Cannot jailbreak my phone with QuickPwn on a Mac

[zgall1]

I previously jailbroke my phone using QuickPwn on my Mac. When a new firmware version was released, I had to restore to factory settings to upgrade. I then tried to jailbreak my phone again. The entire process seemed to go smoothly until the phone restarted. It would go through the entire restart process but would not actually turn back on. I restored the phone and tried twice more to jailbreak (once after 2.2.1 came out) but I have not been successful. Does anybody have any ideas as to what the problem might be? Thanks.

Are you on 10.5.6? Did you run the script to re-enable DFU mode?

If not that could be your problem...

If that is the case, simply use a usb hub.
