error 3194 on iPhone 5

A friend of mine bought a used iPhone 5, it worked fine for some days but now it's stuck: if i turn it on, i get the "iTunes logo and cable" screen, and i can't do anything.

I tried to restore it via iTunes but i get error 3194. Tried the same in DFU mode, same result. I tried both with and without the hosts file entry. I disabled my antivirus. All of this was tried on two different Windows 10 computers with the latest version of iTunes. I also tried to use tinyumbrella, but all the versions of tinyumbrella that i could find did not have the "start TSS server" button, and this i cannot really understand.

My friend is not tech savy so i don't know exactly what he did to break it, i know he plugged it to the computer and did something. The phone could be jailbroken but i don't know for sure, i don't even know what version of iOS it's running.

Can this be fixed? I just want the phone to work, i don't care about a specific iOS version.

    It is possible you're using the wrong firmware file. You can only install iOS 9.2.1 on your device currently.

    I'll try to manually download that firmware and install it. The same error happens if i let iTunes download the firmware by itself though, so i'm not sure that's the problem.
    I'll try and report back
  • damn. i tried with the 9.2.1 firmware and it didn't work. then i tried to let itunes do it again and this time it worked. i don't know why, but i'm happy with it.
    thanks for the help!
  • Once you having the problem of iTunes error, you could try to install the latest version of iTunes and try to update or restore again. If this doesn’t help, it’s because of a simple problem with the hosts file, follow the steps below to fix.

    Step 1. Make sure that iTunes is stopped on your computer (Widows/Mac).

    Step 2. Open host files on your computer:

    a. For Windows users: c:\windows\system32\drivers\etc\hosts

    b. For Mac users: /ect/hosts

    Step 3. Open hosts file with administrator rights.

    Step 4. Copy "" into the last line of the "Host" file.Then, "Save" the file.

    Step 5. Connect iPhone to PC via USB cable and open iTunes.

    Step 6. Press on "Power" button for 10 seconds to turn off your iPhone.

    Step 7. Put the iPhone/iPad/iPod into DFU mode by turning the phone off and then holding down the Home and Power button for 10 seconds, then release the Power button but hold onto the Home button until iTunes tells you that the device is now in recovery mode.

    Step 8. In recovery mode, you can restore iPhone. Hoever, restore iPhone will erase all data on your iPhone, so make sure you've ever backed up iPhone with iTunes or iCloud.

    Step 9. Once your iOS update is finished, go back to the hosts file and remove the "" line again so that iTunes can properly update as usual. This is an essential step otherwise you may encounter future errors when trying to update or install iOS versions.
