How do you unroot the GS3 and get back to stock unrooted? I am currently just stock rooted. I'm just done with flashing and don't want to worry about something happening to my phone while I'm rooted, and am sick of it not being able to take the VZW update on a daily basis. I understand there is an unroot in the superuser app, is it as simple as clicking that and it will unroot by itself? Is there more I need to do? Thanks for your help!
