Hello ipadforums! My problem has forced me to register here and get some expert help because, quite frankly, I am baffled. I am (as the thread title suggests) stuck in a DFU (or PWN) Loop after trying to upgrade my 3.3.2 firmware to 4.3.3 custom firmware. Before you ask, no, it is not a Recovery Loop. It's a blank screen. Tiny Umbrella isn't able to help me. To answer another question, yes, I tried restoring to a clean firmware then reinstalling custom firmware. No change. Yes, I have tried to manually exit DFU mode by holding the Power button and the Home button until the Apple showed. It never did. Finally, it is not an issue based around faulty hardware as my iPad was perfectly normal before attempting jailbreak. I am able to bring my iPad into a tethered state using Redsn0w but it's inconvenient. I want to able to access my iPad untethered and as far as I know no other firmware (aside from downgrading) supports this as of now. Can anyone help me?
