What Is Error 0xe80000a and Why Does It Occur?
Error 0xe80000a typically appears when there’s a communication issue between your Windows computer and your iOS device. It means that iTunes is failing to recognize or connect to your iPhone or iPad. The causes can vary, including:
- Outdated or corrupted iTunes software
- Faulty lightning cables
- USB port or driver issues
- Conflicts with Apple Mobile Device Drivers

Fortunately, this is a well-documented problem that can be fixed using a number of proven methods outlined below.
Solution 1: Restart Everything
This may sound simple, but a reboot can often resolve unexpected software conflicts. Do the following:
- Disconnect your iOS device from your computer.
- Restart your iPhone or iPad.
- Restart your computer.
- Reconnect the iOS device and try again.
If the error persists, move on to the next step.
Solution 2: Update or Reinstall iTunes
Using an outdated version of iTunes is a common cause of error 0xe80000a. To fix this:
- Visit the official Apple website or Microsoft Store and download the latest version of iTunes.
- Uninstall your current iTunes version from your system.
- Install the newest version you just downloaded.
Make sure you’re also running the most current version of Windows and iOS available for your devices.

Solution 3: Check USB Connections and Cables
Sometimes a poor connection can cause your iOS device to not be recognized. Here are some things to check:
- Try a different USB port on your computer.
- Use an official Apple-certified USB lightning cable.
- Avoid using USB hubs; connect the device directly to your PC’s port.
- Inspect the lightning port on your iPhone for dust or debris.
Switching cables or ports can drastically improve connection reliability if the hardware is the root of the issue.

- Scroll down and locate Apple Mobile Device Service.
- Right-click, select Restart.
