I recently got a k850 secondhand. It starts up with the SE logo then goes into a continuous loop of restarts where the keypad and camera lens ring lights up and will continue to do so until the battery is pulled. I have tried to do an SEUS update and the phone is apparently up to date with the latest. Also I've tried to see if the erom can be repaired by the wotan client but it doesnt support the DB something something. Please any informative suggestions here?? thanks
