How To: Root the HTC G1/Dream

THIS PROCEDURE IS OBSOLETE! PLEASE DO OUR NEW AND EASIER HOW TO ROOT PROCEDURE INSTEAD:

HOW TO ROOT THE HTC G1 ANDROOT METHOD

I. Before You Begin

1. This works on all G1’s and Dreams

2. YOU MUST DO THIS WHOLE PROCEDURE AND THEN DO THE NEXT ONE ON LOADING A CUSTOM ROM TO GET FULL ROOT ACCESS!

II. Downgrade to Cupcake

1. Download the Original DreaIMG.nbh and the Original Cupcake update.zip:
Original DREAIMG.nbh
Cupcake Update.zip

2. Plug the phone into your computer via USB. Select Mount by pulling down on the notification bar at the top of the phone’s screen and selecting the USB notification. You should now be able to access the sd card in your phone on your computer.

3. Now, put the DreamIMG.nbh file and the update.zip (do NOT extract the .zip file, leave it as a .zip file) files that you just downloaded on the root of the SD card (NOT in any folder, just on the sdcard itself).

4. Unplug the phone and turn it off.

5. Turn on the phone by holding the Camera button and the End key until the bootloader screen comes up.

6. Hit the End key to start the update. DO NOT INTERUPT THIS PROCESS.

7. Once it is done, hit the trackball to restart the phone. You now are on the stock firmware RC29.

8. 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 (the ! screen).

9. In recovery mode, slide out the keyboard and hit Alt L to bring up the menu, then hit Alt S to Apply the update.

10. Once the phone reboots, go through the normal setup process to get to the home screen.

III. Flash a Custom Recovery Image

1. On your phone, goto Settings, Applications, and make sure Unknown source is checked ON.

2. On your phone, goto Settings, SD card and phone storage, and click Unmount SD card.

3. Then click Format SD card (it should automatically remount after this).

4. Plug the phone into the compuer via USB, then pull down the notification bar and click on the SD card notification. Then click mount.

5. Download this APK and the recovery image and save it to your computer:

FlashRec.apk

Amon Ra’s Recovery Image

6. Once they are saved to your computer, copy them both to your SD card (do NOT put them inside any folders on the SD card, just put them on the SD card itself).

7. Unplug the phone from the computer once they are downloaded to the SD card.

8. Goto the Market and download Linda File Manager or any file manager program if you do not already have one.

9. Open the file manager and goto SDCard and then find the FlashRec apk file and click it. If asked tell it to use Package Installer to open it. It should automatically install the apk.

10. Open the FlashRec program and click on Backup Recovery Image and wait for it to finish.

11. Once done, click on the empty text box in the FlashRec program and type:

/sdcard/recovery.img

Then click on the Flash Custom RecoveryImage button and wait for it to finish.

12. Turn off the phone and turn it on into Recovery mode by holding down Home and Power to turn it on (keep holding until the recovery screen comes up has a bunch of text on a black background). So long as that screen comes up, LEAVE IT ON THAT SCREEN, you have done it correctly and can now go on to the How to Load a ROM video below:

How To Load a Custom ROM on the HTC G1/Dream

13. To get Root access you MUST go to the next video mentioned above and load a custom ROM.

Reported Issues

Issue: G1’s are erasing the recovery image before we can load a Radio, SPL, or ROM.

Solution: Once you do step 12 and boot into recovery mode, go straight to the next video, leave the phone in recovery mode, and do Section II to load the SPL. If you turn the phone off and on before then you will have to redo these steps.

Issue: I get Invalid Recovery Image or Flash Recovery doesn’t show up, it stays greyed out!

Solution: Make sure that the spell correction and auto completion are OFF in the Text Settings (Settings > Locale and Text > Touch Input > Text Input then turn off Prediction, spell correction, and word completion) of your phone. If not then it may put in spaces where they do not belong. (I had it put a space after .img and couldn’t see it so couldn’t figure out why it kept saying invalid recovery image, like you guys).

Other than that, just make sure it is on the root of the SD card (not in any folder) and that you are typing in:

/sdcard/recovery.img

and it should show Flash Recovery

Issue: When I download the FlashRec.apk it shows up as a .zip not an apk.

Solution: No problem. Do NOT extract it, just simply replace the .zip with .apk and then proceed with the procedure.

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.

Issue:I get serial0 on the rainbow screen.

