Hello MacRumors! I just recently purchased 2 iPhones for cheap. Reason why I bought them in this condition was because I used to be super into jailbreaking/unlocking iPhones when I had my iPhone 3g like 5 years ago and it was always super easy with no problems. Looks like times have changed.. iPhone 4 iOS 6.1 iPhone 4s iOS 5.1.1 The iPhone 4 is passcode locked and no matter how many times I try to select a custom IPSW ((I am certain it's the right one (10B144)) but it keeps saying "The iPhone could not be restored. An unknown error occurred. (3194)" Why am I getting this error? and is there any other way to restore a passcode locked iPhone 4 without updating? The iPhone 4s is jailbroken with redsn0w. I have been searching everywhere and only found one method that truly is free. https://www.youtube.com/watch?v=3pE8VuFjI0M Can someone please confirm that this (SAMprefs method) works? I gotta figure out how to get a hold of a T-mobile micro sim and don't want to go through that trouble for nothing. Any help would be greatly appreciated!
