My friends son supposedly jailbroke this ipad and he has given it to me to try and fix, it turns on and shows the itunes connect picture and does charge even though it does not indicate it is charging. I want to just reset it and have tried to put in dfu and it still is not detected in itunes. I have tried 2 macs and 2 pcs so i know its not the system. I just don't know what to do to talk to it, windows does not even see it as being plugged in but like i said it does charge. any ideas would be great !!