Solution:Turn your phone back on to the hone screen, the plug in the phone via USB cable and mount the sd card.
Then right the sd card on your computer and click format (this will erase everything on your card so save it all to your computer first if you want to keep it). Select FAT32 when it asks you what format to format it to. Once it is done save the file you were trying to flash back onto the sd card and try to flash it again.

  • Vylle

    Hey, the link to the cupcake update is replaced by “follow us on facebook” can you please change that? thanks

    • Vylle,

      Ha, not sure how that happened… Fixed. Thanks for letting me know.

  • mike

    your Cupcake Update.zip link takes you to your facebook signup page and not the link that I need to do this.

    I have been trying to find another rc29 out there but the two aren’t signed.

    I am getting very frustrated.

    • Mike,

      It was fixed, it takes you to the right place. As for the .nbh file it is signed and worked for plenty of people. Try downloading it using a different browser or on a different computer (it is most likely getting corrupted during download, not uncommon).

  • david

    when i do step 5…nothing happens it seems just 2 stay in a red/green/blue/white screen with the word serial10 in the green part….i hit the end key and nothing happens

    • David,

      Means you need to plug the phone in via USB (with it on) then mount the sd card and on your computer right click it and click format (choose fat32 in the drop down instead of fat) and click quick format.

      • alex

        hi unlockr,

        i found myself facing the problem of having serial0 after section II step 7. what i did was pull the battery out. for some reason, the screen is still on. i waited for my phone to die and when i replaced the battery back, my phone put me in the register screen. after registering, i checked my phone status and it was successfully rooted. i dont think you will be able to mount your sd card while you’re in the four colored screen with serial0 because the phone is completely frozen. btw, i also tried pressing a lot of buttons before removing my battery

        • DylanJ

          After successfully updating dreaimg.nbh, I press the trackball and get the rainbow serial0 screen. It says:
          DREA100 PVT 32B
          HBOOT-0.95.0000
          CPLD-4
          RADIO-1.22.12.29

          Sep 2 2008

          How do I correct this? Thank you for your time.

          • mike m

            im haveing the exact same problem how do you fix it plzz???

      • wei

        i have the same problem with step 5. i mounted the sd card with the phone on. What do I right click and format?

        • Gedy

          I still have same problem HELP PEOPLE!!!

  • Vylle

    thanks theunlockr, i have another problem.. this 1 more serious, after loading flashrec and mapping the text box to the image file on the SD. i shut down the phone but now it wont start – its stuck at the G1 screen

  • Vylle

    ok, when i boot it normally, (without trying to go into recovery mode) it works.. but now it just wont go into recovery mode.. any ideas?

  • adi

    Hi!do you know what “model id incorrect” means?(after step 6. Hit the End key to start the update. DO NOT INTERUPT THIS PROCESS.)

  • mike

    yeah, it worked after I found the rc29 on googles site.

    Now I’m running cyanogenmods newest stable rom with 5 home screens and multitouch!!!!!!!!!!!!!

    Thanks for the instructions.

  • Marcel

    Will this work on the rogers updated RUU

  • adi

    It’s HTC Dream (A7177 Italian TIM,not from T-Mobile).

  • Marcel

    Hey sorry just wanted to clarify. At the top of this page it says “This Works on all G1’s and Dreams” so does that include the Rogers Dream and if not it might be a good idea to refrase that quote

    • Marcel,

      This works on ALL G1’s and Dreams lol Just like it says.

  • jose

    hey i get the same problem as adi “model id incorrect” i just recieved this phone from rogers cuz i didnt wanna do the 911 update that rogers had so they sent me a new one that already had it… so i have an rogers htc dream, firmware 1.5, build # 1.89.631.1, hboot 1.33.0010. im not sure if that helps but i cant seem to get this right

  • Marcel

    Every time i try and power up with the camera button, it tries to load the “image” but get a message of no image or wrong images, this is on a Rogers Magic which has had the mandatory update applied to it. I have tried re-downloading the files with no success.

    Thanks for any help you can provide

  • Marcel

    do we need a goldcard? please help

  • Marcel

    Ok same result as others Model ID incorrect!

  • adi

    Marcel,did you use a goldcard?And you had the same result?

  • Fearz

    i got the sam error that David got. so can i just take the battery out and continue normally.

  • Marcel

    No I haven’t tried a gold card yet, had to go to work. Maybe in a few hours. If I have any success ill report back. If not I would see this as a waste of time for us Rogers updated phones

  • adi

    I tried goldcard…nothing.But I have a friend,he helped me.Sorry!I HAD a friend…and an HTC G1 🙂 …if it will boot sometime, I’ll come back… ;(

  • Ed-

    For those who got the David issue: format the SD before the 1st step(copy the dreamimg.nbh and the cupcakeupdate.zip) then retry.

