The screen was frozen the other night and i tried to turn it off and it would not respond when i tried to move the red bar to turn it off. It died over night and then the next morning i plugged it in for a long time and when i got back to it and tried to turn it on nothing happened. It is not jailbroken or anything like that. I have tried to put it in DFU but it wont power on or anything. I have tried a different cord and nothing.
