iPhone 3G with ERROR 1604 -- Will not restore...AT ALL.
I've tried EVERY SINGLE METHOD, and no solution to this ERROR 1604. I've tried on 4 different PC's (windows xp and vista). Several different versions of iTunes. Trying to restore a factory ipsw downloaded directly from apple... twice.
Get iphone in DFU mode, itunes see's it, shift click to restore 2.2 on iphone 3g (this is a factory ipsw). It starts, I get the apple logo with spinning wheel, and after several minutes itunes reports back error 1604 every time.
