How to Fix iTunes Error 3194 while Updating/Restoring to iOS 5

Have you encountered iTunes error 3194 is while updating or restoring your iPhone, iPod Touch, or iPad to the latest firmware, iOS 5? Well, one reason this error occurs is that iTunes is unable to connect to Apple’s update server.


If you have previously jailbroken any iDevice, then your hosts file was definitely edited, even if it was not you who did it. Jailbreak tools such as TinyUmbrella also edit the hosts file by adding the following entry, that points to Cydia server.

This is done in case of downgrading an iOS firmware, an action which Apple does not otherwise allow. The hosts file entry is to trick iTunes into believing that it is talking to Apple’s servers, while in reality it is conversing with Cydia’s.

Coming back to the topic of this article, the same hosts file entry you have added while downgrading iOS firmware or while saving your device’s SHSH using TinyUmbrella, is responsible for the iTunes 3194 error.
