    Im trying to restore an iPhone 4 to 4.3.5...

    Im sing the latest version of umbrella to get the restore started.. but once it gets to the preparing iPhone for restore stage, it hands for a bit, then gives me the unable to restore 1604 error.

    I feel like I've tried everything. Any advice?

    I was getting an error almost every time I tried to restore my 4 to iOS 4.3.3. I was pointing my hosts to Saurik, using TinyUmbrella, redsn0w, but nothing was working.

    I finally downloaded a fresh copy of 4.3.3 from iClarified and used PwnageTool. Finally did the trick.

    No idea why I didn't think to try PwnageTool. For some reason it was able to got the job done. Thanks for the tip
