I just noticed my iPad's USB port is faulty. I can charge it (with some adjust to the cable) but my computer just doesn't recognize it, appearing as Unknown Device. I've checked with Apple's website and tried everything I can do, including uninstall and reinstall iTunes and other softwares related to it, and also checked the Hardware ID of it, which is shown as USB/UNKNOWN.
Now I wished to get my iPad stuck in apple logo screen, which may prevent Apple from finding out I've jailbroken it, but I found that I can't do anything. The Erase Content and Settings doesn't do what it is supposed to do (with iOS 4.3.3, jailbroken with redsn0w). Now is there any other ways for me to hide the jailbroken status from Apple?
