Generally, T-Mobile provides OTA updates to the OS, but if you have unlocked G1 or not in US/UK, you can still perform firmware update. Here, we will update firmware from RC-19 to RC-29. The firmware version( or Build Number) can be seen at Settings > About phone > Build number
As required with any phone mods, make sure the battery is fully charged or atleast more than 50%.
IMPORTANT : This update is known to work only on US G1 (TC4), don’t try this on your UK G1 (TC5)
Steps ::
1. Download the update zip archive.
2. Rename the archive to update
3. Copy the file to the SD Card.
Note : Connect the phone to desktop and then transfer the file. Don’t take out the SD card and use the card reader.
4. Turn off the phone. Hold the HOME button while turning on the phone. The phone will start in bootloader mode. You should see an exclaimation sign when it starts.
5. Press Alt + L, it will take you to the boot menu,
6. Press Alt + S, to start the update process. It will take a while so be patient.
7. When the update completes, it will prompt you to press HOME + BACK to reboot.
8 . After you reboot, the update will finalize and automatically reboot.
Thats it !
