First off, it isn't my phone, it's my GF's S3. Now the problem is weird and I can't seem to find anything about it online. This is what happened (as far as I know). Phone is not rooted in anyway. Anyways, I was trying to update to JB for her and I kept getting the error 402-6 (Can't remember exactly) and I never could get it. Then one day we woke up and it looked like it updated by itself at night, which is nice but it caused something to happen and it's a seriously problem. I can no longer access the phone's settings at all. I've tried to do the softkey setting shortcut and it says touchwiz has stopped. The notification bar setting shortcut says the System UI has stopped. I've tried nova launcher and an explorer app with no luck. I did see a face unlock setting in the explorer app that goes into the settings, but when I tried to open it through the explorer it said it could not be open. It's almost as if her settings got wiped away completely. I've tried to reset/power off/battery pull the phone with no luck. Lastly I tried a factory reset (power/volume/home method) with no luck. If anyone knows anything, please help. We will be taking the phone to a store most likely Tuesday.
