Hi everyone. I am writing this post on behalf of my wife who owns a Galaxy Tab 2 10.1. When she turns the unit off, it automatically reboots back on again and this problem just started occurring right after a major update (I assume the update was to 4.2 jelly bean from 4.1). I have searched the internet for issues like this from other users and what I'm reading is that the machine should be reset to factory defaults. Is there any way that I can downgrade back down to JB 4.1? Thank you for any responses in advance as I am fairly new at tablets.
