So I have been trying to fix my iphone 5 for the past 4 hrs I'm trying to restore and start fresh on 6.1.2 every time I try to restore I get the 3194 error I fix that with the host file fix and I get the 1600 error I'm so lost all I want to do is restore my iphone and start fresh that's all please help. Just to show that error does some time stem from an iOS jail break here's a lovely quote from imore.com EDIT *** "According to iTunes diagnostics, this error arises when you try using unsigned firmware especially during a downgrade or even iPhone restore. When you upload a custom jail broken firmware on your Apple device, this error is bound to be triggered as it is not recognized by Apple firmware signing services on iTunes. The resultant effect is blocking of your firmware and in essence you cannot change it on your device. Jail breaking is a common trend among most Apple device users but when you seek to change it to custom iOS firmware, the error crops up. This problem is very common if you have used CYDIA to JAILBREAK." Oh but wait you guys letting me know to use GOOGLE should have known that. I mean being GOOGLE users and all.
