Here are several steps you can take to resolve error 2001. It’s recommended to try these solutions one by one until the issue is resolved:

Step 1: Check USB Connections

  1. Update iTunes: Ensure that you have the latest version of iTunes installed on your computer.
  2. Update Computer OS: Check for updates on your computer’s operating system, whether it’s Windows or macOS, and install them if available.

Step 3: Inspect iPhone’s Battery

  1. Check Battery Health: On your iPhone, go to Settings > Battery > Battery Health to check if the battery is in good condition. If the maximum capacity is significantly low (below 80%), consider replacing the battery.
  2. Ensure Full Charge: Before attempting to update or restore, ensure your iPhone’s battery is fully charged. This prevents the device from powering down mid-process.

Step 4: Restart Devices

  1. Restart iPhone: Turn off your iPhone and turn it back on. This can clear temporary software glitches.
  2. Restart Computer: Similarly, reboot your computer to refresh the operating system and eliminate any software conflicts that might be causing the issue.

    • iPhone 7 and 7 Plus: Press and hold the Side and Volume Down buttons at the same time until you see the recovery mode screen.
    • iPhone 6s and earlier: Hold down the Home button and the Top (or Side) button at the same time until the recovery mode screen appears.
  2. Restore iPhone: Once in recovery mode, iTunes will prompt you to restore or update your iPhone. Choose to restore. This will reinstall the iOS without deleting your data. Be sure to back up your iPhone before doing this, if possible.

Step 6: Check for Hardware Issues

Service Inspection: If none of the above solutions resolve the issue, it may be a sign of underlying hardware problems. Visit an Apple Store or an authorized service provider for a thorough diagnostic check.

Additional Tips

  1. Security Software: Sometimes, security software on your computer can interfere with the connection to iTunes. Temporarily disable your antivirus and firewall to see if that resolves the issue.
  2. Use Another Computer: If possible, try to perform the update or restore process on a different computer. This can help determine if the problem is related to your computer or the iPhone itself.
