Bored of waiting ages for the new firmware updates for your T-Mobile G1? Download and go get them yourself! It’s not easy, but you’ll be able to get it done if you pay attention to this guide from modmyGphone!
The firmware version can be checked out at Settings > About Phone > Build Number
Just to be on the safe side like all types of update, ensure the battery is fully charged, or at least above 75%.
1. Rename the archive to “update.”
2. Copy the file to the SD Card.
Note : Connect the phone to desktop and then transfer the file. Don’t use a card reader, nor should you remove the card from the G1.
3. Turn off the phone. Press and hold HOME and POWER button. The phone will start in recovery mode. You should see an exclaimation sign when it starts.
4. Press Alt + L, it will take you to the boot menu.
5. Press Alt + S, to start the update process. It will take a while so be patient.
6. When the update completes, it will prompt you to press HOME + BACK to reboot.
7. After you reboot, the update will complete and then automatically reboot.
Thats it! Be sure that you have the right firmware for your handset beforehand, so don’t come crying to us if you fluff it up!
