G1 Phone with Firmware RC33

Recently we had reported about latest firmware update RC 33 for T-Mobile G1 Phone. The process of rolling our Firmware to G1 phone users is very slow and there is no control over update process. You need to literally keep looking at your G1 handset for any firmware update prompt. I am sure many users are eagerly waiting for g1 firmware update.

Well don’t worry you can manually update your G1 Phone firmware to RC33. Fortunately some has extracted the RC33 from official update package which can be used to update g1 Phone firmware to RC33. Here is guide on How to Manually Update G1 Phone firmware to RC33.

The process of Updating g1 Phone firmware is exactly similar to what we had reported during RC29 update.

How to Update G1 Phone Firmware RC33

1. Download RC33 update from Google here.

2. Rename it the download file from signed-PLAT-RC33-from-RC30.f06aa9b3.zip to update.zip, and place it at the root i.e the very top directory of your Micro SD card. (If you added the file to your microSD card by connecting the handset to your computer via USB [rather than using a dedicated microSD card reader], make sure to unmount it and disconnect the USB cable now.

3. Turn off your G1 Make sure it completely powered off. Now again turn it on by holding the Home+End keys until you see T-Mobile G1 logo.

4. From the icon screen, open the keyboard and hit Alt+L.

5. Press Alt+S to begin the update. Remember, the update needs to be in the root of the Micro SD card and needs to be named update.zip.

6. Once it finishes, follow the onscreen instructions and press Home+Back to finish.

7. G1 Phone will reboot a few times to flash different parts of the firmware.

If all went well, you should now be running the latest update, RC33. Enjoy your new, shiny RC33 update, complete with Google Latitude!

To make sure all your hard work wasn’t for nothing, hit Menu > Settings > About Phone > scroll to Build Number. You should see RC33 in there somewhere.

    I updated my gphone last night but had a hard time until I realized that my son’s new computer had suffixes of file names hidden. I renamed the file “update.zip” but discovered that I had really renamed it”update.zip.zip.” If you are having trouble getting the device to recognize the update.zip file when you hit Alt S, then make sure that the file was renamed properly.
    cheers,

    First time trying this update. Works great. I was having the same problem as JRG but I figured it out the end that I didn’t really download that link that was posted. I only had a 2kb zip file and I wasn’t too aware until I tried downloading it again and it was 18mb. I guess lesson to be learned is read twice if you still don’t get it, read again. Thanks guys for the help.

  • TOWNONE1

    Hey whats up everybody I was totally having the same problem with it not recognizing the file!!!!! NAME THE FILE —UPDATE— not update.zip! .zip is the type of file no need to let the phone know that! Doing my update now, cant wait! Thanks G1′ers

  • Charles

  • EB

  • oscar

    hey mine keeps on failing in the middle could you please help me

  • jeff

    Have you tried to download a new copy of the upload file? Maybe it is corrupt.

    The phone reboots several times in the process, are you waiting long enough? I wiped my sd card before copying the update file onto it as a precaution. I doubt it is necessary but may help. Simply copy all files on your sd card to your computer, reformat the card by right clicking on it and selecting the fat reformat option, then copy only the update file onto it, and go through the process. These are my best guesses.

    Has anyone tried this on the Developer version of the phone? Any issues or should it work the same? (On 3 in Australia)

  • Bill

    Just tried this several times.

    The G1 reports that there is afailure in line 1 and aborts. I have downloaded five or six times, wiping the sd card each time, same result.

    I’ve noticed my phone is RC8 – and its new too! Do I need another update prior to this or something? It just won’t take 29 or 33.

    Thanks
