For those who do not have the Hosts file. Think a little. Sometimes, at least. Notepad automatically searches for.txt files, and hosts, if you have not touched anything before, “lies” as a regular file that is not displayed if you search for.txt. At the bottom right, when searching, change c.txt to All and everything will “lie”.

Error 3194 when restoring iPhone or updating iOS. What to do?

Error 3194 often occurs because iTunes cannot connect to the update server. This error may appear when trying to update iOS, as well as when restoring an iPhone or iPad.

When restoring an iPhone or iPad, iTunes must download the firmware file (IPSW) from Apple’s server. The second step sends an iTunes request to the Apple update server to sign the firmware file (IPSW) with an ECID certificate. Well, then, if no problems arose, the recovery process starts. However, if at the stage of sending the firmware for signing to the Apple server, no response comes from it, then error 3194 occurs.

Error 3194 can be caused by software errors (the update process does not start or an error is generated at the very beginning of the update). If the error appears already at the final stage (more than half of the process status bar is filled in), then the problem is most likely a hardware problem, and you should not try to fix it yourself. Better to contact the service center.

If software errors are to blame (Apple stopped signing old firmware, the host system file was modified to use Cydia’s caching servers), then you can try to fix error 3194 yourself.

If your device does not have the most recent version of iTunes, you should update it using the Apple official website. Then you can try updating or restoring your iPhone or iPad again. The likelihood that everything will work out is not very high, but it’s worth a try.

If even after updating iTunes to the latest version, you cannot download the update or restore your mobile device, you need to proceed to the next steps.

First, you need to restore the contents of the default host file. If your computer is running Windows, then it is better to refer to the remediation algorithm recommended by Microsoft.

To fix the host file on Mac OS, you need to do the following:

  • Open the Terminal program.
  • Enter the command sudo nano / private / etc / hosts.
  • Enter the password (not necessarily empty) that is used to log in to the computer. When you enter it in the Terminal program, the password will not be displayed.
  • The “Terminal” program will display the hosts file.
  • At the beginning of the entry, add the # symbol and a space (#).
  • Save file (Control-O). After prompting for a name, press Control-X. Next. close the program.
  • After all these steps, you must restart your computer.

Then you can try again to update iOS or restore your mobile devices.

If fixing the host file did not help, then you can try disabling the security software for the time of updating or restoring. it can also cause error 3194.

Also, the problem may lie in filtering TCP / IP addresses in the router settings. Therefore, during the update, it is worth disconnecting the modem or router, and connecting to the network directly via a wired connection.

Software and hardware reasons

Software crashes can be solved even by novice iPhone users. The most common problems are:

  • the version of iTunes on your computer is outdated and needs updating;
  • the hosts system file redirects the requests of the official program, replacing the address;
  • the security system (antivirus) crashed in the PC.

If the message “Failed to restore iPhone. Error 3194 “, the source of the failure is hidden in the actions of the PC user himself. For example, if he tried to change the operating system of the phone to an older version. Old iOS firmware does not always work well with new, modern devices.

If iTunes does not “see” the smartphone, then the reason is hardware failures. These include technical damage to the modem and power outages.

Checking the hosts file

The question arises: how are entries containing “” added to the hosts file without user intervention??

If you have run the TinyUmbrella utility at least once, which allows you to download digital signatures (SHSH hash) of the iPhone and iPad for the current iOS from the Apple server, the program makes changes to the hosts automatically, without your knowledge. All subsequent requests from iTunes after the modification of the file are not sent to the Apple update server, and therefore no responses are sent.

First of all, check the contents of the hosts file if it contains a line or lines of the form: “” before this line (s) add the ignore symbol “#”, or completely remove it / them. For this:

On Windows, follow the Microsoft support guidelines:

    Start “Computer” and follow the path:

  • Find the hosts file (has no extension) and open it with the simplest text editor “Notepad”, or any other.
  • Find the line “” and insert a “#” (hash) in front of it, or delete it completely. If there are several such lines, you need to delete all of them, or insert a “sharp” before each.
  • In order for the changes to take effect, it is recommended to restart the computer.
  • Mac computers running OS X (Apple solution):

    • In the Finder, choose Applications. Utilities “.
    • Start “Terminal”.
    • Enter the command:
  • Enter the password used to log into your computer, then press Enter. When entering a password in the “Terminal”, the text will not be displayed. Be sure to use a non-empty admin password.
  • The “Terminal” will display the contents of the hosts file. Use the arrow keys to navigate to the entry containing the address “”.
  • At the beginning of the line, add a # and a space (#).
  • Save the file by pressing Control-O. When prompted for a file name, press Enter and then use Control-X to close the editor.
  • Reboot your computer.
  • After completing the above steps, try to restore again, this method helps to fix the error in 70% of cases.

