My Galaxy S3 (i747) has just informed me that there is an OTA update available from AT&T. I have stock Android 4.1.1 on there right now, but I have the device rooted with Clockwork 5.x.
When I attempted to apply the OTA update, the phone (at first) looked like it was going to apply it, but then Clockwork opened with the error:
Failed to verify whole-file signature (along with some other messages) and when I rebooted, Android said something like "The update was interrupted."
So, here's my question, I guess: Is there something I can do with Clockwork 5.x where it can apply the OTA update for me -or- do I need to:
- Flash stock AT&T recovery (Will this remove root? Does that even matter?)
- Apply the update in the "official" way
- Re-download and re-apply Clockwork to re-root the device
If I follow either of these steps, all of my data will be preserved during the upgrade, correct?
