing then after the bootloader and after it says checking it says NOT ALLOWED!
What shall I do?
Thanks
December 2nd, 2009 at 8:10 am
Hey, when I got to”III. Get Back to Cupcake”
I downloaded the Cupcake update and when I try to apply the install in my phone it says in yellow letters “E:Can’t open sdcard/update.zip (bad) Installation Aborted.
Help please?
December 2nd, 2009 at 4:06 pm
Tommy,
Means the file is corrupt, redownload it and try again. If it still doesnt work try to redownload it using a different computer.
December 2nd, 2009 at 9:09 pm
Every time I do the recovery method with the update.zip, when I alt+s it always says:
E: No signature
E:Verification failed
Installation aborted.
^^ Been happening to anything I try and is preventing me from getting this G1 unlocked. Please help thanks.

E:No signature (5 files)
E:verification failed

?????
December 2nd, 2009 at 9:27 pm
Faded,
Skip the update.zip step and goto the Dreaimg.nbh step if you have never rooted before…
December 2nd, 2009 at 9:27 pm
David,
Yes, but you might need the RC7 version of dreaimg.nbh I would just google RC7 .nbh and use that file instead of the one we have here.
December 2nd, 2009 at 9:28 pm
Steve,
If you have never rooted before, skip the update.zip procedure and load the dreaimg.nbh
December 2nd, 2009 at 9:36 pm
That was it! Thank you so much Unlockr – That error was haunting me!

Hi Unlockr,
I seem to be kinda stuck here.
I received a G1 from a friend who was no longer using the phone. He had it unlocked but did a wipe when he gave it back to me. I researched online to see if the phone was rooted and from what I could tell it was not, so I attempted to do your one-click-root. I was getting the error Backup Failed on step 10. I then saw your known issues part – Issue: I get backup failed or flash failed when I try to use the FlashRec progam.
Solution: This is most likely because you already have a custom recovery image (OR HAVE DONUT), please use one of the unrooting procedures to get back to the original recovery image and THEN you can use this procedure.
which is how I ended up here.
I get to the part that where I load the Original DreaIMG.nbh file. it goes through the process just fine till I get to press the action button to restart.
at that point I am getting stuck with the serial 10 error on the rainbow screen.
I have checked my MicroSD Card to ensure that it is Formatted in Fat32. I also followed the steps that Alfonso left on Oct. 17th, but still haven’t had any luck.
any help would be much obliged.
December 3rd, 2009 at 9:20 am
something else to take note.
when following alonso’s steps the phone reboots when I press Alt+w. at that point I tried holding down the power button and home and get to the recovery screen again and then press Alt+s. it looks like its going to start doing something but then stops. I am able to hold down the back button and home to reboot but still get the serial 10 error.
thanks again in advance
December 3rd, 2009 at 4:52 pm
Yeff,
I would just reformat the sd card to FAT32 (I know you said it already was but you should try to reformat it again) then skip the Wipe step and just hit Alt S and wait for it to finish.
December 9th, 2009 at 4:55 am
i keep trying to get to the recovery screen but when i hold the home and power button i just get this traigle with a ! in it. what should i do?
December 9th, 2009 at 5:14 am
Glenn,
Means you dont have a custom recovery image. Just skip that step and do the Dreaimg.nbh step.
December 9th, 2009 at 12:11 pm
ok. so how do i cupcake back?
December 9th, 2009 at 12:44 pm
nevermind i got it
December 9th, 2009 at 3:18 pm

