How to 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 unsignedfirmware, 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.


“The iPhone “iPhone” could not be restored. An unknown error occurred (3194).”

    I tried both ways did not work on my iphone 3gs however my phone is unlocked/jailbroken. does this affect it somehow?? Is there anyway to fix my unlocked phone that I can do myself?, this happened before and I had to pay 40 bucks to someone I didn’t even know to do what you guys say I can do myself. I felt it was total rip off so I could really use your help. My phone is a iphone 3g and it is unlocked via cydia.
    thanks

    I tried all the above, and still could not get past the 3194 error. What I did in the end was renamed the c:windowssystem32driversetchosts file to hostsold, and tried restoring again, and hey presto it worked ! Now running IOS 5 on my 3GS. Non JB this time !
