iPhone 1st gen iTunes error 28

Hi!

I have an iPhone 2G/1st gen that I was going to transfer my apps to from the iPhone before I restored it (I copyed the applications from the applications folder). The iPhone was on the same OS as before (3.1.3). The iPhone was jailbroken before and after this happend. But anyway when I copyed all the apps I had almost no icons on the home screen left (I think the YouTube icon was there) so I decided to restore the phone. I turned it off and put it into recovery mode but when the progress bar showed up iTunes gave me error 28. What I have been trying to do: take out the battery, dfu mode restore, blackra1n, redsn0w, changing cables, changing comuters (XP and OS X 10.7 MBA), changing to diffrent versions of itunes, tried to restore to diffrent os

REALLY THANKFUL FOR ANSWERS!!!!!!!!!
