[Q] Cannot update my i747
I had my s3 rooted, and unlocked with stock ROM. And I think I've also freeze my "AT&T Software Update" a while ago, so it was stuck on 4.1.1. Now, I would like to update my firmware to 4.3 or newer, and stay stock. I tried to go to the setting and select Software update, but nothing happen. I've also tried to find that "AT&T Software Update" in Titanium Pro, but have no result. Can anyone point me to the right direction on how I can do it?
