[Solved] How to Fix iTunes Error 2015 on iPhone Without Losing Your Data (Updated: 2023)

For iOS users around the world, few applications have held as much importance over the years as iTunes. However, despite its popularity and robust functionality, users have occasionally encountered errors that can be perplexing and frustrating, especially when trying to downgrade their device.

One such error is the dreaded iTunes Error 2015. This is a strange one because not even Apple knows why it occurs, and instead, they simply call it an unknown error.

If you’ve ever been confronted by this error message, fear not, for this article is here to guide you through the troubleshooting process, offering multiple solutions to help you overcome the hurdle.

Understanding iTunes Error 2015: What Is It?

iTunes Error 2015 is an issue that typically occurs when users attempt to update, restore, or sync their iOS devices, such as iPhones or iPads, through iTunes.

It can manifest itself through a pop-up message that reads, “The iPad (or iPhone) ‘Device Name’ could not be restored. An unknown error occurred (2015).”

This error can be quite puzzling since it doesn’t provide specific information about the underlying cause. A quick search on Apple’s support page also yields no results. However, there are several potential culprits that might trigger this issue.

Potential Causes of iTunes Error 2015:

Network Issues: A malfunctioning or unstable network connection can interfere with the update or restore process, leading to error 2015. All iOS devices communicate with Apple’s TSS server to get a restore ticket before doing any firmware updates or restores. If the ticket cannot be obtained, this will make the restore fail.
Security Software: Overly aggressive firewall or security software settings might prevent iTunes from communicating with Apple’s TSS server, causing the error.

Outdated iTunes Version: Using an outdated version of iTunes can lead to compatibility issues and trigger errors during device management. Usually, major iOS versions require new iTunes versions and updated drivers.
USB Port Problems: Faulty or incompatible USB ports, cables, or connectors can interrupt the data transfer process between the computer and the iOS device. It’s less common nowadays, but a non-MFI-certified cable can be problematic and cause interruptions.
Third-Party Software Conflicts: Background software, including security or system optimization tools, might conflict with iTunes operations.

Jailbreaking: For users who have previously jailbroken their devices, lingering modifications and altered system configurations can contribute to errors like 2015. This is especially true for older devices that used jailbreaks based on modified IPSW files.

9 Solutions to Fix iTunes Error 2015

Before proceeding with any troubleshooting steps, it’s wise to back up your iOS device to ensure your data’s safety.

In order to avoid losing any data, perform a backup in iTunes or your favorite iOS backup tool before trying any of the fixes below.

Solution 1: Check Network Connection and Disable VPN

A stable internet connection is vital for successful device management via iTunes. Ensure you have a reliable connection and consider temporarily disabling any VPN services that might be interfering with the connection.

Solution 2: Update iTunes to the Latest Version

Always make sure you’re using the latest version of iTunes to minimize compatibility issues. Visit Apple’s official website to download and install the most recent version.

Solution 3: Check Security Software Settings

Security software might inadvertently block iTunes from accessing Apple’s servers. Temporarily disable any firewall or security software and attempt the update or restore process again. Remember to re-enable the software afterward.

Solution 4: Try Different USB Port and Cable

Faulty USB ports, cables, or connectors can cause communication errors. Connect your iOS device to a different USB port and use an Apple-certified cable.

Solution 5: Close Background Applications

Background applications, especially those that interact with your device or internet connection, could interfere with iTunes. Close unnecessary applications before attempting to update or restore.

Solution 6: Update Your Computer’s Operating System

An outdated computer operating system might also lead to errors. Make sure your computer’s OS is up to date and compatible with the version of iTunes you’re using.

Solution 7: Hard Reset Your iOS Device

Perform a hard reset on your iOS device by pressing and holding the Sleep/Wake button along with the Home button (or volume down button on newer iPhones) until the Apple logo appears. Then try the update or restore process again.

Solution 8: Put Your Device in Recovery Mode

If other methods fail, putting your device in recovery mode might help. Connect your device to your computer, open iTunes, and follow the instructions to put your device in recovery mode. You can then attempt to update or restore your device.

Solution 9: Deal with Jailbreak-Related Issues

For users who have previously jailbroken their devices, reverting to the original, non-jailbroken state might be necessary to resolve iTunes Error 2015. This can involve restoring your device to factory settings or using specialized tools designed for removing jailbreak modifications.
