I have a custom recovery called, "teamwin recovery project 3.0,2-0" I've gone thru the settings and found a wipe menu, it doesnt work. I've factory reset, reset the cache,system,data, even format data. Didnt work.

Im totally out of options and i really dont want a bricked phone, beacuse i still have another year and a half in my contract... Please help
