    My issue is rather different.. the WIFI and BT can be switched on when the bezel is removed but signal is weak(understandable because antenna is there).. but when i connect the bezel, the WIFI and BT stops working(cannot be turned on) i’ve tried switching to another bezel and can’t work either.. seems weird to me that antenna could be causing this

  • Wow this worked! Eventho they are not exactly the same model type, they are very identical since I currently own the AT&T LTE Version ( Galaxy Note 2 i317) I had to heat up that piece and it worked!
