I jailbroke before, but I'm having trouble upgrading

My iPhone is already jailbroken on 2.2. I'm trying to go to 2.2.1 iPhone software and have downloaded pwnage 2.2.5 and created my custome restore .ipsw file on my desktop. I connect my iPhone to my computer and put the phone in recovery mode. I hold the option key when I click the restore button in iTunes and then select the .ipsw file I created in pwnage (using simple mode). I keep getting the error message that the iPhone could not be restored and an unknown error occurred (1600). Any idea what gives?

Put it in DFU mode, then give it a shot 😉
 
Isn't that what I was doing? Doesn't DFU put it into restore mode? I got to that point, it just won't restore when I select the package.
 
Well, I'm trying to enter DFU mode in pwnage and I keep on failing. I follow the instructions and it keeps on stopping and the point where I'm holding in the home and power buttons. Pwnage always gives me the error message right around the 5 second point of holding in home and power.

Hmm... Are you running OSX 10.5.6?
 
Nope. 10.5.5

I'm going to try to use a powered USB hub instead of directly connecting to my MacBook to see if that helps.