i read all the replies..
i tried the DREAIMG.nbh file(RC7) but i still cannot continue the process.
it show the 3 colour screen…still can’t continue…fed up already..:(
December 11th, 2009 at 4:45 pm
Dx,
One issue weve noticed is that you need to format your memory card to FAT32 instead of FAT.
Plug the phone into the computer and mount the SD card then right click the sd card on your computer and select Format, then use the dropdown to select FAT32 instead of FAT.
Should be in the reported issues actually.
December 12th, 2009 at 9:37 am
TheUnlockr ,
then use the dropdown to select FAT32 instead of FAT.
what you meant DROPDOWN sir?
thx for fast reply.
December 12th, 2009 at 4:57 pm
Dx,
When you click on format on your computer, it has a dropdown box (a box that you click on and it drops down other options for you to select).
December 13th, 2009 at 2:04 pm
TheUnlockr ,
Sir,i tried to select FAT32 already.
after that i copy DREAIMG.nbh file into the memory card.
then put back to my Dream.
then i press END+CAMERA.
it got 3 colours shown on the screen
then checking..then goes back to 3colours screen and shown serial0.
what problem is that?
i followed all the step u wrote already.
December 15th, 2009 at 8:07 pm
I keep getting this error before I can even update card, if i alt+w first my phone restarts

Hi Unlockr,
just in case I buy a used G1. How can I tell if there already IS a custom SPL loaded?
December 16th, 2009 at 9:30 pm
Bodacosta,
Doesn’t matter honestly, just skip the SPL section.either way shouldnt be an issue.
December 19th, 2009 at 4:15 pm
when i try to turn the phone back on in recovery mode, i get an odd symbol of the phone and a triangle
December 19th, 2009 at 10:58 pm
Jmmm229,
That is the stock recovery image.
Skip the spl step and just load the dreaimg.nbh file.
December 19th, 2009 at 11:20 pm
TheUnlockr ,

Hello everyone,
Hopefully it can be fixed though..When I turn it on, it gets stuck on the Tmobile G1 screen. I have been reading for hours to try and fix this!! Since I first got the phone actually. It seems like he rooted the g1 to something different. When I press and hold Home and Power it takes me to this…
I just bought my phone on ebay and he sold me a messed up phone!
Android sytems recovery
The it has a list of Alt + different letters…
The Background it says Android
At the bottem it says Build: CyanogenMod v1.4 + JF
I have no idea what any of this means…I need help ASAP!!!
Also when I press power and camera at the same time it says this…
DREA100 PVT 32B
HBOOT-0.95.0000
CPLD-4
RADIO-2.22.19.26I

From what I have read and seen, that radio is the wrong radio…Most start with 1.22?
you can even email me or contact me through here! I REALLY NEED HELP PLEASE!
wesleyjones21@tmail.com
Thanks
December 23rd, 2009 at 1:59 am
Wesley,
The Radio has nothing to do with it (and it is the right radio).
He probably has a ROM that is using the partitions of the SD card (and I assume he didn’t give you the SD card?).
If he did, put the SD card he gave you with it in the phone before you turn it on, if not then you will need to do the unroot procedure on our site using an SD adapter and a memory card.
Search for it and good luck!
December 23rd, 2009 at 2:34 am
Unlockr,
Yes you are right he never gave me the memory card. He kept it, I have tried the method on this site and it doesnt work? When I press home and power it takes me back to the Android system recovery. So I still try and update with the zip thing and it says
Finding update package…
