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.
i Phone X, i Phone 8, i Phone 8 Plus, i Phone 7, i Phone 7 Plus, i Phone 6s, i Phone 6s Plus, i Phone 6, i Phone 6 Plus, i Phone SE and i Phone 5s.

Once your i OS update is finished, go back to the hosts file and remove the “184.108.40.206 gs.apple.com” line again so that i Tunes can properly update as usual.
You may have no idea what the i OS firmware or IPSW file is, but with this powerful i OS downgrade/Upgrade tool, you do not even need to know them and the update and downgrade could be completed with only one click.You can now download i OS 11 full and final IPSW update for all compatible i Phone, i Pad and i Pod touch devices.We have the complete changelog of the update in one place too.For most users, the 3194 error is encountered because at some point in time, they used a jailbreak utility to modify their i OS device, and in that process of modification the jailbreak tweak modified the hosts file thereby blocking Apple’s servers.Initially that’s not a problem, but it can trigger the error when i OS is later attempted to be updated to a new version, restored from a backup, or modified.