    I got the same but now my G1 is flying with the superD 1.11!!!

    Thanks to TheUnlockr for these easy root system!
    Some clicks on your ads is the minimun!!

  • Marcel

    Seems a gold card will only bypass the CID (carried ID) and will have no bearing on the model ID. I think were stuck unless HTC has another leak 🙂

  • Mano2323

    I put the nbh. file and the update file on a formatted sd card and then in the phone. I held down the camera+power button and it successfully flashed the nbh file. I then powered down the phone and held power+home button to get into recovery mode. I pushed alt+s and it started to flash the file. it got done and it went right back to that “three color screen.” now every time i restart the phone it goes directly to that screen. I was told that if your reflash the nbh file it’ll fix it but i keep trying that and it keeps going to the color screen. PLEASE HELP! What am i doing wrong????

  • jose

    so no ideas for the rogers htc dream with the new mandatory update they had

    I have put the DREAIMG.NBH and the update.zip file in my root folder and did everything that was asked. For some reason I keep getting “image not found” and stuck on the multicolored screen. My SD card is Fat32 and the files again are in the root directory (not in any folders). Does anyone have a fix for this or may know what is going on? I would greatly appreciate any assistance in this matter.

    • Jamiel,

      Try reformatting your card then putting hte file back on the SD and trying again.

  • Jamiel

    TheUnlockr,

    Thanks for the tip. I had formated the SD through windows but not through the phone. Once I formated through the phone it worked like a charm. I cant believe I spent 8 hrs doing everything but formating through the phone. De-Da-De!

    PROBLEM is activation with wifi only works on rc29!
    PLEASE HELP! THanks

    • Jimmyk,

      You can downgrade to RC29 and use our How To Activate the G1 without a Data plan procedure.
      OR the easiest way is to just add the data plan to your account for the a day and remove it (literally will cost you $1 for the day). Also you can just borrow a friend’s SIM that has a data plan too, then sign in and put your SIM in after.

    so from the looks of it this doesnt work on the htc dream with the lame rogers 911 update? i suppose that would explain a lot of my other failed attempts 🙁

    I got to step 5, but when i got onto the rainbow screen, i got 00028002 and “not allow” on the grey screen then:
    DREA110 PVT 32B
    HBOOT-0.95.0000
    CPLD-4
    RADIO-2.22.19.26I

    Sep 2 2008

    and then “Serial0” later down, in a white band thing.

    I’ve searched around and found lots of similar problems, but none had solutions.
    I formated my sd card to FAT32 and tried it again with no luck.
    any idea what to do?????

    • Basil

      Same exact problem, except my line of RADIO reads, 1.22.12.29 Tried reformatting the sd card multiple times, but always get the same result.

  • ohd

    a few extra bits.
    my build number is DRC92 if that helps with anything…

  • My solution to the serial 0 problem.

    I have a tmobile G1, came to the serial 0 on the rainbow screen. Could not turn the phone off. could not access the sd card with the usb cable.

    I took the back off the phone and pulled out the battery to shut it down… put the battery back in and started the phone. It booted up to the setup screen, so I turned it off again, and this time followed the instructions again from step 8+

    Hope that helps 🙂

      this worked for me.

    • IceMan

      I’m using a Mac and for some reason, the file was named DREAIMG.nbh.nbh
      Tried formatting the card using the mac and it wouldn’t do FAT32, put in PC and no luck, finally formatted with G1 and it successfully formatted to FAT32. Tried again and stuck on Rainbow screen still. Changed DREAIMG.nbh.nbh to DREAIMG.nbh and it finally worked.

    After following all of the steps, I have loaded up Cyanogen Mod 5.0.8-DS on my T-Mobile G1 & it is working great. First of all, thank you so much, awesome info & great instructions! I’m just wondering if now when you say we can change Mods anytime now after all steps have been done, “IF I GO TO G1 MOD DOWNLOAD LINK, CAN I NOW JUST SAVE THE G1 FILE OF ANY MOD ON THAT PAGE & LOAD IT UP ON MY PHONE, OR ARE THERE OTHER STEPS THAT NEED TO BE DONE?” IS THE RADIO & SPL ALL GOOD NOW FOR THESE OTHER MODS ON YOUR G1 MOD PAGE?”
    THANK YOU. WANTED TO CHECK OUT ANOTHER MOD ON YOUR SITE, BUT JUST GOT ALIL CONFUSED WHEN I WAS READING THE INFO FOR THE MOD. rusty804@gmail.com

    • Rusty804,

      Once you have the SPL and Radio flashed you can leave those as they are (most of the ROMs will run with those just fine). Just put the new ROM .zip file on the sd card, boot into recovery, wipe data, and flash the new sd card.