Opening update package…
E:Cant open /sdcard/update.zip(bad)
Installation aborted
I have tried everything and idk what to do. I dont want to sell this and give up on it because I know there is something I can do! If you could email me that would be great so I can go step by step to try and resolve this issue! :/
Thanks
December 23rd, 2009 at 8:13 am
Wesley Jones,
Skip the update.zip part. Just goto the Dreaing.nbh file part and you should be fine.
Make sure to read the reported issues if you come into any other issues.
December 23rd, 2009 at 10:19 am
same here i got the update ABORTED
December 24th, 2009 at 4:16 am
Hi,
I was wondering if anyone had an issue when the reverted to rc29 that when we had to sign in it wouldnt let you because it would say, google services are down, and i had waited for about a day and its still telling me the same thing.. Please help!
December 24th, 2009 at 10:52 pm
im a little confuse on the 1st one cuz i done this b4 and downgraded and went back to donut but now im trying to get the hero rom again from kingx and i also loaded the spl once do i still do it agian
confused????
December 25th, 2009 at 10:49 am
Chris,
If you are rooted and loaded a custom ROM, then you just put the new ROM on your sdcard and flash it. No need to start all over.
December 27th, 2009 at 5:11 am
So, I have an unusual and complicated problem:
I completed all the steps of downgrading the SPL fine and afterwards I went on to inserting the microSD into my computer via an adapter but it wont read. Is there any other way I can load DREAIMG or at least get back to before I downgraded the SPL, because now I cannot access my SD card through USB or adapter. I only have access to the recovery screen.
Please help soon!
December 27th, 2009 at 6:07 am
Nevermind. I figured it out.
December 27th, 2009 at 11:16 pm
I followed your steps, and it is not working for me in no way shape or form…if its not too much to ask could you shoot me an email…I just want it to go back to the old way because I have no idea what to do witrh a root g1
December 27th, 2009 at 11:57 pm
I did the 1st part and went to restart the phone in recovery mode. I keep getting stuck on the screen with an exclamation point and a triangle. When I try to press Alt+w or Alt+s it brings me back to where i setup up my gmail account. I’ve tried this several times, and I even tried going back to the original FAT format…PLEASE HELP!!
December 28th, 2009 at 12:48 pm
Fadia,
Skip the Update.zip part and just do the Dreaimg.nbh section. Before you begin, make sure to format your SD card.
Other than that, please post in the technical support forums.
December 28th, 2009 at 7:29 pm
i downloaded the cupcake update andwhen i press ALT+L and ALT+S it says update cannot be found crap or watever? last time i waited fot the OTA update and it brought me back to 1.6 software? what do i do???? please help!!!!!!!
December 28th, 2009 at 7:57 pm
Jacob,
First off, calm down lol
Now, you need to make sure the update.zip is on the root of the SD card and NOT in any folder. And also make sure it is named update.zip NOT update.zip.zip etc.
Good luck!
December 29th, 2009 at 12:18 am
do i have to unzip D” cupcake download or just straight away dump to root of SD and rename? Mine has D” same prob as jacob.
December 29th, 2009 at 12:23 am
i’ve tried unzipping first and not unzipping but i’m still getting D’ same thing! BTW i’ve not rooted it before!
Please help been trying for days to root this. It’s a stock 1.6 version [newly purchased]

