Possible causes of iTunes errors 3194 and 17 on the iPhone 7

As the alert message implies, the iTunes error 3194 and error 17 is telling you that something is making your iPhone not eligible for the requested build in iTunes. That something seems to interfere with the connection between your iPhone and iTunes or the Apple server. Such an interference results to the iTunes software not being able to establish connection thus could not communicate with your iPhone or with the Apple server.

The good thing about these iTunes errors is the fact that they are not associated with any hardware issues. This denotes that you have a higher chance of getting rid of them and resolve the underlying cause without having to take your device to a technician for hardware repair. But what could have gone wrong in the software layer of iTunes or your iPhone that’s preventing you from completing the restore or update process?

Listed among the possible triggers of iTunes error 3194 and error 17 are security software like antivirus and firewall, corrupted files, and network connectivity problems. Here’s how each of the said factors can cause problems when updating or restoring your iPhone 7 in iTunes and end up with these two error codes.

  • Security software – antivirus, firewall, and relevant tools are primarily designed to block or prevent any threat to the computer’s security. Among the list of common source of threats are external devices. Now, here’s the catch. The moment you connect your iPhone 7 to the computer with the USB cable or connector, your iPhone will be recognized by the computer as an external device, like storage media. The security software’s main task is to prevent any security threat from accessing the computer system. So if that is enabled on the computer and perceives some risks on your iPhone, automatically it will act as intended and deny access or disconnect your iOS device. In this way, possible transmission of bugs from the suspected external media is halted. Firewalls, antivirus, and other security suites are designed to act the same as prevent measures.
  • Corrupted files – when a program gets corrupted, it won’t be able to function as intended. For example, when a file, application or computer program may have failed to load or work normally because it gets corrupted. What usually happens is that something went wrong in the program and that triggers it to become erratic. In this case, it is possible that a certain program in the computer is affecting other programs’ normal function, particularly with iTunes. The damaged file is most likely within the iTunes library or other relevant components. Thus, even if iTunes is working properly the error still shows because the corrupted file is triggering it the moment you run the iTunes program.
  • Network problem – another possible factor that can interrupt the iTunes normal functions is a network connectivity problem. Normally, iTunes will need to access the Apple servers to carry out input commands from users. For example, for download requests, iTunes will access the Apple server to access and get requested contents for download. The same thing it does when you try to update your software. iTunes will communicate with the server for the latter to grant access to the requested update, thus allowing you to download and install the specific update file on your iOS device. However, if something goes wrong with the network and the connection suddenly fails, communication between iTunes and the Apple server will be lost. As a result, on-going process will be halted and relevant errors are likely to show up. In this case, the problem could either be on the Apple server or your network service provider. Usually, everything should go back to normal with iTunes services once the network problem has been resolved.

Knowing all the possible factors that can trigger iTunes to prompt errors 3194 and 17 when attempting to update or download iOS on your iPhone 7, the next thing to work on is the resolution.

How to deal with iTunes error 3194 and error 17 on your iPhone 7?

It is recommended to start working on the possible causes because doing so will increase your chance of getting quick solutions. So here are your first options.

  • Manage security software/settings on your computer. If you are using a security  software on your computer like antivirus or firewall, try to disable it temporarily and connect your iPhone 7 again. Otherwise, you can just configure the software to lower or remove restrictions to your iPhone so as to allow full access to iTunes services. The latter option however is only applicable if you are familiar with the security software interface in use. If not, consider the first option.
  • Check network connections. Again network problems can be the main reason as to why iTunes couldn’t communicate with the Apple server and couldn’t complete your request. That being said, check and make sure your network connection is stable. If necessary, try to reboot your router to eliminate glitches and establish fresh connection from the network towers/servers. As much as possible, try to resolve any network issues first so you can use iTunes without any more troubles. Also make sure that there are no on-going outages that might have affected network services in your location.
  • Update iTunes, if necessary. If you suspect that the root cause is within iTunes, you can either try to isolate the problem or uninstall iTunes and its components.

Retry loading iTunes after the reboot on both devices and see if everything goes well this time.

Third Solution: Bypass connection to the router.

Bypassing means connecting the computer directly to the router using an Ethernet cable. This will help especially if the problem has something to do with network connectivity. So if you have the Ethernet ready, follow these steps:

 

  • Turn off your computer and modem/router.
  • Connect the Ethernet cable to the right port on the computer and the other end to the modem/router.
  • Turn on your modem and then your computer afterwards.
  • Connect to the Internet. If it works, then try to use iTunes again to update or restore your iPhone.

 

Fourth Solution: Reset hosts file.

Hosts files are operating system files or plain text files in the computer that map hostnames to IP addresses. They contain lines of text consisting of IP addresses. Just other types of resets, hosts file reset can help eliminate any glitches or corrupt domains from that might have caused conflict to the iTunes and relevant components.  Should you wish to give it a try, here’s how to reset hosts file on a Mac computer.

 

  • Launch the Finder tool.
  • Navigate to Applications-> Utilities.
  • Open Terminal.
  • Type this command sudo nano /private/etc/hosts and press Return.

 

    • Enter the password you used to sign into your computer and press Return. The hosts file will be shown in the Terminal. Be sure to use a non-blank administrator password or no password admin account. If necessary, add a password to your admin account in the Users & Groups preferences section. Also note that Terminal does not show your password as you type it so make sure you type in the correct password. Terminal will ask you to enter the password again after entering the wrong one.

 

  • Use the arrow keys to navigate the screen and look for an entry that contains “gs.apple.com“. If you don’t see any entry that contains the said label, it denotes that hosts file is not causing the problem. Close the Terminal and proceed to the next applicable solution.
  • Add or insert the # symbol and a space (# ) to the beginning of the gs.apple.com entry.
  • Press the Control-O to save the file.
  • When prompted to enter the filename, press Return.
