I just updated my S4 to 4.3 the other day. Everything was working fine until i turned off my data (because i wasn't using it) once i tried turning it back on it wouldn't work. I've tried factory resets many times and just tried using it stock before installing anything. I've also tried battery pulls and taking my sim card out. Still no luck.
If anyone has a solution to this problem it would be greatly appreciated.
