Steps:

1. Open iTunes.
2. If you’re using a Mac, click on “iTunes” in the menu bar and select “Check for Updates.” If you’re using a Windows PC, click on “Help” and then select “Check for Updates.”
3. Follow the on-screen instructions to download and install any available updates.

Once iTunes is up to date, attempt the restoration or update process again.

Method 3: Use a Different USB Cable and Port

A faulty USB cable or USB port can be a common culprit behind iTunes Error 4005. Try these steps to rule out USB-related issues:

Steps:

1. Disconnect your iOS device from your computer.

4. Reconnect your iOS device and attempt the restoration or update process again.

If the error persists, move on to the next method.

Method 4: Disable or Configure Firewall and Security Software

Firewall and security software can sometimes block iTunes from connecting to Apple’s servers, leading to Error 4005. To resolve this, you can try temporarily disabling or configuring your firewall and security software. Keep in mind that this may vary depending on the software you’re using, but here are some general steps:

Steps:

1. Open your firewall or security software settings.
2. Look for options related to program or application permissions.
3. Find iTunes in the list of applications and ensure it has full network access.
4. If there’s an option to temporarily disable the firewall or security software, you can try that as well, but remember to re-enable it later for security reasons.

After making these changes, attempt the restoration or update process again.

Method 5: Check Your Hosts File

The hosts file on your computer can sometimes interfere with iTunes connecting to Apple’s servers. You can check and edit the hosts file to ensure it’s not causing Error 4005. Here’s how:

Steps:

1. Open a file explorer window (Windows) or Finder (Mac).
2. Navigate to the following location:

• Windows: C:\Windows\System32\drivers\etc\
• Mac: /private/etc/

1. Locate and open the “hosts” file using a text editor with administrator privileges.
2. Look for any lines that include references to “gs.apple.com.”
3. If you find such lines, delete or comment them out by adding a “#” character at the beginning of the line.
4. Save the hosts file.
5. Restart your computer.

After making these changes and rebooting, try restoring or updating your iOS device in iTunes.

Method 6: Check for Hardware Issues

If you’ve tried all the software-related methods and iTunes Error 4005 still persists, it’s time to consider the possibility of hardware issues with your iOS device. Hardware problems like a malfunctioning battery or faulty motherboard can lead to errors during the restoration or update process.

In this case, it’s advisable to contact Apple Support or visit an authorized service center to diagnose and repair any hardware issues. Be sure to backup your data before handing over your device for repair, as some hardware repairs may involve data loss.
