1.1.3 upgrade went wrong need help downgradeing

[MoBurkhardt]

Hi there

I have one of the early iPhones that I use in Sweden(Europe) so I need it unlocked and jailbroken. For a long time I was running 1.1.1 on it and was happy not upgrading to 1.1.2 because there wasn't much new stuff in that release.

Now I tried upgrading from my unlocked, jailbroken 1.1.1 iPhone to 1.1.3 via Nate's image file. But at the first restart it kept refreshing springboard and i could not use it.

So I tried to restore it to 1.1.1 using alt-iTunes method and a good image. That left me with a black screen as I recall and I made something stupid and pressed the restore button in iTunes with out the alt so it restored/upgraded me to 1.1.3 "as it was meant to be".

Now I am stuck with that stupid itunes + cable picture on the iphone and when I try to Restore again using alt+iTunes I get the following message:
"The iPhone "iPhone" could not be restored. An unknown error occurred(1)"

I have two systems one Inter/win(MacBook) but iTunes doesnt work on windows. And one PowerMac G4 (very old) with iTunes 7.4 and xcode,iPhuc,...
Everywhere I get the same "Unknown error occured(1)"

Please Help.....
