[How To] G1 firmware update

[spyz88]

Does anyone know how will you be able to upgrade the firmware if you unlock and use it on AT&T since it is OTA?

[Poseidon79]

We'll figure that out after the unlock is out.. haha. I speculate you might have to put a valid tmobile sim in it to get the updates if they truely aare OTA... in which case the unlock process maybe have to then be update as well like the iphone.

Over the Air updates are controlled by the manufacturer/provider.

http://code.google.com/android/kb/security.html
The manufacturer of each device is responsible for distributing software upgrades for it, including security fixes. Many devices will update themselves automatically with software downloaded "over the air", while some devices require the user to upgrade them manually.

When Android-powered devices are publicly available, this FAQ will provide links how Open Handset Alliance members release updates.

But manual updates will be coming soon. As for myself I'm trying to get my own compilation of the Android OS on my G!

I just could not wait anymore, so I found a thread over xda-developers on how to download the official update, put on your micro sd card and update your phone.


1) Download the update from google website: https://android.clients.google.com/u...-RC19+RC28.zip

2) Rename the file you just downloaded to update.zip

3) Copy the file update.zip to the root of your micro sd card.

4) Now turn off your phone and turn it back on while holding the home key.

5) When you see a triangle with a exclamation sign and a phone, slide open your keyboard and press ALT-L to display the menu and then ALT-S to start the update process.

6) Wait for the update to finish. If prompted, press Home + Back to restart your phone.

7) Wait a little bit more and done!