  • Daniel Chavez

    I was just wondering on your new video posted 10 months ago on you tube, where you can root your g1 or my touch you had said to download 2 files, one called FLASHREC.APK, and the other was AMON RA’S RECOVERY IMAGE, where can i find these,(I have a G1). thank you

    To everybody suffering from the Serial0 curse… my comp wouldnt let me format my device when the phone was plugged into my computer, so I had to grab a mini-sd to memory card adapter and plug it into my comp, then I was able to format it and plug it back into my phone. Good luck.

    Thanks for such detailed info. I was trying to follow instructions elsewhere and I got as far as downgrading the phone (works as Android version 1.0) and I thought I rooted the phone as the next step, but now when I try to boot to recovery, I just end up at the bootloader (rainbow)., At least that’s what I think it’s called.
    Is it ok to just start over again from your instructions, or do I need to do anything special first?

    Everytime I use the links you provided that I must download first it goes to a website titles megaupload http://www.megaupload.com/?d=NAAS5VBS, but it only offers games. (That is for the DREAIMG.nbh file.) And also for the Cupcake Update. I am a noob please tell me what I am doing wrong. Is there any other place I can find these files?
    Thanks in advance.

    Anyone with advice can mail me @ jp.miller850@gmail.com

    • Jon,

      That site is a file hosting site (and they are all a little busy to look at). Just look at the top right of that page and it’ll tell you to enter in a couple of characters and press the button to download the file, then it’ll make you wait a minute or so and the download link will appear and you can download it.

    10. Open the FlashRec program and click on Backup Recovery Image and wait for it to finish.

    Can not run command. And this is strange, because I’ve rooted this phone before. Unfortunately it returned to be un-rooted again 🙁

  • Zach

    I had the same issue as David, where the bootloader screen would stay up without anything happening. I followed the instructions to reformat the SD card on the computer to Fat32, but upon clicking “Format…”, the drive would disappear, with a notification saying that “Removable Drive does not exist”, and the SD would be automatically unmounted.

    A quick google search created a few results on the subject, but most solutions revolve around inserting the SD into an external reader, something that I do not have available. The one “solution” I did attempt was reformatting the SD on the phone itself, so I backed up the card’s contents and tried that, but it did not let me choose to format it as Fat32, and the initial problem of formating via the computer still exists.

    Any ideas?

Now, if i root/install a custom ROM will it ask for log-in procedures (with WiFi deactivated)…if yes, can i redo the same procedure to activate my G1 without a data plan as shown in ur videos :), or am i stucked in my stock G1 🙁 Thanks

    • Eri,

      Most custom ROMs, the developers have added a “Setup Later” option to that login screen, which allows you to get to the homescreen and then turn on Wifi before you setup so you should be fine. Just use a popular ROM.

    Hey there. I downloaded all the required files, but when I get at the bootloader screen, it checks for the file, but it says : Not allowed

    What did I do wrong?

  • Dear Unlockr,

    I have followed every step of the procedure “How To: Root the HTC G1/Dream”, but I failed to reach the Recovery Mode. I even failed to load the downgrade to Cupcake (Android 1.5 right?).

    My guess was that since my HTC Dream already runs on Cupcake (Android 1.5 right?) I did not need to downgrade. Therefoore I started the whole procedue again, but I skipped “Downgrade to Cupcake” and I jumped to “Flash a Custom Recovery Image”.

    I dowloaded the files you recommended (FlashRec.apk and Amon Ra’s Recovery Image ) as well as the Linda File Manager from the Market. Based on you video, it looks like step #10 and #11 have been completed successfullu, but when I try to complete step #12 I do not reach the Recovery Mode.

    I am clueless. Can you help me root my HTC Dream in order to install Android 2,2 Froyo?

    Thank you very much for your help.

