How To: UnRoot Your T-Mobile G1/Get Back to Donut

THIS PROCEDURE IS OBSOLETE! PLEASE DO OUR NEW HOW TO UNROOT PROCEDURE:

HOW TO UNROOT THE HTC G1 / DREAM

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. 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.

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.

II. Get Back to Cupcake (Android 1.5)

1. Download the Cupcake update from here, then put it on your SD card (do NOT extract it, just move the .zip file to the sd card, NOT in any folders) and rename it to update. Then turn off your phone and turn it back on by holding down Home and Power and keep holding until you get to recovery mode. In recovery mode (the ! screen) hit Alt L to see text, then hit Alt S to Apply the update.

III. Get Back to Donut (Android 1.6)

1. After you have gotten back to Cupcake (Android 1.5), download the Donut update from here, then put it on your SD card (do NOT extract it, just move the .zip file to the sd card, NOT in any folders) and rename it to update. Then turn off your phone and turn it back on by holding down Home and Power and keep holding until you 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.

  1. Original SPL
    Original DREAIMG.nbh where can i get these files it says download these 2 files but you cant from this page

    1. 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.

  3. 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).

  4. 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………

    1. 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.

    1. 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

  6. @ 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.

  8. Im tryin to do this, but it keeps sayin no image found and i dont understand. I did everything right!!

    1. Hey Shaud,

      Make sure that you have the DREAIMG.nbh file on the topmost folder of the SD card (not in any subfolder, should be there as soon as you open the SD card on the computer, make sense?) then try again.

  14. 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

    1. 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.

  16. 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….

    1. 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).

  17. 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?!?

    1. 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?

  19. 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

  22. 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?

    1. 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).

  23. 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.

    1. 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.

      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 🙂

  28. 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?

    1. 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?

  29. 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?

  30. 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.

      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).

  37. 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.

    1. 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.

  38. 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 🙂

  39. plz i have problem in root my g1

    plz helpe me

    1. 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).

  40. Hmm still very odd the G1 is still loading onto the Cyogenmod recovery screen even after trying a wipe and install.

  41. 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?

  43. 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

  46. 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?

    1. 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.

    1. 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.

  49. same problme again and when i put th SPL and install it the phone give me

    E: verification failed

    and my problme the unroot wil helpe me or not
    Plz help me and thanks for your answer

    1. 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.

    1. 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.

  58. Hello!

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!

  60. 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.

  66. 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?

  70. 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

  71. 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!

  74. 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!

  75. 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?

  76. 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.

    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)?

  100. 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.

  110. 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.

  111. 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.

  122. 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

    1. 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?

  123. 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!

  126. 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

    1. 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).

  127. 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.

    1. 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.

  138. 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!

    1. 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.

  142. 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????

    1. 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

  147. Can't get cupcake back

    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.

    1. 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.

    1. 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.

    1. 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.

  164. 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

    1. 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 🙂

  165. 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

    1. 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….

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)?

    1. 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!

  180. 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

    1. 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!

  182. 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…

  183. 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?

  186. 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!

    1. 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.

  192. 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.

  196. 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.

  202. 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?

    1. 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.
