What is the iPhone Error 4013 and Why it Occurs?

iPhone error 4013 is a hardware-related issue that often occurs during the updating or restoring process.

Beyond that, other possible reasons might be software bugs, hardware failure, faulty USB cable, etc.

This section will introduce some useful solutions to fix the iPhone error 4013 issue. If you have other problems with your iPhone, you can fix them by referring to our previous pages like how to fix the AirDrop not working on iPhone issue, Screenshot Not Working on iPhone and iPad, Safari not working on iPhone, etc.

1. Install the latest version of iTunes

As we introduced above, the iPhone error 4013 might be induced by an incompatibility issue. If the version of your iTunes is out of data, it might not be compatible with your iPhone.So you can go to check if your iTunes is an old version. If it is, update it by opening iTunes on your computer > From the menu bar at the top of the iTunes window, choose Help > Check for Updates > Follow the prompts to install the latest version.

2. Force restart your iPhone

Sometimes the problem is a software glitch or hardware failure that can be fixed by a force restart, which can refresh your device's system. The steps of force restarting an iPhone have been introduced in our previous guide on fixing iPhone stuck on emergency SOS. You can check this guide to know more details.

3. Change a different USB cable

A fault connection between your device and computer can also cause this problem. So you can go to check if there is something wrong with your USB cable. If it is damaged, just swamp out the cable for another cable to see if your problem is solved. 

4. Update the system of your computer

Like an older version of iTunes that might cause error 4013, an old version of the computer also can cause this problem. So you can go to check if there is any available operating system. If there is, just install it.