December 29th, 2009 at 12:05 pm
Cheston,
Read the procedure
If you are on a stock donut phone skip the SPL part of this procedure. Just goto the Dreaimg.nbh section and load that.
December 30th, 2009 at 10:02 pm
unlockr ,
i’ve got everything done . Rooted and all but all of the ROMS abort instalation
December 31st, 2009 at 1:56 pm
Shonan,
Do you get the custom recovery screen when booting into recovery? If not, then read the reported issues under each procedure and try again.
January 4th, 2010 at 9:57 pm
on the last part for the cupcake update…if u have trouble with it dnt write .zip just rename it update
January 6th, 2010 at 4:45 am
ummmmm, i was doin all the steps and when i was done load the spl, it was stuck at the stupid g1 screen. nothing will work someone the unlockr please help.
January 6th, 2010 at 10:32 am
Hi Unlockr,
Firstly you rock, Ive used your tutorials on my gf’s dream and they worked nicely. I have now bought myself a dream on ebay which has firmware 1.6 donut on it – which leads me to this thread to unroot the phone. I tried updating to the original G1 SPL and I get:
E:No Signature (5 files)
E:Verification failed
Installation aborted.
Needless to say I dont have root.
I try doing the nbh and I get the rainbow screen for a second followed by the grey screen which ends up saying “0020080 not allow” and then it cuts back to the rainbow screen.
I have redownloaded the file multiple times, and I know it was a fine copy to begin with as it worked on my gf’s phone.
I have reformatted the sd card to fat32 several times now using as many different methods as i can think of (ie via card reader, via mounting the card onto the computer while its in the phone, from within android etc).
Any clues?? I seem to be completely stuck… I read things about gold cards however I can’t find any tutorials for them which don’t require a legit version of qmat which I’m currently waiting on a puchased serial number for.
January 6th, 2010 at 1:33 pm
Anthony,
Thats normal, just put the dreaimg.nbh file on the sd card and goto the next steps.
January 6th, 2010 at 8:46 pm
I fixed my issue by purchasing the full version of qmat, using an old Windows Mobile device I had lying around and following the instructions here: http://forum.xda-developers.com/showthread.php?t=485364 to create a gold card sd card. I was then able to install the rc29 nbh file via the boot loader.
January 7th, 2010 at 12:00 am
Can anyone please help me, I followed the video instructions exactly as told, i copied each file over 2 the sd card formatted to FAT32 (not in any subfolders) but when i hold the home key and power button like in the video the triangle with exclamation point comes up not a bunch of codes like in the video…i dont know what i did wrong?
January 7th, 2010 at 12:41 am
Unlockr
i had a G1 before and successfully rooted it but now i have a new one and having proplems.
i successfully got to the Recovery Menu
but here is where i think im messing up.
i stay on the menu and Apply the HardSPL file, then wipe DATA, Apply Radio 2.22.19.261, then wipe data and partition memory card and put the Custom ROM(CM4.2.8.1) and then click wipe again then restart my phone and gets stuck on the G1 Page. i restarted my phone and went to that menu where you have to hold the Camera and Powe button and its like 3 Androids on Skateboards. anything u can help me on?
January 7th, 2010 at 3:00 pm
Damian,
Skip the SPL section and just do the Dreaimg.nbh section.
You should be holding Camera and Power, not Home this time.
January 7th, 2010 at 3:04 pm
DJToonJr,
First thing, what procedure are you trying to do? You mention HardSPL and Radio but this is the unrooting procedure…
January 9th, 2010 at 4:59 pm
Unrooted g1 just wanted to know how long it’ll take b4 id receive the ota update? Running on rc29 checked terminal emulator says permission denied so I believe I’m not rooted. Thanks..
January 9th, 2010 at 5:01 pm
Nedhaiameerah,
Update manually to Cupcake using this procedure, then wait for Donut.
January 9th, 2010 at 5:33 pm
thank you. will wait for donut. but there is no exact eta?
January 9th, 2010 at 6:07 pm
Ned,
No, if it takes more than a day, just call T-Mobile Customer Care and tell them you never got the Donut upgrade and ask them if they can send it to you.

