[Q] Updating rooted AT&T Galaxy S III to stock 4.1.2?
So here's the scenario. I've gotten a replacement phone from AT&T and it came with 4.1.2 installed, but now it has 4.1.1 because of a botched Nandroid restore (incoming texts began to disappear, then the ENTIRE TEXT THREAD did. And never reappeared.). So I unrooted and hard wiped, unfortunately to 4.1.1.
Now I'm trying to figure this out: How can I root the replacement, perform a Nandroid restore (from old phone to replacement) so that everything is intact, and then upgrade the phone from 4.1.1 to 4.1.2 after it's been rooted? Obviously the OTA update won't work at that point, and despite searching this board and countless others for hours, I can't find anything that says how to do this in terms that I can understand, as all I've ever done is root stock. I downloaded loserskater's rooted stock 4.1.2 ROM but I certainly don't know what to do with it.
