iTunes Givng Error 16
Hello, I have an iPhone 4 GSM 8GB model that I got from my friend and my Telus sim card (Also the carrier fir the phone) was not being recognised so, I automatically thought that I should do a factory restore, so I did but it just gives me error 16. I have tried EVERYTHING DFU mode, restore mode, PWNdfu mode, everything. And I still get error 16.
I have the latest iTunes, Windows 8.1 and I'm trying to restore to iOS 7.0.4
