Got iPhone 4 which is on iOS 5 and want to restore it to iOS 5, so i downloaded the iOS 5 and tried to restore but iTunes give me and unknown error 3194 What shall i do?
Try this, and if it does not work try iFaith and if that does not work you are stuck on 5.0.1 http://cydiahelp.com/downgrading-from-ios-5.0.1-on-iphoneipad-and-ipod-touch-step-by-step-guide/
Actually, iFaith 1.4 was released today, which will allow you to restore to any firmware you are currently on or have blobs for, as long as it's not an iPad 2 or iPhone 4S.
iOS 5 is not signing any more. You have to restore it to iOS 5.0.1 ---------- oo i remember, you need to preserve your baseband as well if you care about unlock otherwise you will be crying like the people here http://forums.macrumors.com/showthread.php?t=1270258
