I'm trying to restore my iphone 4, without upgrading to iOS 6. I updated iTunes and downloaded the correct IPSW file, but when i try i get the error: "This device isnt eligible for the requested build" I checked my hosts file, but it doesn't have any line resembling 22.214.171.124 gs.apple.com, so nothing to comment. The phone is NOT jailbroken What can I do? why is that happening? Thanks for helping!
