How to prevent itunes from updating
You may need to flush your DNS cache for the change to take effect, though usually just quitting and relaunching i Tunes is sufficient to get the app to recognize the change.Once your i OS update is finished, go back to the hosts file and remove the “22.214.171.124 gs.apple.com” line again so that i Tunes can properly update as usual.
Or better yet, just let i Tunes or i OS update itself without trying to use the firmware files manually.
If you need them, you can get the latest versions of i Phone firmware, i Pad firmware, and i Pod touch firmware directly from Apple.
Keep in mind that the signing window for downgrading i OS versions has shrank dramatically, and without a history of storing SHSH blobs there is no way to revert back to prior versions of i OS once that happens.
In that case, no amount of tweaking hosts or adjusting IP’s is going to make a difference to restore to older IPSW, and thus you would have to either keep the current i OS version or opt to upgrade to a newer version to escape the 3194 error.
If you run into Error 3194 within i Tunes when you are trying to restore your i Phone, i Pad, or i Pod touch, you can fix it by temporarily blocking Apple’s firmware signing services.
Error 3194 seems to usually be triggered when unsigned or expired firmware is used, often during an i OS downgrade or upgrade, or even during some restores.

This applies to all versions of i Tunes on both Mac and Windows PC, here’s how to resole the error.
