The Cupertino-based tech company doesn’t like its customers to jailbreak iPhone 4S / 4 / 5 / 5S / 5c, but iOS 7.1 jailbreak is now not possible.

Hosts file on your computer is where the problem lies. iTunes is using this file to connect to the activation server used by Apple. This file is kept on Windows and OS X computers. iPhone users who have changed their hosts file get error 3194 while they update to iOS 7.1 using iTunes.
