With iTunes, you can access your device and manage its operating system through the iTunes interface. The process requires physical connection between the iPhone and the computer. Given that both devices are properly connected, iTunes should be able to communicate with the iPhone. But for some reasons, other users of iPhone 7 Plus have some troubles doing so as they are prompted with an unknown error 0xE. As a result, iTunes does not recognize the iPhone even with the device is already connected to the computer via USB cable or connector. And since iTunes could not read or detect your iPhone, you won’t be able to update or restore your device as well.

Basically you can’t proceed with either processes in iTunes. What causes this unknown error to occur and what is preventing iTunes from recognizing your iPhone 7 Plus even when it is already connected to the computer? Read on to find out the answer to this question and find out the solution.

Possible triggers of unknown error 0xE in iTunes?

The computer and your iPhone must be physically connected to carry out iTunes operations like iOS update or restore. Normally, when the iPhone is attached through USB cable or connector, the computer promptly recognizes your device. Once your iPhone is recognized, you’re all set to use iTunes. But when an unknown error 0xE shows, things will be different. As the error message implies, this iTunes error tells you that something is preventing the computer from recognizing your iPhone even if it is already connected. As a result, iTunes will also not be able to access or communicate with your iPhone. In most cases, the error has something to do with a broken connection between the iPhone and the computer due to a faulty USB cable or damaged USB port on the computer. To determine if this is what’s causing your trouble, try to isolate the problem by using a different USB cable or use another USB port.

There are also other cases where both the USB cable and USB ports are working perfectly but something in the computer system is denying access to the iPhone. Security software like firewall or antivirus are most likely the culprits. When enabled, antivirus and firewall may not grant permission for your iPhone to access the computer system for security reasons. The moment your iPhone is attached to the computer, it will be recognized as an external media. If the security software on the computer that this external device (your iPhone) is posing some threats, access will automatically be denied. External devices are tagged among the main sources of viruses and malwares that are used to screw up the system’s normal function. And to prevent this from happening, security software will act accordingly. As a result, the computer may not be able to recognize your iPhone even if it’s already connected or recognized it but just couldn’t grant access. To determine whether the computer’s security software is to blame or causing the unknown error 0xE to occur, try to temporarily disable antivirus, firewall, and other security suites on your computer and then connect your iPhone again without them. Keep them disabled until you’re done updating or restoring your device in iTunes.

Aside from security software, system conflict is also another factor to consider in this case. This can be the root cause especially if you are using an out of date or obsolete operating system on the computer or using an older or unsupported version of iTunes when trying to manage your iPhone 7 Plus. The system requirements are likely not met and so neither iTunes nor the computer can recognize or access your iOS device. That being said, try to verify and ensure that your computer is running the latest operating system either Windows or Mac OS X, and also use the latest version of iTunes. If necessary, download and install the latest iTunes version for your computer by heading to the iTunes services section on the Apple Support page.

How to fix unknown error 0xE in Tunes?

The solutions that are highlighted in this post are standard or generic solutions that are used to address the main issue which is the computer not recognizing your iPhone 7 Plus. These are also based on the possible causes mentioned above. So here are your options.

First Solution: Check all relevant components.

USB cable, USB port, software version, security software and your iPhone are the first things to check and work on when troubleshooting this error. Make sure that there is no damage to the USB cable or USB port. As much as possible, use only the Apple-supplied USB cable or connector. Try to use a different port on the computer to determine if the previous port is working or not. Once ensured that both the USB cable and ports are okay, check the software version for iTunes and the computer. Make sure they are updated. Security software on the computer also need to be checked or disabled temporarily. Try to connect your iPhone without any security software running on the computer and see if it will be recognized this time. Be sure to turn on your iPhone when you connect it to the computer. Some computers may not be able to detect your iPhone if it is turned off. Finally, check the computer and make sure it is working fine. If you have other available computers, try to connect your iPhone 7 Plus to a different computer. Doing so will help you determine whether the problem is isolated to the previous computer you are using.

Second Solution: Restart the computer and iPhone.

Sometimes, problems like this occur due to some minor glitches on the computer system, iTunes or iPhone itself. And to rectify these glitches, all you need is a reboot on the computer and the iPhone too. So try to restart your computer and then your iPhone 7 Plus. In the case where the unknown error 0xE has caused your computer to freeze, just do a long press on the Power button of the CPU until it turns off. If that won’t work either, just unplug the CPU power cord from the outlet, plug it back in, and turn on the computer.

  • To restart your iPhone 7 Plus, just do the usual way. Press the Power button until the phone reboots.

If necessary, you can do a force restart by pressing and holding the Power and Volume Down buttons simultaneously until the Apple logo appears.

Third Solution: Check the USB device drivers on the computer and reinstall if necessary.

USB drivers are necessary for certain components to work with our computer. For example, a USB driver must be installed so that the computer will be able to detect and work with USB devices the moment they are attached to it via USB connection. Without the correct driver, the component may not work as intended.

If you are using a Mac computer and it does not recognize your iPhone 7 Plus when trying to use iTunes, try these:

  • 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 7 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. 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 are using a Windows computer, reinstall the Apple Media Device USB Driver and then try to connect your iPhone 7 Plus again. Here’s how:

  • 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 to the computer and then open iTunes.

If your iPhone 7 Plus is still not recognized and you still get the unknown error 0xE, try the next possible solution.

Fourth Solution: Check the Device Manager and make sure AMD USB driver is installed.

Another driver that needs to be installed on a Windows computer for your iPhone 7 Plus to communicate with the computer is the Apple Mobile Device USB driver. It has to be installed and enabled on the computer’s device manager. Here’s how you access and reinstall this driver if necessary:

  • 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, 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.
  • 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 7Plus to the computer again.

If the AMDS won’t start or stops unexpectedly, the problem is likely triggered by a third-party security software on the computer. The 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.”

Fifth Solution: Reset Lockdown folder on your Windows computer.

Protected data and hidden folders that contain temporary data mostly related to the syncing of Apple devices with iTunes, are usually stored in the Lockdown folder. The Lockdown folder is present in all computers with iTunes program installed. To erase corrupted data that caused iTunes errors like the unknown error 0xE, resetting the Lockdown folder can help. Follow these steps to reset the Lockdown folder on your computer:

  • 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 7 Plus.

Sixth Solution: Uninstall iTunes and all its components.

In the case where the computer is able to detect your iPhone 7 Plus but your device is not seen or included in the iTunes list, the problem is most likely within iTunes. It’s possible that iTunes or its components get corrupted and caused you this error. Given the fact that iTunes is comprised of several components, it is hard to pinpoint what exactly went wrong. As resolution, you can uninstall iTunes and reinstall iTunes on your computer. Doing so will erase any corrupted data or errors from the iTunes directory and give iTunes a clean fresh start. Here’s how it works:

  • 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 successfully installing iTunes, reboot your computer then connect your iPhone 6s to the computer again and see if the error is already gone.