    What to do if all else fails?

    Well, now for the bad news. if all the above measures did not help to fix the error, most likely you are faced with a hardware problem. There are three potential culprits here. an iOS device, a computer or a modem. To exclude the last two suspects. connect the i-gadget to another PC that works through a different modem. If the problem is still there, it is definitely “apple” that is to blame, otherwise. the modem or PC.

    How to fix iTunes Error 3194 on Windows 10/8/7 (Tutorial | 2021)

    In the first situation, we go to the Apple repair center, in the second, we continue diagnostics, now we use our PC, but a different modem. if the 3194 does not appear in such a “bundle”, then the modem is broken, but if the bug persists, then its reason. a computer.

    One way or another, if you find that the nature of the error is hardware in nature and have determined who is to blame, we recommend contacting the appropriate service center. Amateur performance in most cases will only hurt.

    TCP / IP address filtering, firewall or security software

    Method four. If your computer is configured with TCP / IP address filtering, firewall, or security software, follow these steps.

    • Disable antivirus software. It is possible that antiviruses interfere with contacting Apple servers for some reason. In such a situation, you need to disable all protection against unwanted software that are available on the computer, including the “native” Windows tools;
    • Establish a direct connection to the Internet bypassing the router. Some routers block iTunes access to the update server. If you are using a non-Apple router try the following.
    • Disconnect your computer from your wired or wireless router.
    • Use an Ethernet cable to connect your computer directly to the modem.
    • Restart your computer and modem. Get instructions on using your modem from your ISP.
    • Make sure you are connected to the Internet by going to
    • Cancel TCP / IP filtering. This is done in the settings of the router connected to the iPhone. The correct solution would be to remove the router from the mowing line of the Internet entering the computer. Simply put, you need to connect an Ethernet cable directly to a PC or laptop through which the gadget is updated.

    I decided to analyze, perhaps, the most popular iPhone error 3194. This error can appear both due to a software failure or a hardware malfunction. In this article, we will analyze different options for solving error 3194.

    To understand error 3194, you need to consider how the iPhone is updated.

    The update algorithm includes the following steps:

    How to Fix iPhone Stuck on Recovery Mode & Error 3194 iPhone Restore Fix

    • By pressing the corresponding buttons in iTunes, a connection is made to the Apple server and a message is sent with a request to flash a gadget connected to a PC or laptop.
    • After receiving feedback, an IPSW file with firmware is downloaded to the computer, which must be unzipped.
    • After that, the gadget switches to recovery mode and re-sends a request to Apple to sign the received and unpacked file with the ECID certificate.
    • Next, the most important thing begins. the iPhone recovery procedure, and the display shows the dynamics of everything that happens.

    By carefully monitoring the iPhone update process, the user should notice exactly when the error 3194 occurred, and, based on this information, take steps to eliminate it. So, if the error got out at the very beginning, when trying to download files and the Apple logo appears on the display, its causes lie in the program’s malfunctions. The error is caused by a hardware problem if it appears when the update is nearing completion and has already been 70-90% complete.

    • You tried to install an older version of the iOS operating system, such as iOS 6 or lower, on your Apple iPhone. This version of the operating system, without JailBreak, cannot be installed. Apple has stopped signing older versions of iOS (now only 7). If you are still eager to install an old version of iOS on your iPhone device, then you will have to do JailBreak, i.e. “Break”, open the file system of your device, this procedure is not safe and can turn your brand new iPhone or iPad into a useless brick
    • The computer does not have an up-to-date version of iTunes.
    • Modified Hosts file on your computer. This file is used to control Internet access for various programs. For example, by writing special lines in this file, you can deny access to any program to the Internet. In this case, as a result of your or not your actions in the Hosts file, entries that block iTunes access to the Internet appeared, thus, when installing or updating the iOS iPhone, error 3194 crashes.
    • Filtering TCP / IP addresses, firewall or security software (antivirus)
    • Antivirus programs. The appearance of error 3194 due to certain actions of antivirus programs is not excluded. In this case, you must turn off the operation of all anti-virus and anti-spyware programs, including those provided by Windows.

