How to Fix iPhone Error 4014 During Update or Restore

by

Getting error 4014 while trying to update or restore your iPhone in iTunes? It’s a frustrating issue that usually means iTunes is having trouble communicating with your device—often due to a hardware or USB connection problem. Here’s a step-by-step guide to help you troubleshoot and fix error 4014.

1. Update iTunes to the Latest Version

Outdated iTunes software can cause communication failures.

  • Open iTunes and check for updates (or use the App Store on macOS or Microsoft Store on Windows).
  • Install the latest version and restart your computer before trying again.

2. Force Restart Your iPhone

Force restarting your iPhone can help clear out glitches that interfere with restore processes.

For iPhone X or later:

  1. Press and quickly release Volume Up.
  2. Press and quickly release Volume Down.
  3. Hold the Side button until the Apple logo appears.

3. Use Apple’s Official Lightning Cable

A faulty or third-party cable may disrupt data transfer and trigger error 4014.

  • Use the original Lightning cable that came with your iPhone.
  • If you’re already using an official cable, try a different one—just in case.

4. Try a Different USB Port or Computer

Some USB ports, especially on older desktops or through hubs, can cause instability.

  • Plug directly into a USB port on the back of your PC or Mac.
  • If that doesn’t help, try restoring on another computer with the latest iTunes.

5. Choose “Update” Instead of “Restore” When Prompted

When iTunes gives you the choice, click Update, not Restore. This keeps your personal data intact.

  • If the update completes successfully, your iPhone should reboot with the latest iOS installed.

6. Check for Computer System Updates

Your computer’s OS may need a security or compatibility update to work smoothly with iTunes.

  • On Mac: Go to System Settings > General > Software Update.
  • On Windows: Use Windows Update from your system’s settings.

7. Still Not Working? Contact Apple Support

If you’ve tried everything and error 4014 still appears, you could be dealing with a hardware issue—especially with the iPhone’s logic board or connector.

Visit Apple Support or schedule an appointment at the Genius Bar for diagnostic help.
