What causes iTunes error 0xE on my iPhone 6s?

The unknown error 0xE in iTunes denotes that something is preventing the computer or iTunes from establishing connection and communicate with your iPhone 6s. In most cases, the problem lies within the physical connection between both devices like a faulty USB cable or USB port. Other identified factor that can cause similar iTunes error to occur are security software like antivirus or firewall installed on the computer. Generally, the underlying cause is in the computer that is being used when trying to access and manage your iPhone contents through iTunes. So here’s how each of these factors trigger the unknown error 0xE when using iTunes with your iPhone 6s.

  • Faulty USB cable or damaged USB port. As the error prompt denotes, the iTunes error 0xE is telling you that the computer does not detect or recognize your iPhone even if it already connected. One of the possible reasons as to why this happens is because you might be using a defective USB cable or the USB port on the computer you used to connect your iPhone to is damaged. As a result, the computer is unable to detect your iPhone even when it’s already connected to the computer’s USB port.
  • To determine whether or not this is causing your trouble, try to use a different USB cable or connect your iPhone 6s to another USB port on the computer. Also try to remove any other USB devices that are plugged into your computer as they too can somehow trigger conflicts.
  • Security software. In the case where a security software is to blame, there’s a chance that the computer is able to detect your device at first and then the connection gets lost when the security tool detects the external device (your iPhone) and see some security threats. Again, your iPhone will be treated as an external device that is connected to the computer. And part of the main tasks of security software is to bar any possible threats to the computer system. Perhaps it perceives possible risks that is why it’s denying access to your iPhone. As a result, your iPhone has lost communication and is no longer seen or recognized in iTunes. To rule this out from the possible causes, try to disable any security software like antivirus or firewall installed on the computer then reconnect your iPhone without them enabled. If the error does not show up and your computer is able to detect your iPhone without any active security tool, keep it disabled until you’re done using iTunes. You can enable them back anyway. Another option you can consider in this case is to use a different computer (if available). Sometimes, it would be difficult to pinpoint the underlying cause especially if the error persists after disabling antivirus, firewall or other security suite. Other iPhone users who have encountered similar issue when trying to connect their device to the computer found that the problem is isolated to a certain computer as everything works fine when they used a different computer.
  • Outdated system. The software version on both iTunes and your computer also matters. There are times when iTunes on your computer does not recognize your connected iOS device and prompts you with an unknown error 0xE due to an outdated operating system on your Mac or Windows computer. The same thing can happen when using an outdated version of iTunes. To make sure that this is not causing this unknown error to show, verify and ensure that your iTunes and computer software are both up-to-date. Update your computer software and install the latest version of iTunes on your computer, if necessary.

What to do if your iPhone 6s is not recognized in iTunes and how to fix iTunes unknown error 0xE?

Now that you already have some clues on the possible causes of iTunes error 0xE, the next thing to do is check and do the following:

  • USB cable/connector and USB port. Check and ensure that you are using a functional USB cable and the USB port you are using is working. Unplug all USB accessories from your computer except your iPhone and try each USB port to see if one works. Also try to use a different Apple USB cable if available.
  • Software versions. Check and ensure that you are using the latest version of iTunes and operating system of your computer.
  • Security software. If a security software is enabled on your computer, try to disable it temporarily and then connect your iPhone again.
  • Power. Make sure that your iPhone is turned on when you connect it to the computer. If you are prompted with the Trust This Computer alert after you connect your iPhone to the computer, tap Trust to proceed.
  • Computer. Try to connect your iPhone to another computer. If the other computer also does not recognize your iPhone.

Try the following solutions and then see if any of these is able to rectify the problem on your end. Other iPhone users who have dealt with the same error in iTunes were able to fix it by performing these procedures so you might as well consider giving them a try on your end.

First Solution: Restart

Restart your computer and your iPhone 6s. This should be the first workaround to consider. Should the problem is triggered by random system malfunction on either the iPhone or computer you are using, it should be dealt with by a restart. That being said, try to restart your computer. After the computer reboots, restart your iPhone 6s as well. Then try to connect your iPhone to the computer to see if it is now working as intended.

