What is error 14

If you see this kind of message while trying to update or restore your IOS device through iTunes,

“The iPhone [device name] could not be restored. An unknown error occurred (14).”

or

“The iPhone [device name] could not be updated. An unknown error occurred (14).”

then you have arrived at the right guide that will show you how to deal with this issue and manage to update or restore the device eventually. In general, there is no single reason entitled to its appearance. The error may pop due to a number of reasons different in each individual case – badly connected USB cable, outdated software, system glitch, insufficient memory, compatibility issues, and other possible causes as well. Now, let’s hop into the guidelines below. We encourage you to try each step in the sequence offered below until the issue gets finally resolved.

If your device is stuck on the Apple logo and does not want to move any further, skip over to these steps and get to the original sequence of methods after reviving your device.

1. Make sure you have free memory on your iPhone

One of the biggest fundamentals allowing a device to update is available memory. Each update requires space to be downloaded and installed. If there is not enough free memory on a device for the necessary update, then it is more likely to run into a problem like error 14. Thus, make sure you check your iPhone (or other IOS device) internal storage for at least a couple of gigabytes. Here is how:

  1. Go to Settings and navigate to General.
  2. Then find and choose [Device] Storage.

From there, you will be able to see how much memory is left. If there is not a lot of it left and you see barely any free space, then this can be the reason why you are facing the error 14. Empty some space by deleting or transferring unnecessary files to another storage.’

2. Check your USB cable

Another possible reason why error 14 appears could be because something is wrong with your cable. Make sure it is fully plugged into the ports on your Mac (or Windows) and IOS device as well. Try other ports to see if anything changes. Also, if you have a spare cable or someone to borrow it from, try it as well and check the difference. If nothing changes and you continue being trapped by the same error, go to other solutions we have down below.

3. Ensure your iTunes and macOS are up-to-date

When dealing with issues related to updating or restoring a device through iTunes, many users come up with successfully solving the problem by downloading new software updates. This is why we highly advise you to check both iTunes and macOS for available updates and install them if any. Here is a short instruction on how you can do this:

To install updates for macOS:

  1. Go to Apple menu in the top left corner of your screen and choose System Preferences.
  2. Then, click Software update and choose Update Now to install the latest update available for your current version.
  3. If you don’t see this button, this means your system is already up-to-date.

Usually, other apps like iTunes get updated along with installing the latest macOS version. Despite this, it is still worth double-checking.

To install updates for iTunes:

  1. Open App Store from the dock on your screen.
  2. Move to Updates on top of the window or left pane and search for iTunes from the list.
  3. If there are any updates available, you will be able to click on Install to get them.

Otherwise, your iTunes service is up-to-date. If you installed iTunes on Windows from Microsoft Store, do a similar procedure there.

4. Force-restart your device

This is a solution to get out of the Apple logo loop which may be faced by some users. It has become quite common for IOS users to have their devices stuck at the Apple logo while trying to update or restore a device. Here is what you can do to get out of this state and try updating your device using alternative methods again.

iPhone 8 or later:

  1. Press and quickly release the Volume Up button.
  2. Press and quickly release the Volume Down button.
  3. Press and hold the Side button (which you use to unlock your screen) until you see the Apple logo.

iPhone 7, iPhone 7 Plus, and iPod touch (7th generation):

  1. Press and hold the Side (or Top) button and the Volume Down button together at the same time.
  2. Likewise in the previous steps, the Apple logo should appear on the screen.

iPad models with a Home button, iPhone 6s or earlier, and iPod touch (6th generation) or earlier:

  1. Press and hold both the Side (or Top) button and the Home button until you see the same Apple logo as it was above.

iPad models without a Home button:

  1. Press and quickly release the Volume Up button.
  2. Press and quickly release the Volume Down button.
  3. Then press-hold the Power button and wait until the iPad restarts.

Basically, the pattern of restarting your device is the same only varying by a combination of buttons on different generations of IOS devices.

5. Disable TCP/IP filtering, firewall, or security software

Error 14 can be also related to Internet problems. If so, it is worth checking that no third-party security software blocks access to it. Some anti-malware programs may lead to certain incompatibilities stopping proper communication with official Apple services in some cases. Thus, let’s check it by doing the following:

  1. Try to disable your third-party antivirus or other security software.
  2. If this does not help or there is simply no third-party software you can disable, maybe the problem is with your Internet connection.

  3. Restart the router plus computer and reconnect to your wireless network again.
  4. If you are using a wireless Internet connection, try to connect an Ethernet cable directly to your computer (if there is one available). This should also help you resolve the problem.
  5. You can also find another network and try to use it instead.

Summary

Errors that pop while trying to update or restore a device through iTunes or traditional settings are no longer a wonder to the Apple world. Many of them are present and continue their popularity each day. In general, all the solutions we discussed above can be applied to other problems with similar symptoms and rooting. We hope our guide helped you finalize the issue and update or restore your IOS device successfuly.
