Complications updating your iOS may come in the form of the dreaded iPhone Error 4013, which states:

 “The iPhone [device name] could not be restored. An unknown error occurred (4013).

Being stuck without a way to update can leave you without a working phone, and keep you from accessing all the important things you store online there too. 


What is the iPhone Error 4013, anyway? 

Unfortunately, it’s not very straightforward. The 4013 message is relatively vague, and just means your iPhone ran into a complication during an attempted iOS update and cannot proceed. How frustrating! Fortunately, while the cause isn’t always straightforward, fixing the iPhone 4013 error is usually fairly simple.



Step 1: Update iTunes®

It’s possible that you may be receiving this error because your iTunes itself needs to be updated. I know, it feels like we are constantly being prompted to update our different devices, now we have to also make sure our iTunes is updated as well?! Just like any Apple device, the iTunes software must undergo periodic updates as well. Missing an iTunes update can lead to communication issues between your device and iTunes, likely resulting in the iPhone Error 4013.  Thankfully, updating your iTunes application is very easy and quick. 


How to Update iTunes:

Log in to your MacBook and open the App Store®.

At the bottom of the left-hand menu, you should see Updates.

This screen will show you all the applications on your Mac that are due for an update.

If you see here that your iTunes is out-of-date, simply initiate the update and you should be good to try and update your device again. 

If your iTunes is currently up-to-date, try moving on to Step 2.


Step 2: Update macOS®

The next step in troubleshooting your 4013 error message also has to do with a missed update.

This one, though, isn’t just for an application, but for your entire macOS.

Similar to our iPhones iOS updates, Apple sends out macOS updates periodically as well.

A missed macOS update could be to blame for the error message you are receiving when you try to update your iPhone.

This troubleshooting step is easy to do and may resolve any issues you may be experiencing.


How to Update your macOS:

To update your macOS, follow the same steps as you did when attempting the iTunes update.

Open the App Store. Then, on the left-hand menu at the bottom select Updates. Here, you should be able to see if your Mac is in need of an operating software update. 

If you are on a PC, make sure that you are using the newest Windows operating software.

To check, open the Settings menu, then select Update & Security.

From here, select Windows Update. You should see if one is available to you in this window. 


Step 3: Force Restart 

If neither of the options above seem to be working or are not the culprit of your error message, you may need to move on to trying a Force Restart.

The process of initiating a force restart depends on the type of iPhone model you have. Find your model below and follow the instructions listed.


How to Perform a Force Restart on iPhone 11, 12, X, Xs  Xr, 8, SE:

Press and release your iPhone’s Volume Up button, then do the same on the Volume Down button.

Now, press and hold the Side Button. You should then see the Apple logo appear.

Release the side button, and you’re finished. 


For iPhone 7:

Press and hold both Volume Up, Down & Sleep buttons until the screen goes dark and the Apple logo appears, then release both buttons. 


For iPhone 6s & SE: 

Press & hold both the Sleep & Home button until the Apple logo appears. 

Press and hold both the Sleep/Wake button and the Home button at the same time. When the Apple logo appears, release both buttons.

Once you have performed a force restart on your device, you can try updating it again.

If the force restart did not resolve your 4013 error code, please continue on to our next troubleshooting step. Or try the steps listed here on how to fix an iPhone that won’t update.


Step 4: Reconnect Device to iTunes 

If you have been attempting to update your iPhone independently, you may want to try updating it through the iTunes application via your computer. To do this, connect your device to your computer via a USB cord.* A message should pop up in iTunes asking you to select Update or Restore; make sure to select Update. A direct connection to your computer may clear any communication errors that were causing the 4013 error message on your device. 


*Make sure that your USB cord is in proper working order before you start. A compromised USB cord can also cause the 4013 error message to appear when attempting an update, so it’s crucial to use a cord you know works properly.
