So, you are still waiting for the new update (RC33) to show up, remember that is the update that was rolling out sometime between February 5 and February 15. Hey, that is a long time and we can be just as impatient as anyone else. Thankfully we have found some instructions that will force that update.
Of course, this post comes with a nice warning, proceed with caution and don’t blame me if something goes wrong in the process. In other words read the directions carefully, take your time and if nothing else, make sure your important data is backed up before you begin.
So, if you are still willing to proceed, to begin with make sure you have your microSD card handy and then download the RC33 update from Google. After you have both of those ready just follow the directions below and you should be playing with RC33 in just a few minutes.
- Rename it from signed-PLAT-RC33-from-RC30.f06aa9b3.zip to update.zip, and place it at the root (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.
- Turn off your G1, then turn it back on by holding the Home+End keys until you see an icon popup after the T-Mobile G1 logo.
- From the icon screen, open the keyboard and hit Alt+L. This allows you to see what’s going on during the update.
- 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.
- Once it finishes, follow the onscreen instructions and press Home+Back to finish.
- The G1 will reboot a few times to flash different parts of the firmware.
Now, just to double check and make sure the update was correct, go to Menu -> Settings -> About Phone and then check the Build Number, it should refer to RC33.