    Problems with the device’s modem or its power can lead to error 3194.

    Checking the Internet

    The first thing to do is to check for an Internet connection. iTunes actively uses the network in the course of its work, therefore, we continue to try other options, only after checking the availability of any site. If there is no connection, we restart the router and try again or check with our provider, and therefore there is no access to the World Wide Web.

    First aid

    Despite the fact that each error requires a different approach, Apple Support, first of all, in the event of a bug with any serial number, recommends taking the following “preventive” measures common to all problems:

    • Reset your computer and iOS device
    • Update iTunes
    • Update the software on your computer. if you own a Mac, open the App Store on it and click on “Updates”, if you are a Windows PC user. click on the “Start” menu, then “Programs” / “Windows Update”.
    • Connect the iOS device directly to the system unit if it was connected to a USB hub, keyboard, etc.
    • Disable antivirus software and / or firewall

    It is worth noting that the conflict between software and iTunes, which leads to the inability to contact Apple servers (which is absolutely necessary for updating and / or restoring) is the most common reason

    the appearance of error 3194. That is why it is very important to timely update and correctly configure third-party programs installed on your PC.

    To a greater extent, this applies to all sorts of security utilities that can, for some reason, refer iTunes to suspicious programs and, when it tries to contact Apple’s servers, block it. That is why it is so important to follow the last recommendation. “Disable antivirus and / or firewall”, if iTunes stops giving an error with deactivated security programs, then you just need to adjust their settings by adding “tuna” to the list of trusted utilities.

    TCP / IP address filtering, firewall or security software

    It often happens that the antivirus protection software you are using prevents you from updating or restoring data from your device. Then try deactivating antiviruses and firewalls. Deactivating Windows Firewall can also help. How to do it:

    • in the “Start” menu, select “Windows Settings”;
    • click on the line “Windows Security”;
    • go to the section “Firewall and network security”;
    • click on the active network and switch the position.

    Now it’s worth trying to reflash the device again.

    Everything is standard here. download the file, unpack it, set up contact with the phone. Check the functionality of the socket through which contact is established with the iPhone during reboot. Also, make sure the integrity of the working files.

    Recovering or updating from another computer

    If you suspect that malicious PC files or its inaccurate operation are preventing you from reinstalling the system, try using another computer or laptop as a base. If there is no such thing in quick access, you can contact a specialized center. Now they are in almost every city.

    If you have any questions or complaints. please let us know

    Checking the hosts file

    For iTunes error 3194 to be resolved promptly, you need to clean the host file before flashing. It can be done like this:

    • put the phone into DFU state;
    • iReb choose iPhone (model number);
    • waiting for a message to appear about the possibility of sewing without closing iReb;
    • then hold down ShiftRestore;
    • choose a custom firmware and clean the host file.

    We repeat the reboot attempt after logging out of the account.

    The reasons

    For a more correct understanding of why the error occurs and its fixes, consider the rollback process itself.

    • User downloads iTunes firmware from a dedicated Apple server.
    • Unpacks IPSW archive data.
    • The device is put into Recovery Mode.
    • Checking iPhone update from Apple.
    • A request is sent to the update site.
    • The recovery stage begins.

    Lag occurs after the fifth point, when permission is not received from the server in response to the request for signing the firmware. The reason for this can be hardware or software. To clearly define the ways to fix the bug, you need to understand what caused the failure.

    • software. the error is knocked out before the company logo and status bar appear on the screen;
    • hardware. error 3194 occurs during the firmware process.

    Speaking of the program item, the following circumstances may be to blame for the error:

    • an outdated version of iTunes is installed on your PC;
    • hosts incorrectly paves the way.

    ITunes update

    The old version of the firmware will not allow you to perform all the manipulations. Make sure the OS version is up to date before performing restore and reset on iPhone.
