If your iTunes is not functioning well, let’s say it is outdated or not supported by your iPhone’s current iOS version, error 4013 is bound to happen too. In most cases, iPhone error 4013 is caused by a software or system issue. However, it can also result from a hardware failure.

It is inconvenient if you have your iPhone but can’t use it. No chatting, gallery, games, etc., you name it. Why not check my focused solutions below for error 4013? All are arranged optimally to give you an easy time.

If you are anxiously looking for a fix, iTunes may come as an option. But it is too complex to use, and you will lose all your data. I would just recommend you go for Mobitrix Perfix (Check this Method) directly, as it is more user-friendly and easier to use. You can also keep reading to decide which one fits you better.

Method 1: Force Restart iPhone While Charging

Most random firmware crashes can be solved with a force restart, or a hard reset; and error 4013 is no different. You can fix it by force starting your iPhone. I will show you how to perform it below.

First, ensure your iPhone has enough battery left. If not, go ahead and force restart it while charging.

To force restart the iPhone follow these steps:

  • iPhone 8, X, 11, 12, 13, 14, 15: Quickly press the volume up button, then the volume down button. After that, hold down the side button until you see the Apple logo, then let go.
  • iPhone 7 Plus, iPhone 7, and iPod touch (7th generation): Long press both the Volume down and the Sleep/Wake button until the Apple logo appears.

This is the official solution from Apple, and no data is lost in the process. However, it is a temporary fix and may not always work. Sometimes you may need deeper types of restore as I will show you next.

How to factory reset an iPhone:

  1. On your iPhone, open Settings.
  2. Navigate to General > Transfer or Reset iPhone > Erase All Content and Settings.

Method 4: Try to Restore Your iPhone on Another Computer

After multiple attempts to fix your iPhone, you still keep seeing the error 4013? Well, maybe it’s an issue related to hardware of the computer you are connecting your iPhone to. If this is the case, here’s what you should do:

  1. Verify the status of your internet. Check if it’s working. Reconnect or restart your Wi-Fi.
  2. Check if there is any third-party software or firewall installed on the computer. Close the software or firewall and try again.
  3. Check the version of your computer and update it if needed.
  4. Connect your iPhone to iTunes on another computer.

Method 5: Update iTunes

You can also fix your iPhone error 4013 by updating iTunes. Steps vary for different types of computers.

iTunes is an Apple-recommended solution. If you choose to fix your iPhone via updating on iTunes, your phone data will not be erased. However, this method has severe disadvantages in fixing your iPhone error 4013, including:

  • It’s only applicable if you’ve used iTunes before.
  • It’s time-consuming.
  • There is no guarantee that iTunes can recognize your iPhone.
  • iTunes is very unfriendly to use, even for people with a tech background like me.

Method 7: Put Your iPhone into Recovery Mode and Restore

If the above methods have not been successful in fixing error 4013, you can try to restore your iPhone in recovery mode using iTunes.

Here’s how:

  1. Connect iPhone with iTunes on computer.

  2. Once connected:

    iPhone 8 or later: Press and then quickly release the button for volume up and volume down. Next, long-press the side button until the recovery mode appears.

    iPhone 7 Plus, iPhone 7, and iPod touch (7th generation): Long-press the button for volume down and the top (or side) button until the recovery mode appears.

  3. Finally, click Restore.

Note that this method may not be your best option, as you will lose all your data. Plus, given that iTunes is too difficult to use, you are likely to end up wasting time but not getting your iPhone fixed.

Method 8: Put Your iPhone into DFU Mode and Restore

The recovery mode doesn’t work? Then the Device Firmware Update (DFU) is your last resort if you are still stuck at error 4013. It is a state that allows your iPhone to interface with iTunes so that it can be restored properly.

However, I must warn you, putting your iPhone in DFU mode and trying to restore it with iTunes is a complicated process, and all your phone data will be lost.

First, ensure you have the updated iTunes version installed on your computer. Then do the following:

  1. Connect iPhone with iTunes on computer

  2. Enter DFU mode:

    For iPhone 6S or earlier: Long press the Sleep button while holding the Home button for like 8 seconds. Release the Sleep button but not the Home button. Keep pressing the Home button until the computer recognizes your iPhone.

    For iPhone 7 or 7 Plus: Long press the Side button while pressing the volume button for like 8 seconds, and then release the Side button but not the volume button. Keep pressing the volume button until the computer recognizes your iPhone.

    For iPhone 8 or newer: Press and then release the button for volume up. Next, do the same for the down volume button. Long-press the side button of the phone. Once you see a black screen, long-press the down volume button. Long press these buttons but release the Side button after 5 seconds while holding the volume down button. Follow the on-screen instructions that are shown.

  3. Select Restore and click OK in iTunes

  4. Press Restore iPhone

Your iPhone will be restored brand new, as the iPhone error 4013 is fixed.

Method 9: Use the Original iPhone USB Cable

At times, if a faulty USB cable is used during updates or restores, an error 4013 can possibly occur. Because if the cable is not working well, your iPhone may be disconnected from iTunes, or your iPhone and iTunes cannot communicate properly. In such cases, my suggestion is to swap the USB cable, preferably with the original one that came with your device.

If this doesn’t fix the error, try connecting your iPhone to a different USB port, or plug the iPhone into a different computer.

The good thing about this method is it is free and easy to use. However, if the error keeps showing, then the issue is not with your USB cable. You should try something else.

Method 10: Free Up Some Space on iPhone

In an event that your iPhone is running out of space, some functionalities may be disrupted. Thus the iPhone 4013 can also occur. Freeing up some space can help you fix it.

So, go ahead and clear some space by getting rid of the unused and unwanted data and applications on your iPhone. You can also remove data that you have backed up elsewhere, like photos, chats, etc.