    • Pierre-Jean,

      1. Go to Settings > About Phone and look for Firmware. Does it say 1.5 or 1.6? If it says 1.6, you need to do the procedure from the beginning.
      2. Does it say Successfully Flashed in the FlashRec program? If it does make sure you turn off the phone, then turn it back on by holding down Home and Power at the same time and keep holding them until the recovery screen comes up.

    is it possible to do this on the Rogers network in Canada?

  • Is there any alternative to pressing ALT+L and ALT+S? I can’t use the keyboard due to modification I’ve made in order to keep the screen working.

    • I’m sorry Mr. Seth, but it looks like you will have to suffer with good old 1.6 until you move on to a new phone, risk killing your screen again, or somebody figures out how to do this rooting process without using ALT+L and ALT+S.
      🙁

    Ok I successfully rooted my phone to firmware 1.1, correctly installed the wifi tether app, but there are several apps on the marketplace that I can’t find now, one being handcent sms. I even tried downloading it from the internet, transferring it to my phone and then running an app installer, still didn’t work. Is there anyway I can get it??

  • Frida Escalante

    I have a couple of questions, i been wanting to root my G1 DMD64 1.6 and im not yet sure if its safe.

    so my questions are would everything be working the same after i root?
    if i mess something up would i be able to go back to my original which is DMD64 1.6?
    is this the safest way to root?

  • pat

    how do i root my phone without a data plan pleasse helpp a video wouldd help!!!!

    • Pat,

      The easiest way to do it would be to just either add the data plan for one day to your account (just add it then remove it tomorrow) – it will LITERALLY cost you $1 for a day’s usage. OR just borrow a friend with a T-Mobile SIM card with a data plan to activate the phone and then put yours in once it is activated.
      Otherwise, click on How Tos at the top of the site then Android then G1 and you’ll see a procedure for how to activate the G1 without a data plan if you want to try that, but it’s totally worth the $1 to just add data for the day.

  • pat

    but i can still root my phone without it right. i would just have to type the thing on my keyboard and use the computer /adb to get me to the wireless settings on my phone, and then activate my phone that way right, i would just have to pretty much do one extra step. also will that adb syncing thing work every time when i want to activate my phone or only just on android 1.6. and lastly is rc29 android 1.6 something different

    • CaptSasquatch

      Pat,
      You seem to be having the same issue as I am. rc29 is actually 1.0, not 1.6. The security loophole for rooting was patched in 1.6, meaning you have to downgrade in order to root. However, it seems that once rooted/updated, you have to activate the phone again. With a data plan this is not a problem. For those of us who do not have a data plan, it seems an endless cycle of downgrading/unrooting so that we can get into the settings to turn on the wireless to activate the phone. Once you upgrade to 1.6 or beyond you will not be able to activate the phone without the data plan.

      At least that is how I am understanding it.

      @TheUnLockr, Please correct me if I am wrong.

      • Sorta, but try the new AndRoot method linked at the beginning of the procedure. That should work on 1.6 without downgrading at all 🙂

  • Jared

    I think I have a major preoblem I formated and tried to root the phone and when I did that I think I wiped the phone. So when I install dreaimg.nbh and then I installed cupcake and it loads up but all I get is opening screen and no sim card the time and emergency number. But I cant do anything beyond that. I tried to up load donut but it fails at line 2. Can some one help me?

  • Datz Skinny Mini

    I followed all the steps and and I was about to backup it said “Backup FAILED:Could not run command” why is that

  • I’ve nearly bricked my phone 4 times taking stupid advice off people. Went through a plethora of roms loading them all on to no avail. Was about to give up hope and landed here. YOU ARE GOD! I am going to Georgia soon to work for a year and I bought a cheap tablet in china and its not 3g so I figured get my phone to be a wifi tether device…. Need root….. the problems began. but now you fixed it.

    ADVICE TO NEWBIES….. I WAS CLUELESS! Just follow the steps…. EVERY STEP….. WORD FOR WORD……. and your phone will be rooted then you go to the next page WHICH YOU MUST DO! then your phone will be ready for custom roms.

    These guys are lifesavers trust them!

  • Imbigsmokey

    I get all the way to II-10.  But it seems there is no radio image to allow the phone to connect to the network….so i can’t make it to the home screen since i can’t access my google acct.  

  • Hi, I did everything but when I get to Step 12 for Flashing a Recovery Screen, it says no image found and goes into a rainbow screen with “Serial0”. 
    I keep formatting the sd card on the computer because I can’t find the “Format SD card” option in the phone’s setting.
    I made I put the recovery.img into the root of the memory card but it won’t find it?
