I see you have a wm8650 based on what you put in your profile. I am unfamiliar with that tablet, but others will probably be able to help you recover the device. I just wanted to post the device you had to help others help you faster. Did any settings get changed or new apps installed before the OS froze or did you try to apply an update that failed?
