Apple regularly releases updates to its operating system for mobile devices - iOS. You can usually install them without problems, and immediately enjoy the new performance and additional features. But not everything always goes smoothly - during this process there are errors and failures, and even several attempts in a row do not always give results. This can be dealt with in different ways, which we will consider here.
Common iOS 12 problems during update
In general, this version of the system is aimed at increasing stability and reliability. There are no special functional improvements or fancy goodies in it; its main task is to eliminate errors that have accumulated in previous versions. But it's just a program, and it inevitably has its own weaknesses, so you may encounter an error when installing iOS 12. But sometimes the problem can also be due to incompatibility with the device. For example, if you try to install this system on an iPhone 5, nothing will work. Because it can only work on iPhone versions 5S and higher, and not on every iPad model. Therefore, first of all, you need to check compatibility with your device. It happens that everything is fine with compatibility, but the update fails. The most common problems are:
- Requirement to update iTunes when installing from a computer.
- Error 3194.
- An error occurred when checking for an update - the gadget cannot detect it.
- There was a problem with the installation process itself.
They are all solved in different ways, so let’s look at them in more detail. But keep in mind that these are just the most common situations; there are others, more exotic.
Force quit the Settings app.
To resolve the software download issue, let us first force close the Settings and try downloading again.
To force sign out: On an iPhone with Face ID, swipe up from the bottom of the screen and hold. On an iPhone with Touch ID, double-click the Home . You are now in the app switcher. Settings app card up to close it.
After a few seconds, open the Settings , tap General → Software Update to download and install iOS 14.
iOS 12 update error - "You must have the latest version of iTunes installed"
It is not uncommon for the iOS 12 update to fail to install when using the iTunes app. Even if you have updated it to the latest version, you may still get an error message and nothing will work. You can combat this by completely reinstalling the program. First you need to go to Control Panel - Programs and Features and remove iTunes from your computer. After this you need to restart your computer. Then you need to download the latest version from the official website and install it again. After this, the iOS update usually proceeds without problems.
If all else fails
There are also situations when a person repeatedly tries to install a new version, updates, corrects various errors, but all this turns out to be meaningless. In this case, the following method may be effective:
- You need to install a special program called PhoneRescue on your computer.
- Connect the device.
- Launch the program, go to the menu item, where select the iOS Repair Tools section.
- As soon as the service finds the iPhone, it will offer two ways to service the device. It is better to give your preference to the Advanced Mode option, since in this case there will be no data loss.
After this action, possible errors will be eliminated; after rebooting the device, you can try again to install the latest firmware. If this action does not allow you to achieve the desired result, it is recommended to seek help from a programmer.
Error 3194 when installing iOS 12
Sometimes iTunes displays a window with code 3194, and the iOS 12 update fails. This can happen for a number of reasons:
- An antivirus or FireWall may block the utility from accessing the network or Apple servers. Sometimes other running network programs may interfere. Try turning them all off, closing everything unnecessary, leaving only iTunes running.
- iTunes may not have enough permissions to edit files. Run it as administrator.
- In the Windows folder there is a hosts file, which contains servers to which access is prohibited. You need to look at it - it opens in Notepad and should be empty. You can find it in the Windows\System32\driver\etc folder.
- Check the version of iOS you are trying to install - it should be the latest.
Sometimes the installation of an update fails due to hardware reasons - if you are trying to install it on an iPhone less than version 6, or at least 5S. It won’t even fit on a regular 5 model. But special attention should be paid to access to Apple servers and the firmware file - you can download it again from the official website.

Checking for iOS 12 updates fails
If you try to install the firmware directly from the device using the Internet, you may receive the message “Checking for updates failed.” This is especially true for the iPhone 5S and other “old” models. This means that the device does not find the required file on the server, and perhaps cannot connect to the server itself. Note that this is an unreliable method that can be used only as a last resort, when there is no alternative. After all, at any moment the connection can be interrupted for any reason, and then you have to start all over again. You can deal with the error in the following ways:
- Reboot the device. This simplest method can actually “cure” a huge number of software errors.
- Check the availability of the Internet or Wi-Fi network. If they are unstable or have an unstable signal, try a different network.
- If you install the regular version of iOS 12, then there should not be any profiles on the device. For the beta version, on the contrary, a profile is required. Check this match in the settings.
- If all of the above does not help, refuse the over-the-air update and do it using iTunes.
Take into account the excitement that arises when a new version of the system is released. During the first hours, Apple servers are overloaded, the connection to them may be unstable, and sometimes it is not possible to connect to them. Don't try to be the first, wait a little, the first wave of fans will subside and everything will work quickly and well.
iOS 12 update installation fails
This situation with an error message usually also happens when updating via the Internet. How to fix this glitch and still update to iOS 12? It is much more reliable to connect your gadget to your computer and use iTunes. When this is not possible, you can try:
- Reboot the device.
- Check for free memory. If there is very little of it, delete a few games or something else unimportant.
- See how the Internet works, use Wi-Fi.
- In the settings, delete the downloaded update file and download it again.
If all else fails, you still have to use iTunes.
Keep your apple id handy
When there is not enough space to download and other possible solutions to the problem do not help. We are trying to restore access to apple id. This ensures that you will be able to use all Apple services, such as the App Store, iCloud and others.
If you forgot it, then you need to:
- Go to your account page. Click on the “Forgot your password” checkbox.
- On the next page you need to click the same thing.
- Enter your details and your email address. If the entered address does not match, you can try with another mail.
Unable to verify update - iOS 12 failed verification
This kind of mistake is not uncommon. It appears after installing the new firmware and reports that there is no Internet connection and the test failed. This error when updating iOS 12 can occur for various reasons:
- The Internet really doesn't work.
- The installed version is outdated and its signature does not work.
List of devices that support iOS 12
The first step is to reboot, and if the problem persists, check the Internet from the browser. If it works, then the problem may be with the provider - some put Apple servers on the list of prohibited ones and it is impossible to connect to them. Try connecting to a Wi-Fi network with a different provider. If everything is fine with the Internet, but the error has not disappeared, it means that your firmware version is already outdated, and Apple has already released a more recent version. This happens if you download the firmware and try to install it after some time - the updated iOS system does not pass the test and the iPhone displays a message about the lack of Internet. Then there is only one way out - download the latest version and install it.
Why Apple shows a message about the lack of Internet in such different situations remains a mystery. Even if the firmware signature verification fails, this error appears in the window, only confusing users. Of course, there are other situations, with other types of failures; we have considered the most common ones. Share your cases in the comments and how you solved the problem - this experience will certainly be useful to someone.
How to Update iPhone via iTunes
For those who prefer native tools to third-party ones, the option remains with iTunes or Finder, depending on the operating system you use. I will explain using the example of Finder from new versions of macOS. It performs exactly the same function as ReiBoot, with the only exception that the standard Apple utility cannot fix problems without deleting data.
You can update your iPhone either through iTunes or Finder
This method is suitable if the update simply does not download to the iPhone. But if it downloaded, but for some reason the installation process stopped, you will need to act differently, namely, resort to the recovery procedure. It consists of completely deleting data from the iPhone and installing the most current version of iOS on a clean device.
If the update works, try restoring your iPhone
After this, you will only have to restore the data from the backup copy, which you should have taken care of in advance.
