Do you keep running into an “iTunes could not connect to this iPhone. An unknown error occurred (0xE80000A)” dialog in Windows? Read on to learn why that happens and what you can do to establish a proper connection between the iTunes software and your iPhone.

iTunes’ error code 0xE80000A can show up while connecting an iPhone to a Windows PC for several reasons. For example, it could be a buggy instance of the iTunes app, corrupt iPhone permissions, or even a worn-out Lightning cable. A similar error can also show up while plugging in an iPad or iPod touch.

Work through the following troubleshooting tips to fix error 0xE80000A in iTunes on Windows 10 and 11.

Restart Apple Mobile Device Service

iTunes uses a background process called “Apple Mobile Device Service” to interact with Apple devices you connect to your Windows computer. Restarting it is a quick way to eliminate random glitches that result in the 0xE80000A error. To do that:

Fully Quit and Relaunch iTunes

Another way to fix iTunes error 0xE80000A is to force-quit and relaunch iTunes. To do that:

Repair iTunes to Default Settings

If you use the Microsoft Store version of iTunes, try resetting it to its default settings. However, that may cause you to lose various forms of data—e.g., Apple Music downloads. Your iPhone backups will not be affected. If you want to go ahead:

Run iTunes as an Administrator

Running iTunes as an administrator can fix loads of errors and other issues with the application. To do that, search for iTunes on theStart menuand selectRunas administrator.

If that fixes error 0xE80000A, considersetting up iTunes to launch with administrative privileges always.

Restart Your Windows PC

If the above tips didn’t help, try restarting your PC. That should get rid of minor connectivity issues preventing your iPhone from communicating with iTunes. To do that, open theStart menuand selectPower>Restart.

Change USB Ports and Cable

Malfunctioning or damaged USB ports also result in iTunes errors, so try connecting your iPhone to a different port on your computer. Avoid USB hubs since they don’t provide sufficient power to devices and cause additional issues.

While you’re at it, closely examine your iPhone’s Lightning cable and make sure it’s not twisted, frayed, or broken. Use a different Lightning or third-party MFi-certified USB cable and check if that makes a difference.

Additionally, you may want to consider checking for and cleaning the Lightning port on your iPhone of any dust or lint. Compressed air (do not stick the can’s nozzle inside) or an interdental brush can help.

Reset Lockdown Folder in iTunes

If the iTunes error 0xe80000A persists, rename the folder that stores the authentication information and security certificates of Apple devices on your computer. That forces iTunes to recreate a new folder and helps rule out corruption issues. To do that:

renC:ProgramDataAppleLockdownLockdown.old

Note: If resetting the LockDown folder results in an iTunes 0xE8000003 error, revisit the relevant section above and reset iTunes. If you use the non-Microsoft Store version of iTunes, you must reinstall the app (more on that below).
