When updating ipad error 3194. How to fix the problem

When updating, restoring or downgrading the firmware on Apple devices, error 3194 often occurs. This failure of the program does not allow receiving the requested update files and SHSH hashes (digital signatures) from the server for the current iOS.

The occurrence of error 3194 may be the result of a software failure or hardware failure of the iPhone, iPad. It can be triggered by the computer security software, the inoperability of the router or modem, problems on the Apple servers.

You can determine the causes of error 3194 by the time it is diagnosed:

  1. If it occurs during the restoration of an iPhone or iPad, when the status bar is 2/3 (75%) full, the reason is hardware.
  2. If the notification appears at the very beginning of filling the line, when the display only identifies the Apple logo, the root cause is software.
Error 3194 may be due to a software glitch or hardware failure in the iPhone.

The hardware causes of error 3194 are problems with the power supply and the functionality of the smartphone or tablet modem. It will not work to eliminate them on your own, you should immediately contact the service center. Partial replacement of components, restoration of contact connections or replacement of the modem itself will help fix the problem.

  1. An attempt to change a new version of the operating system to an earlier one. It will not be possible to do this by direct request to the Apple website without JailBreak, because old versions of iOS are not quoted on new devices (it will not work to reflash an iPhone from iOS7 to iOS6).
  2. Modifying the contents of the Hosts file. He is responsible for managing the access of various applications to the Internet. Records blocking iTunes access to the global network may occur unintentionally, the user may not be aware of this. For example, the TinyUmbrella utility, which downloads digital signatures from Apple's server, automatically updates the Hosts file. As a result, requests from iTunes do not reach the update server and cause an error.
  3. Outdated version of iTunes.
  4. Filtering of TCP / IP addresses is installed, the work is blocked by antivirus.

Methods to fix error 3194 triggered by a software crash

Method 1

  • Close iTunes, unpair your iPhone or iPad with your computer.
  • Find the Hosts file on your PC (it has no extension). For Windows OS, the path to it looks like this: C: \ Windows \ System32 \ drivers \ etc \ hosts.
  • Open the Hosts file in a text editor (Notepad, TextEdit).
  • In the stream of characters and lines, find the line with the ending .gs.apple.com. It blocks Internet access, preventing iTunes from functioning properly. You need to remove a line from the file or put a # (ignore symbol) in front of it. Save changes.
  • To activate the changes, you need to restart your computer.
  • Connect Apple device to PC, launch iTunes. If you run the repair process again, the error should disappear.

On Mac devices, you need to follow this algorithm:

  • In Finder, select the "Applications" -> "Utilities" tab.
  • Launch "Terminal".
  • Enter the command sudo nano / private / etc / hosts. Press "Enter".
  • Enter the password (used when logging into the PC), press "Enter".
  • The "Terminal" will display the contents of the Hosts file.
  • At the beginning of the line .gs.apple.com. add the # symbol and a space.
  • Press the key combination Ctrl + O (save the file), Ctrl + X (close the editor).
  • Reboot the system.

Method 2

It consists in using third-party tools to fix the problem. In this case, the TinyUmbrella utility will help you to eliminate alert 3194.


Method 3

It consists in updating the current version of iTunes to the current one. Timely updating of the toolkit of this program allows you to fix a lot of errors that occur during the operation of devices on the iOS platform.

  • Launch iTunes utility.
  • Select Menu-> Help-> Updates. The program will automatically check for updates and offer to apply them.
  • After updating the program, it is worth repeating the operation that caused the error 3194.

If you cannot find automatic updates, you should uninstall the current version of the program, download the newest one, install it using prompts and an intuitive interface. The iTunes.exe installer contains all the required drivers.

Method 4

It is applicable if responses from Apple servers to iTunes requests are not received as a result of incorrect operation of security software (firewall, antivirus) and filtering of packet data protocols by network routers. Find out what exactly caused error 3194? in this case it is difficult, it is worth acting radically:

  • During the recovery of the Apple device, completely disable the security software.
  • Disable protocol filtering in the modem or router settings.
  • Connect the PC directly to the network, bypassing the router (for a wired connection).

