5s updated to 8.3 but got blue screen
Got support from apple on how to reset and restore from back up
Followed instructions and was working for one day. When I connected to another computer with iTunes and trusted it again crashed.
Rest few times and restore from last back up.
Suddenly it showed a crash dump screen with dump message saying there is no drive found for this platform.
