So one day i turned on the bluetooth and accidentaly leaved it on for 7 hours. When i tried to turn it of the phone restarted with the bluetooth off. When i restart from button the bluetooth is on and the same process i have to repeat over and over, and no even if it says it' s on it wouldn' t work. So i read some forums and they said i need to REHOT the BT module. What does REHOT mean and how do i do it? and after the phone restarts with the BT off i cannot turn it on again.
