I am trying to update a jailbroken iPhone 4 IOS 4.3 to IOS 5.0. I have acquired the needed things from this link http://www.jailbreaknation.com/jailbreak-ios-5-5.0-on-iphone-4-ipod-touch-ipad-with-redsn0w. First, I got the error 3194 when when itunes was trying to verify the .ipsw file with apple. I fixed the problem by downloading TinyUmbrella and turning on the TSS server. But now I get a 1604 error when itunes trys to prepare the iPhone for restore. I sort of fixed that buy putting the iPhone into Pwned DFU mode using IREB or Redsnow 0.9.9b8. Now I'm getting error 1600. How do I fix this?
Extra Info: Itunes version: 10.2 Yes I have tried normal DFU mode and Recovery Mode.
Thanks In Advance.
