What causes the unknown error 0xE to occur when using iTunes for iOS restore or update?

One of the requirements to use iTunes for updating or restoring an iPhone is a secured and stable physical connection between the iOS device and the computer. Both devices must be connected using a USB cable that comes along with the iOS device (OEM). Should both devices are properly connected the computer should be able to recognize your iPhone as an external media device. By then, you should be all set to use iTunes and manage your iOS device using the iTunes media library. But some users are not lucky enough to get these things done smoothly as they ended up being denied by the computer and faced the unknown error 0xE. When this error code shows up, the iPhone has been denied access by the computer to use iTunes. As the alert message implies, something is preventing the computer from recognizing your iPhone even if both devices are properly connected. In addition, iTunes won’t be able to communicate with your device.

In some cases, this iTunes error occurs due to a faulty USB cable or damaged USB port. The computer won’t be able to establish connection with your iPhone because there is no physical contact in the first place. Or the computer might be able to detect your iPhone at first but then gets disconnected. This likewise results to an unstable or intermittent communication between iTunes and your iPhone 6s Plus.

Meanwhile, some people are prompted with the same error when using a computer with security software activated. Antivirus or firewall usually denies any external device from accessing the computer system especially when security threat is perceived. The moment you connect your iPhone to the computer through USB connector, your iOS device will be recognized as an external device. If an antivirus, firewall, or other security tool sees potential threats from the external device, access will automatically be denied. Bugs, malware, and computer virus are usually found in external devices so it’s normal for security software to limit or restrict these devices from penetrating and eventually ruining the normal system functions of the computer and all the programs installed including iTunes.

System conflict is also another factor to consider in this case. The use of obsolete operating system on the computer or using old or unsupported versions of iTunes will likely cause conflict when it comes to meeting the minimum system requirements for iOS devices especially those running in iOS 10. Neither the computer nor iTunes is able to read your iPhone and therefore prompts an unknown error 0xE. As much as possible, use only the latest iTunes version and operating system for your computer. You can download the latest version of iTunes software from the iTunes section of Apple Support page.

Potential solutions and workarounds to get rid of iTunes error 0xE

Below are generic solutions and suggested workarounds used by other iPhone users who have dealt with the same unknown iTunes error 0xE when trying to restore or update an iOS device through iTunes.

First Solution: Check physical connections and components.

As mentioned earlier, a loose connection between the computer and your iPhone 6s Plus is a possible reason why your iOS device is not recognized in iTunes or by the computer. That being said, you can start working on this aspect. Carefully check and ensure no damage to the USB port you are using. You can try other ports to see if that will work. Also make sure that your USB connector is working. If you have other compatible USB connectors available, try to switch between USB cables. Doing so will help you isolate whether or not the problem is due to a faulty USB cable in use. Once you have ensured that everything is good with both the USB cable and USB port, try to check what version of operating the computer and iTunes are running on. Make sure they are updated. If that won’t work either, try to disable security software on the computer and then connect your iPhone again. Finally, check and make sure that the computer you are using is working fine. The unknown error 0xE can also be isolated to the computer. To rule this out from the possible causes, try to use a different computer available.

Second Solution: Reboot the computer and your iPhone 6s Plus.

There are times when an external device won’t be recognized by the connector the first time they are attached. Unless there’s problem on the USB cable, USB port, or other relevant components, everything should work as intended. But then again, there are times when random software glitches are the culprit. As remedy, you can reboot the computer and your iPhone. Doing so will rectify the glitch and gives both devices a clean fresh start. After the reboot, connect your iPhone to the computer again and see if it’s working fine now.

You can reboot the computer the usual way or do a long press on the CPU’s power button (if the computer gets frozen from the unknown error 0xE).

To reboot your iPhone 6s Plus, just follow the usual procedure to power it off and then turn it back on. In the case where the unknown error caused your iPhone to freeze, you can do a force restart instead. To do so, just press and hold down the Sleep/Wake and Home buttons simultaneously for a few seconds and release both buttons when the Apple logo appears.

Third Solution: Ensure that all necessary USB drivers are installed on the computer.

Drivers are necessary for computer components to work. A compatible USB driver must be installed for the computer to work with USB devices right from the moment the external devices are attached to the computer’s USB port. Without the correct driver, you’ll be prompted with pertinent errors. In this case, check and ensure that has the right driver that allows USB devices to work on your computer.

Here’s how to view and access installed drivers on a Mac computer:

  • Hold down the Option key.
  • Click the Apple menu.
  • Select System Information or System Report.
  • Select USB. A new panel with a label USB Device Tree will then appear. This panel contains the list of USB devices that are currently connected to the computer.
  • Locate your iPhone 6s Plus from the list under USB Device Tree. If you found it, uninstall third-party security software on your Mac computer because it is preventing the computer from recognizing your iPhone.

