Fix Error 3194 When Restoring Firmware

Occurs when trying to install an old firmware and Apple’s server disallows the installation. The only solution is to have SHSH backup and modify the hosts file to point to Saurik’s Cydia Server where they are backed up (or localhost if you have it yourself).

You can fix iTunes error 3194 by adding Cydia’s SHSH Caching Server to the hosts file. You can do this either by using TinyUmbrella or you can also manually edit the hosts file. We’re going to explain both methods.
