First off i don't know anything about this ipad has it was give to my wife at work because friend said it didn't work. (dead)..
Well if i connect it to ac it will lite up and show apple logo for about 5-10 seconds and screen goes black and 5-10 seconds turn back on to apple logo again . it will due it for has long as you have it plug in to ac hours.
It will NOT CONNECT TO COMPUTER AT ALL WHEN YOU PLUG USB TO IT.
I just try redsnow and it just stop at rebooting on screen on pc not ipad.
and ideas what to do. i have try connected to pc to put it into dfu mode but no luck. i have even got mad and had it pluged into pc and just held home button down on it for 20-30 minutes and nothing.
