early iphone in a 1604 nightmare

[davidsays]

Hey guys,
I am in a spot of bother. I have an early iphone(number 94or95)
It was freed with iphonesimfree when it came available last august.
It worked perfectly till last week when I put it into airplane mode and it froze.
Since then I have tried allsorts to get it reset but I keep getting the error 1604
I tried on 3 different macs and a pc using all the different solutions suggested on the
Varius forums. I tried different user acconts, restarting, different machines, forcing to restore from the file itself with itunes closed, , running repeatedly (+15 times), and nothing at all has worked to restore the unit
I am not sure which firmware the phone has its either the first or second in the series .
But I cant reboot directly either using the option/restore keystroke
Is there anybody who knows how to zap these machines back to the factory setting?
Please help.
I am using itunes 7.6.1(9) on a g5 mac
