So, I tried rooting my S3 today, and it didn't go well. I restored it back to stock via Odin. But now, I have another problem. After upgrading all the way to 4.1.2 and restoring my backed up data, I can't install any apps. All the apps in the play store give me the message "App is not compatible with your device". It's horrible. I've spent almost 6 hours on this whole ordeal and i'm lost now. Please help.