After fixing error 3194 in iTunes, you need to run the TinyUmbrella utility, after recognizing the connected device, it will appear in the "Edit" window in the "Recovery Devices" section. Click the left mouse button on this line, then on the “Exit Recovery” icon. Now you can use your favorite gadget as usual.

To prevent error 3194, stay tuned to iTunes for updates and do not try to hack the file system of Apple devices with third-party applications.

If iTunes sends a request to sign the firmware with an IPSW certificate ECID(SHSH blobs) cannot receive a response from the Apple server, then the unfortunate error 3194... Today we will tell you about the ways to deal with this ailment.

There are at least two reasons for this program behavior: 1) Apple has stopped signing old firmware versions. 2) Modification of the "hosts" system file to use the Cydia cache servers.

Correcting error 3194 when restoring (updating) the firmware:

Method 1.
1] Download and install the latest up-to-date version of iTunes. This can be done from the site's office
2] Try to restore the firmware.

Method 2.

3] Uncheck Set Hosts to Cydia on Exit (connect to Cydia servers instead of Apple's).
4] Try to restore the firmware.

Method 3.


Mac OS X - Go ->

3] Open the "hosts" file:


74.208.105.171.gs.apple.com


7] Start iTunes.
8] Try to restore the firmware.

Fixing error 3194 when downgrading the firmware:

Method 1.
Likewise with the first method for restoring (updating) the firmware.

Method 2.
1] Download and install the program
2] Run it and go to the Advanced tab.
3] Uncheck Set Hosts to Cydia on Exit (connect to Cydia servers instead of Apple's.
4] Put your i-gadget in DFU mode - hold the lock button for 3 seconds, without releasing it, press and hold the home button for 10 seconds. Now release the lock button, but keep holding the home button for another 30 seconds. When a gray background appears on the display of the device, the button can be released. iTunes will inform you that your device is in DFU mode.
5] Try to restore the firmware.

Method 3.
1] If iTunes is open, then close it and disconnect the i-device from the computer.
2] Find the "hosts" file on your computer:
Mac OS X - Go -> Go to folder in Finder. / Etc / folder
Windows - C: \ Windows \ System32 \ drivers \ etc - hosts file
3] Open the "hosts" file:
Mac OS X - Using TextEdit
Windows - with administrator rights in Notepad
4] Find and delete the line 74.208.105.171.gs.apple.com
5] Close the file (you need to save the changes on exit).
6] Connect the i-device to your computer.
7] Start iTunes.
8] Put your i-gadget in DFU mode - hold the lock button for 3 seconds, without releasing it, press and hold the home button for 10 seconds. Now release the lock button, but keep holding the home button for another 30 seconds. When a gray background appears on the display of the device, the button can be released. iTunes will inform you that your device is in DFU mode.
9] Try to restore the firmware.

After completing the restore procedure, close iTunes. Find the "hosts" file again and remove the line " 74.208.105.171.gs.apple.com". This way you will be able to update your iPhone / iPad / iPod touch through the official Apple servers.

Also, in the same “hosts” file, after deleting the above line, add “#” before the beginning of all other lines. Then you need to close / save the file and reopen iTunes.

When restoring or updating the firmware on an iPhone in iTunes, an unknown error 3194 is often encountered, which, of course, greatly scares the owners of Apple smartphones. Moreover, it can appear on the old iPhone 4s, and on the "fresh" 7 and 8 models. However, you should not panic and immediately run to the service center. In half of the cases, the situation can be corrected independently at home. The main thing is to know what to do. This is exactly what we will discuss below.

Before we talk about how to fix error 3194, let's dwell a little on the problem itself.

