Fix iTunes Error 3194 While Restoring or Updating iOS on iPhone/iPad

Of all the errors that pop up every time I try to update, restore or (at times) even sync the iPhone, the notorious iTunes error 3194 is the one I fear most. Not that the error hasn’t got a fix, but the fact that there are plenty of fixes for the error and that you’ll have to try each one in a variety of combinations to fix the thing.

Apple’s support page for specific errors on iTunes isn’t all that helpful. For starters, Apple isn’t all that interested in people downgrading their iOS firmware. So naturally, all the signing is already done with so if you’re trying to downgrade to iOS 6.1.3 or lesser after an upgrade to iOS 7, you’re going to have a bad time. And when you’re dealing with a jailbroken iPhone, it’s going to be even worse.


Error 3194

If you’re real lucky – and I mean seriously lucky – you’ll not see any errors crop up when you try to update or restore. Most users who don’t usually tinker with their iPhones are these lucky ones. For the rest of us, here’s what you can do to fix the iTunes error 3194. (Check out this tutorial in case you are facing iTunes error 17 issue.)

How to Fix iTunes Error 3194 During iOS Update on Your iPhone, iPad or iPod Touch:

You’re just trying to update / upgrade the firmware but iTunes keeps throwing up this error. In most cases, it’s because of a simple problem with the hosts file. Here’s how to fix it:

  • For Windows, navigate to C:/Windows/System32/drivers/etc/ and find the file that’s named “hosts”
  • For Mac, the file is in /etc/
  • Open the file in Notepad (or any other text editing software) (for Windows users, open this with Administrator Privileges)
  • You’ll mostly have this line at the bottom of the file:
  • Error 3194 Hosts File
  • Either comment this line out by typing a single ‘#’ (without the quotes) in front of the line (before 74) or remove the line entirely.
  • Now, save the hosts file and then try updating your iPhone through iTunes.
  • In most cases, the error shouldn’t pop up now.

Again, if you’re lucky, this should work. To me, this method never worked but then, I had my iPhone jailbroken too many times. So that’s when TinyUmbrella comes to the rescue.

Fixing iTunes Error 3194 for a Jailbroken iPhone using TinyUmbrella

TinyUmbrella is a cool little software that you probably have heard of already.

Note #1: TinyUmbrella and this method are actually part of the 3194 error fix for “downgrading” your iOS firmware. But in some cases (like ours), it worked for an update too. It’s mostly because we had a jailbroken iPhone that wasn’t restored to factory settings. Here’s how it works:

Note #2: If you wish to downgrade, you’ll need to save SHSH blobs either to your local drive or on Cydia. Right now, Cydia has saved SHSH blobs up to iOS 7.0.4; you’ll need to save the SHSH blobs of your device (and you can use TinyUmbrella for this).

  • Download the iOS firmware that you wish to upgrade/downgrade your iPhone to.
  • Download TinyUmbrella
  • Connect your iPhone and close iTunes if it pops open automatically.
  • Open TinyUmbrella and then click on ‘Start TSS Server’
  • Put your iPhone in DFU (Here is  a quick guide to do this)
  • Now, if you are updating your firmware, you’ll have to click on Shift+Restore (Win) / Option+Restore (Mac) and point it to the iOS ipsw file you downloaded in step 1.
  • Hopefully, iTunes will restore it to the correct iOS firmware you pointed to and update your iPhone to it.

    I got error 1604 after doing shift+restore. I have a ipod touch 4g 4.3.3, jailbreak & has a cydia. Im trying to unjailbreak it or just restore. Any help? I got error 1604 and error 3194.

    Thanks bro. First method for updating iOS worked!

  • Aiyush

    I tried both methods. I have a jailbroken Ipad 2 Wifi with 5.1.1. I wish to update it to 6.1.1 using my ipsw file. If I use itunes, I get the 3194 error with or without commenting the address to the apple server. Using the latest version of TinyUmbrella, I started the TSS server. I then open itunes and shift+click on the update. Now I get error 11.

        • Justin Evans

          Same issue here, any solutions yet??

          • iGeeksBlog

            if you get itunes error 11, it mostly means there’s something going awry
            with the SHSH blobs. unfortunately, at this moment, there’s a lot of
            issue with firmware upgrades/downgr
            ades in ios 6. we’ll keep u posted when there’s a workaround.

        • Carminbook

          Same error here :-(

  • disqus_ryAw4ByLgl

    Will this enable me to update my newly bought ipod touch 4, with firmware 4.3.5 to 5.1.1? Or do I need shsh blobs…

  • haroon

    I did my iphone jailbreak. it was working 5 days. after 5 days I remove some software from cydia but my mobile going to restart every 4 secand? please tell me the solution this?

    • iGeeksBlog

      I guess you removed something important along the way. Looks like you’re in a bit of a fix. Here’s what I’d recommend: 1) first try rejailbreaking your iDevice. 2) if that doesn’t work, go ahead and restore your firmware through iTunes. You’ll lose the data if you haven’t backed up in a while. Unfortunately, that seems to be the only way out if the restart loop keeps happening even if you connect your iPhone to the computer.

  • decu

    Nice 1. Perhaps you can tell us how to regain the wi-fi? As the one on mine seems not to work. Thanks anyway as the 1st method worked.

  • Patrick

    I discovered another issue related to my previous comment, and that is; Apple does not allow you to edit your app email address on any app from Apple Manager. This happened to me when I forgot my security questions, they did not allow me to download my apps, and all my purchased apps are gone. These people are materialistic, and do not care about customer support. I advice everyone to sell his iPhone like me, and by any android machine he or she likes. Believe me you are going to have a big headache and waste hundreds of hours on Apple stupid machines.

  • Patrick

    Whether jailbroken, dfu mode, recover mode, nothing work, and iTunes 11, and 11.2 is a smart software that can recognize any mode. The server for 6.1.2, and up is closed, and Umbrella cannot find any server only SHSH blobs that are not useful in new iPhone 5 firmware, or any updated iPhone to new firmware. Apple tricked people in version 6.1 claiming that there is a battery leek and that is a dump trick, because batteries cannot be fixed in software, only by changing them. Nothing can be done, until people working in Apple leek us some tricks to downgrade our iPhones, and error 3194 is an upgrade issue not a host line. Don’t play with host file or try on another machine, nothing works. Moreover, iTunes cannot read Firmware 6.1 and up correctly, and I discovered this on Jailbroken, and non Jailbroken devices. It leaves many free apps behind without uploading to your iDevice. You need iFunbox to upload the other free apps, or purchased ones with your Apple ID.
