Never dropped it, thrown it, anything, no where near water, etc, I've treat it perfectly fine. It's a rooted Nexus S 4g with TWRP mod not Clockwork or anything.
I recently turned it off and turned it back on. when I turned it back on it gets stuck at the google screen with an unlocked lock with shows that it's a rooted nexus.. I really need help... PLEASE help me!
