Hello.

Yesterday, I browsed internet On my iPad with iCabmobile, when suddenly screen went black (with fast animation from left side of screen to right), and iPad rebooted. I booted it with redsn0w (iPad with 4.3.5 firmware with tethered jailbreak) and after a while it rebooted again. It's came to my knowledge that there is untethered jailbreak for 5.0.1, so I decided to backup all my data and update firmware, but when I connected my iPad to PC there was no reaction at all - not even "not charging" message on the iPad's status bar. It cam connect in DFU or rescovery mode, but it can only restore firmware - i can't make backup.

Will upgrading to 5.0.1 resolve this problem or is it harware problem? I still have one and a half weeks of warranty, so I need some help fast. If this will not help i'll go and return iPad for warranty.

Thanks in advance.
P.S: sorry for my bad english.