  1. This "glitch" occurs usually when upgrading the device or trying to restore it. Therefore, the pop-up warning about the error is almost the same in both cases. They differ only in one word - "failed restore... "or" failed to renew…».
  2. Error 3194 can be caused by both software and hardware. To understand what kind of problem you have, you need to pay attention to the moment it occurs. This allows you to diagnose the nature of the problem with an accuracy of 90%. So if the error interrupted the process of preparing for the update or recovery, that is, "jumped out" before the branded "bull's eye" and the status bar appeared on the screen of the iOS device, then most likely you are faced with a software malfunction. When a bug makes itself felt when the upgrade or restore procedure is running (when the status bar exceeds 50-60%), a certain hardware problem is usually to blame.
  3. What kind software glitches or situations cause unknown error 3194? Often this is an outdated version of iTunes or a modified system hosts file, which sometimes contains a ban on accessing Apple's servers. Antiviruses and similar programs can also cause an error, as well as the enabled TCP / IP filtering in the router settings.
  4. Most frequent hardware problems that cause error 3194 are associated with the failure of the iPhone modem or with a defect in the operation of the power system. It is difficult to fix them yourself. Moreover, the maintainability of such models as 5, 5s, 6 and 6s is extremely low. It is better to contact a service center, where specialists will carry out qualified repairs. For example, they will restore the contact connections of the modem or replace it with a new one.

For reference! Quite often, error 3194 appears when the firmware is "rolled back". For example, when a user wants to upgrade from iOS 11 to iOS 10.

How to fix error 3194 yourself?

So, if the unknown error 3194 arose due to hardware problems, then you should not take the risk and engage in self-repair. The iPhone has a rather complex device, and if you are not a professional with experience, then most likely you will just seriously damage the device. In the same cases, when error 3194 appears due to software failures, then the decision to try to fix it yourself is more than justified.

What is needed for this? Now let's tell you:

  1. The first step is to restart the iPhone and the computer itself from which you are updating or restoring the device.
  2. Update iTunes to the latest version. You can just uninstall the program from your computer and download the newest version. At the same time, do not download iTunes from "left" and incomprehensible resources. Give preference to the official website.
  3. Update the software on your computer. Nothing complicated here. True, it is done differently depending on the OS.
  4. Disable antiviruses, firewalls, firewalls and other security utilities. Various programs designed to protect against malicious software can prevent the device from communicating with Apple servers during the same device update via aytyuns. Thus, they provoke the appearance of error 3194.
  5. Try to do without a router. That is, simply exclude the device from the "computer-Internet" chain by connecting the cable directly to a PC or laptop. If this is not possible, then at least turn off TCP / IP filtering in the router settings.

Eliminate error 3194 by editing the hosts file

If the above steps did not help, then there is one more option - adjusting the hosts file... We will not dwell on what it is, why this file is needed, etc. We will just tell you what changes need to be made to eliminate the error.

So, if you have a Mac, then:

  1. We close aytyuns.
  2. Open Finder. Next, click on the "Programs" section. After - on "Utilities".
  3. Launch "Terminal" and enter the following command - "sudo nano / private / etc / hosts". The hosts file will open. True, if there is a password on the computer, then you will need to enter it as well.
  4. Now we find the line "gs.apple.com". There will still be several numbers with dots in front of it. As a result, we put a hash "#" at the very beginning (without quotes!) And after this character we add a space. Please note that there may be several such lines. In this case, edit each of them in the described way.
  5. Press "Ctrl + O", then enter and close "Terminal".

If you have a device with Windows, then do the following:

  1. Close iTunes.
  2. We go along the path "C: / Windows / System32 / drivers / etc / hosts".
  3. Open the hosts file. We will use "Notepad" for this.
  4. Find and remove from it the line that contains the address gs.apple.com.
  5. We save the changes. We start rebooting the device.

Now you know what error 3194 is, how to diagnose it correctly and how to deal with it. Feel free to try the recommendations described above in action! Good luck!