In the case where the unknown error 0xE has caused your computer or iPhone to freeze, a force reboot would be necessary. To do so, press and hold the Power button on the CPU until the computer powers off. Press the Power button again to turn it back on.


  • On your iPhone, a force restart is done by pressing and holding the Power and Home buttons simultaneously and then release both buttons when the Apple logo appears. The iPhone will then reboot.


Second Solution: Check the USB device drivers on your computer.

Generally, USB devices that are connected or attached to the computer will be shown in the USB device drivers directory of the computer. The path may vary depending on the operating system the computer is running on (Windows or Mac). Here’s how to check on this details.

If you are using a Mac computer and your iPhone is not recognized in iTunes, follow these steps:


  • Hold down the Option key on your iPhone screen.
  • Click the Apple menu.
  • Select System Information or System Report.
  • Navigate to the list of items on the left panel.
  • Select USB. Doing so will open a new panel on labelled as USB Device Tree. It contains the list of USB devices that are currently attached or connected to the computer.


  • Look for your iPhone 6s under the USB Device Tree list. If you see it, then uninstall third-party security software because it’s most likely hindering the connection between the two devices. Otherwise, contact Apple Support for other options.

If you are using a Windows computer, reinstall the Apple Mobile Device USB driver or follow these steps:


  • Disconnect your iPhone 6s from the computer.
  • Reconnect your iPhone after a few seconds.
  • If the iTunes program opens, close it.
  • Press the Windows logo and R keys on your keyboard. Doing so will open the Run command. The Run command contains a box for you to enter commands or directory paths to access on the computer.

Third Solution: Check the Device Manager

The Device Manager contains various types of drivers installed and used on your computer. In this case, try to check the Device Manager and see if the Apple Mobile Device USB driver is installed. Here’s how to access the Device Manager on your computer.


  • Press the Windows and R key on your keyboard to open the Run command.
  • In the Run dialog screen, enter devmgmt.msc then click OK. Doing so will open the Device Manager screen.

  • Look for Apple Mobile Device USB driver.


If you don’t see the Apple Mobile Device USB driver or you see Unknown Device instead, try to connect your iPhone to your computer using a different USB cable or connect your iPhone to a different computer.

If you see the Apple Mobile Device USB driver with an error, exclamation, or question mark, try to restart the Apple Mobile Device Service (AMDS), disable third-party security software, then restart your computer.

Here’s how to restart AMDS:


  • Close the iTunes program.
  • Disconnect your iPhone 6s from the computer.
  • Open the Run command by simultaneously pressing the Windows logo key and the R key on your computer keyboard.

  • Restart your computer.
  • Open iTunes after the restart.
  • Connect your iPhone 6s to the computer again.


If the AMDS won’t start or stops unexpectedly, it could be triggered by third-party security software. Your security software could be interfering with the computer’s connection with iTunes. Try to remove or disable any third-party security software installed on your computer and try the steps again. Otherwise, work with your security software provider to allow the complete list of ports and services that Apple products use. Restarting AMDS is recommended especially if you are getting an error message saying that, “This [device] cannot be used because the Apple Mobile Device Service is not started.”

Fourth Solution: Reset Lockdown folder.

The Lockdown folder is a protected and hidden folder that contains all kinds of temporary data, mostly related to the syncing of Apple devices with iTunes.

  • Type %ProgramData% into the Run command search box and press Enter.
  • Look for the folder named Apple and then double-click on it. The folder will then open.
  • Look for the folder named Lockdown and right-click on it.
  • Scroll to and click Delete.
  • If prompted, click Delete or OK to confirm action.


Restart your computer and then see if the problem has been resolved afterwards.

Fifth Solution: Uninstall and reinstall iTunes and its components.

Uninstalling iTunes and all of its components is another effective solution to various types of errors when using the program to manage your iOS device. Doing so will remove any corrupted or erratic data from iTunes. Here’s how to uninstall iTunes from the computer and re-install it from scratch.
