Hi all. I want to update my AT&T Galaxy S3. United states version. Right now its on 4.1.1 but I want to switch to... 4.2.2? I think that is the latest version. However, I also want to root. Is there a pre packaged Odin somewhere that will root, and update to the latest version of android? I don't think I want to get into all those custom ROMs right now. I'll do that later after I'm more familiar with the factory one.
