I was attempting to go straight from 2.2.1 firmware into a 3.0 firmware jailbreak without going from 2.2.1 to 3.0 to 3.0 JB. I used redsn0w 0.72 and placed my iPod into DFU mode and then followed the sticky for windows JB and it got stuck on the Green Arrow pointing at the hard drive for ten minutes, so I unplugged, and tried to get it into DFU so I could retry. I haven't been able to get into DFU mode and I am getting the connect to iTunes screen. iTunes isn't even showing my device as being connected and my iPod powers down instantly from CTI screen randomly it seems. I've tried many different methods for DFU and can't get anything to work, I can't get it into restore mode either. Any ideas?
