How to Fix iTunes Error 3194 When Updating iPhone to iOS 7 on September 18

Hello there! If you are new here, you might want to subscribe to the RSS feed for updates on this topic!

It’s finally here! If you encounter iTunes error 3194 when updating iOS 7, let me show you how to fix it.

You’re probably trying to update your iPhone to the latest iOS 7 using iTunes but kept getting this error. If you’re new to using iPhone, one of the most important things you need to know is you can never downgrade your iOS. This is by designed, and of course, how Apple wants it to be.

One of the main reasons is that Apple doesn’t want you to jailbreak your iPhone. For example, iOS 6 has exploits that can jailbreak iPhone 3GS, 4 and 5. Since Apple can no longer patch or fix previous iOS which version which has been released to public, they can only fix those issues in the next release.

iOS 7 is a total overhaul of the iOS 6 mainly the user interface. It’s also designed for the latest iPhone 5s and 5c which are coming to you really soon.

Now let’s go back to your iTunes restore error 3194. This is a very common error if you’re trying to restore your iPhone. Error 3194 is a response from iTunes telling you that your iPhone is not eligible to be restored to a particular iOS version. Apple will only allow you install the latest iOS, but why are you still getting this error if the iOS version you’re trying to restore to is already the latest? Well, the problem lies with your computer’s hosts file.

iTunes uses your computer’s hosts file to “communicate” with Apple’s activation server. It exists in both Mac and PC. If your hosts file is modified, you will definitely get this error message when updating to iOS 6.1.4 using iTunes.

So, how did your hosts file got modified in the first place? Jailbreaking software such as TinyUmbrella and redsn0w are the culprits. If you’ve used one of these programs before, they will modify your hosts file to trick iTunes to NOT connect to Apple’s iOS restore verification server. Why you may ask? On older devices, it IS possible to restore to an older iOS for as long as you have the SHSH saved. This is a separate topic but is related so let’s discuss about this another day while we work on fixing this issue.
