Can I unroot my AT&T GS3?

[Blaze132]

I was just curious to know if I could. And would it void my warranty if i were to unroot it?

Yes you can unroot. If you were to unroot and return to stock rom before sending it in for service or anything, your warranty would not be void. Somebody can correct me if I'm wrong, but I don't believe there is a SBF available yet, so hopefully you made a backup before you flashed a rom! It shouldn't be too long before one gets released though, so if you don't have a backup, just stay cool

Like it was stated before you can unroot and its really easy, you should be able to go back to completely stock without loosing your data, even if you changed roms, just as long as you made a backup before making anychanges, same goes for your recovery you just flash the stock one, through ODIN, everything is done through odin, also make sure your reset you flash counter if you did change roms
