I rooted my friends Tmobile GS3 a few months ago and I need to unroot it. I have looked and searched everywhere for the unroot to 4.3 and i cant find it. I dont understand why it is so hard to find, im not a noob and i had the same problem with my sprint GS3 till someone posted the file for me. I would grately appreciate it if someone could post me a link to the file and a step by step, from the things I have been reading it seems like there is more to do than just flash the tar in Odin . So just to be safe if someone can add a step by step for me that would be great. And if necessary stock recover? Thanks guys Hope someone can help.
