hang-the-9 :
Need some more info. When you say "rebooting" are you talking about just turning it off and on or doing a factory reset? Need details about what "frozen" is, you turn it on and what happens?
Of course during factory resetting I never heard it can freeze just by turning it on and off anyway I guess I will need to take it to some place to get fix,
here nobody knows how to make it work