Meanwhile, if you don’t see your iPhone in the list even when it’s properly connected to the computer, contact Apple Support for other options.

If you’re using a Windows computer, re-installing the Apple Media Device USB driver might be the key to fixing the problem. Follow these steps to check and reinstall the Apple Media Device USB driver:

  • Disconnect your iPhone 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.
  • In the Run dialog box, enter or type the following line of codes:

%ProgramFiles%\Common Files\Apple\Mobile Device Support\Drivers

  • Click OK to continue.
  • Right-click on the file named usbaapl64.inf or usbaapl.inf and select the option to Install.
  • Be sure to install the file that ends in with .inf extension. If you are not sure of which file to install, right click a blank area in the File Explorer Window, click View, and then click Details to find the correct file type.
  • Disconnect your iPhone from the computer and then reboot your computer.

After the computer completes the reboot process, reconnect your iPhone 6s Plus to the computer and then open iTunes.

If your iPhone is still not recognized and you still get the unknown error 0xE, try the next possible solution.

Fourth Solution: Make sure AMD USB driver is installed and shows no error (Windows computer).

Try to access the Device Manager on your computer and make sure that the AMD USB driver is installed and has no error indicators. This driver is necessary for your Windows computer to communicate properly with your iPhone. And for this driver to work as intended, it has to be enabled on the computer’s device manager. The device manager can be accessed and managed through these steps:

  • 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.
  • Scroll to and expand the Universal Serial Bus controllers section.
  • 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, and then restart your computer. Here’s how to restart AMDS:

  • Close the iTunes program.
  • Disconnect your iPhone 6s Plus from the computer.
  • Open the Run command by simultaneously pressing the Windows logo key and the R key on your computer keyboard.
  • Type services.msc in the Run command search box. Doing so will open the services console.
  • Right-click on Apple Mobile Device Service.
  • Click Properties in the shortcut menu.
  • Set the Startup type pop-up menu to Automatic.
  • Click Stop the service.
  • Click Start the service after the service has stopped.
  • Click OK.
  • Restart your computer.
  • Open iTunes after the restart.
  • Connect your iPhone 6s Plus to the computer again.

If the AMDS won’t start or stops working unexpectedly, the problem is most likely triggered by a third-party security software on the computer. That security software could be interfering with the computer’s connection with iTunes. In this case, try to remove or disable any third-party security software installed on your computer and try the steps again. Otherwise, try to work with your security software provider to allow the complete list of ports and services that Apple products use.

Restarting AMDS is highly recommended especially if you are getting an error message telling you that, Your iPhone 6s Plus cannot be used because the Apple Mobile Device Service is not started.

Fifth Solution: Reset the Lockdown folder (Windows computer).

The Lockdown folder contains protected data and hidden folders with temporary data related to the syncing of Apple devices with iTunes. This folder is present in all computers with iTunes program installed. Corrupted data that are stored in this folder can also trigger an unknown error 0xE to occur when attempting to connect your iPhone to iTunes. Resetting the Lockdown folder can possibly get it fixed. Here’s how you do it:

  • Disconnect all Apple devices that are currently connected to your computer.
  • Open the Run command screen by pressing the Windows logo key and R key on the computer keyboard.
  • 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 and that your computer is already able to detect or recognize your iPhone 6s Plus.

Sixth Solution: Uninstall iTunes and all relevant components.

If your iPhone 6s Plus is not shown in the list of available devices on iTunes but the computer is able to detect it, most probably the problem is isolated to iTunes. A recommended solution is to uninstall iTunes and all its components. Note that iTunes has several components thus, it may be too difficult for you to figure out which of these components is the culprit. So here’s what you can do then:

  • Press the Windows logo key and press R key on the keyboard. Doing so will open the Run command screen.
  • Type appwiz.cpl in the Run command search box then click OK. A list of programs installed on your computer is displayed.
  • Right-click on the following programs (iTunes components) — iTunes, Apple Software Update, Apple Mobile Device Support, Bonjour, Apple Application Support, iCloud (individually) and click on Uninstall.
  • Restart your computer.
  • Re-install iTunes by going to the Apple Support website and download the latest version of iTunes for your computer.
  • Follow the onscreen instructions to complete the iTunes download and installation process.

After you have successfully reinstalled iTunes, reboot your computer then connect your iPhone 6s Plus again. See if the unknown error is already gone and that your iPhone is already recognized by the computer and iTunes.

If the unknown error persists and you’ve ran out of options, verify and ensure that your iPhone has the correct date, time, and time zone. Also make sure that you’re logged into your computer as Administrator not as Guest. Otherwise, sign out and switch to an administrative account.
