Checking your G1 every other minute to see if RC33 has been beamed down upon you? Welcome to the club. Fortunately, you don’t have to wait to join. We got an email yesterday (Thanks Peter) with a link to to the most recent firmware update, version 1.1 and RC33. Here is a direct link to the file:

We didn’t spread the word soon enough but it appears the rest of the interwebz did and as everyone else proclaimed, PROCEED AT YOUR OWN RISK. UPDATING MANUALLY IS NOT ENDORSED BY PHANDROID AND COULD BRICK YOUR PHONE AND VOID YOUR WARRANTY. That being said, if you’re a rebel and want to dive into the deep end, MobileCrunch provided an excellent guide to updating manually that we’ve pasted below:

Note: You must currently be on RC30 for this to work.

Mandatory warning: Updating firmware can be a delicate procedure, so continue at your own risk. Always back up everything. Make sure to check the hash or otherwise verify a firmware’s source. Whenever possible, download it directly from Google (as you will in this tutorial). Make sure that your battery is charged so as to keep it from fizzling out mid-update, and that you don’t have the G1 plugged into USB during the actual update process.

1. Grab the RC33 update from Google here.

2. 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.

3. 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.

4. From the icon screen, open the keyboard and hit Alt+L. This allows you to see what’s going on during the update.

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. The G1 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. 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. Congrats!


  • Some microSD cards don’t seem to play friendly with this process. If you have trouble with one card, try another..

Links have been reportedly up and down but XDA-DEV forum has a bunch of mirrored versions you can download here.

Also, please tell me that somebody (cough anyone that has played Tony Hawk cough) understands the above picture?