Almost every Apple phone owner has encountered unknown iTunes crashes. Among them, the most common is error 3194 when restoring iPhone 4s. It can crash when trying to recover lost phone data from a backup or OS update.

If this malfunction occurs, then you should not immediately give your smartphone to a service center. The problem can be solved on your own without overpaying money. The problem is not critical and can be solved quite easily.

Nobody is immune from glitches in the work of Aytyuns. They can occur at regular intervals, but this does not mean that the iPhone is defective or misused. Malfunctions can occur due to disruption of data transmission through the PC and failure of the router settings.

Error 3194 when restoring iPhone 5s and other models of the line often occurs in two cases - when restoring a device connected to a computer, and when downloading or installing a system update.

A warning appears on the PC screen with the text “Could not be restored. An unknown error occured (3194) ". If the problem occurs while iOS is updating, the warning text will be similar.

Causes of occurrence

All reasons that lead to error 3194 are conventionally divided into two types - software and hardware.

It is easy to understand the source of the failure, it will be enough to start the iPhone recovery process. To do this, you need to download the firmware (IPSW) from the official website and unpack the archive. The smartphone then checks for available updates. The firmware should start, after which the device recovery process will be activated, a logo and a status bar will appear.

An accurate "diagnosis" can be made at the moment of occurrence of the malfunction:

  • if the code appears before the appearance of the corporate logo and the status bar, then it is referred to as software;
  • A problem is considered a hardware problem if it appears somewhere during the flashing process of the phone.

If the problem lies in the device itself (for example, it has difficulties with power supply or performance), then it will not be possible to solve it at home without additional diagnostics. For software reasons, problems with an outdated version of iTunes are also included.

It is easier to fix software malfunctions, but it should be borne in mind that any manipulations with a smartphone can lead to unpredictable consequences.

Software and hardware reasons

Software crashes can be resolved 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 newer, modern devices.

If iTunes does not "see" the smartphone, then the reason lies in hardware failures. These include technical damage to the modem and power outages.

How to fix

Troubleshooting methods depend on the reasons for which it appeared. If the reason is of a hardware nature, then the smartphone must be taken to a service center for detailed diagnostics. It's no secret that Apple equipment is difficult to repair, since parts are often not available for purchase.

If the problems are related to the modem, then you will have to pay for its complete replacement or soldering the contact connections. Specialists from the service center may charge a high price.

If the malfunction is caused by software failures, then you can try to fix them in the following ways.

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.

Checking the hosts file

To remove error 3194 when restoring or flashing iPhone, you need to go to the hosts file. The program writes all the changes and the SHSH hash to it automatically without the knowledge of the computer. Disconnect the device from the computer and exit the iTunes program completely. Open the file with the right mouse button "Open with ...", "Text editor".

A dialog box appears in front of the user, in which he needs to find a line ending in ".gs.apple.com". It is this designation that blocks access to programs. Delete the entire line, leaving the # sign instead.

ITunes update

A software glitch may be lurking in the official app itself. In this case, it needs to be updated. This can be done using the Help - Update menu button. The program will independently check for updates and prompt the user. In most cases, the crash disappears after that.

TinyUmbrella Program

If during the recovery of the device it was not possible to avoid error 3194, then this utility will help you to eliminate it. To do this, you need to download and install it. After that, you need to find the Advanced tab and uncheck the box next to the line "Set hosts for Cydia at the exit".

Antivirus

One of the reasons for 3194 may be an installed antivirus program blocking data transfer. Try turning off the antivirus programs on your PC and see if the error goes away. Disabling protocol filtering by the router can also help. If your computer is connected to the Internet via a Wi-Fi connection, if possible, connect it directly to the network using an ethernet cable.

Conclusion

If all the above methods of dealing with the 3194 code turned out to be powerless, then the right decision would be to take the device to a service center. Diagnostics can be expensive, but as a result, the owner of the phone will receive a detailed answer about all problems with the phone.