error 00028002
Serial 0
help please?
January 10th, 2010 at 1:37 am
also i get the not allowed thing.
January 10th, 2010 at 2:29 pm
Edric,
This happens sometimes. You need to pluf your phone into the computer and mount the SD card. Then right click the SD card on the computer and reformat it to FAT32 instead of FAT. (Caution this will erase your SD so save everything on it to your computer beforehand). Then put the dreaimg.nbh file back on the SD and back into the phone and try again.
January 11th, 2010 at 10:49 pm
yeo. when i try to install the update.zip its says”theres no such file as update.zip” something lik that. do i have to wait untill i get the update??
January 12th, 2010 at 1:33 pm
Raphy,
Skip the update.zip section. Just do the dreaimg.nbh file.
January 15th, 2010 at 4:41 pm
I downloaded DREAIMG-RC29.zip. When I try to unzip, it asks for a password. What is the password?
Thanks!
January 20th, 2010 at 3:00 am
hey guys, who ever is doing step III, which is getting back the cupcake, when you download the zip file and copy it to the sd card RENAME THE FILE “UPDATE” NOT “UPDATE.ZIP” because is already a .zip file you dont have to write .zip at the end of the file…….. hope this help it did for me……….
January 20th, 2010 at 1:46 pm
Can someone explain to me when you get the g1 out the box what does it come wit cupcake or donut and what’s the dif? I’m confused thinkin cupcake is the best then donut better. Which is really which?
January 20th, 2010 at 2:26 pm
Ray,
Good point. If your computer hides the .zip extension (which I believe most newer version of Windows do now), then just rename it to update not update.zip (as it doesn’t show you the .zip in the first place so you would be renaming it to .zip.zip)
January 20th, 2010 at 2:28 pm
Skanks,
New G1s come with Donut (Android 1.6) and old ones had Cupcake (Android 1.5). You can google the differences but its just a few minor things (voice search was a nice addition).
So Cupcake (1.5) then Donut (1.6) then Eclair (2.0, 2.1) and then Froyo (??).
As simple way to know if a version of Android is older or newer, they go alphabetically
January 23rd, 2010 at 8:31 pm
Hi i am running 1.6 not rooted from t-mobile but i want to root ot HOW!!! i have ooked at all you steps and none of them work
January 24th, 2010 at 2:26 pm
John,
They work for all the people that hit this site just fine. You need to look for our How to Root a Donut phone procedure and follow the steps exactly.
Good luck!
January 27th, 2010 at 6:23 am
Hi, I had my phone rooted, and i watched your tut on getting a rom to work using your 1 click method, you said that if I didnt have the options you had that I had to unroot and then root again using your method. So I then started to unroot, but now I am stuck at the dreamimg.nbh part.. i have get to the rainbow screen, then it goes to the gray screen and says checking.. then it says not allowed.. then it goes to the rainbow screen again with seria 10. I have no idea what to do now. I have a tim dream from Itali if that makes any difference.
Please help I have spent all night trying to figure this out.
January 27th, 2010 at 7:29 am
Hi Unlocker,
i have successfully root and unroot with the steps on ur site, however my phone was send to service and it came back with a 1.6 donut.
1. now i saw that you have a session that able to downgrade to 1.5 cupcake, but when i try the first step with is to update the SPL, but this step cant be done unless i have a root where now i don have.
2. Load the DreaIMG.nbh not able to work even i have format my memory card as per instruction, as it says not allow.
3. the last step don need to mention as i do not have root to update to cupcake.
seems like this steps don work for some of us i wonder if getting root access have to downgrade to 1.5 or can we jus do it on 1.6
if 1.6 is not possible then the steps on this site doesnt help me.
Unlocker please help us thanks.
Raymond
January 27th, 2010 at 1:43 pm
Raymond,
Read the procedure. You only need to downgrade the SPL if you upgraded it. Since you have a stock phone skip that section.
You do not need root access to downgrade to get root access (that wouldnt make sense lol).
Good luck!
January 27th, 2010 at 1:44 pm
Bjessle,
Read the reported issues.. your solution is there.
February 6th, 2010 at 5:01 am
Wow! I LOVE THIS! I was experimenting with rooting, since all my friends said it was the greatest. I rooted with Cyanogen, and I hated it. And so when I tried to unroot, all the guides were so confusing. (tbh, so was this, but not nearly as much haha) but the video made it sooooo easy! Thanks!!!!!
February 6th, 2010 at 5:04 am
Sorry, I meant to put this in with the earlier post; can I delete the dreIMG.nbh off of my SD card? Or do I have to leave it on indefinitely? (same with spl.zip) sorry if those are horribly dumb questions, this is all new to me lol.
February 7th, 2010 at 9:55 am
Hello I was just trying to root my G1 but I stucked during the wipe process . My screen looked different than in the video and everytime i was pressing alt+w the phone just tried it for a secand an then reboot without wipe and all my datas were deleted .
February 8th, 2010 at 7:52 am
Here’s an issue…
Every time I turn on my phone it goes to the rainbow screen, flashes “No image file!” then back to the rainbow screen “Serial0″. The problem with this is that I unrooted and loaded Cyanogen months ago. If I start with home+end I can get to the system recovery screen, but I can’t access my SD card to load dreaming.nbh on it. The reported issues talk about problems while unlocking, but what about a problem after it’s been working for months? Note: I haven’t made any changes to any files in several months.
February 8th, 2010 at 1:22 pm
Justin,
The serial issue happens when the SD card is not formatted correctly. Read the reported issues below the procedure.
February 8th, 2010 at 4:20 pm
The SD card is formatted as FAT32. It was all working fine as a rooted phone until suddenly this error started. I followed your instructions to reformat and have worked to unroot the phone, in case there is a problem with it I can bring it in. However, I still get stuck. I get all the way to the part about DREAIMG.nbh (it does recognize the file and can load it) and it says “Press power button to start update image” but then the phone becomes unresponsive. No button works. It always freezes at this screen.
February 9th, 2010 at 8:14 am
