Fix Error 3194 When Restoring Stock or Custom Firmware

Users often reports error 3194 when restoring either stock, or custom firmware / iOS. These are the steps to fix error 3194 when restoring custom / stock firmware on iPhone / iPad / iPad.

iTunes error 3194 usually appears when you’re trying to restore an unsigned firmware, often during an iOS downgrade or even during some restores. If you run into Error 3194 from iTunes, you can temporarily fix 3194 error by pointing iTunes to Cydia’s SHSH server where you’ve SHSH blobs saved for that particular firmwares.

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).

*** If you’re getting iTunes error 3194 with the latest firmware (Signed iOS) then simply remove the Cydia’s SHSH server IP, if it’s already in the Hosts file. It’s the reverse of the process explained below.
