The official Ice Cream Sandwich Android 4.0 update was released over the air (OTA) for the HTC Amaze by T-Mobile recently, but some people who tried to update their phones were greeted with a red warning triangle indicating a failed update, specially those who had manually flashed previous leaked Android 4.0 updates on their device.

That’s when miked0602 of the Android-Dev community took it upon himself to find out how exactly one could flash the update without failure. And after many trials, he has finally come up with a full step-by-step procedure to help people update to the official ICS Android 4.0 OTA release, version 259660. The procedure involves returning to a proper unmodified stock ROM so that the update doesn’t fail and completes successfully.

If you’re one of those who have played around with leaked Android 4.0 updates on your Amaze 4G and would like to update to the official Ice Cream Sandwich Android 4.0 release, follow the detailed steps on the official Android-Dev page. If all goes well, you should be running the official Android 4.0 firmware on your HTC Amaze 4G. Let us know how it works for you, in the comments below.
