I was experiencing problems with my rooted mj5 so i used that popular thread on how to revert to stock mj5. Everything went smooth, but im still having the bootloop problems. The custom lock logo is gone on bootup so i know its true stock mj5 now, but my loader hangs on the ATT animation logo for a bit then keeps restarting. This process goes on and off for a few times until it manages to pull itself through. Should i call ATT for a replacement or is this fixable?
