fix iphone error 4014

When the latest iOS version is launched, most people choose to upgrade or restore their iPhones. Occasionally, some problems appear. For example, you may find a window to pop up, showing "The iPhone could not be restored. An unknown error occurred (4014)", which means your iPhone doesn't succeed to be upgraded. In the next content, I will explain the reasons of the error and provide you 10 different methods to fix this issue.

Part 1. Why iPhone error 4014 occurred?

Why does your iPhone go wrong when you try to restore it? Under this condition, it usually matters the iOS system itself, some external conditions and the hardware (the USB cable and the computer and the iPhone itself).

There are some reasons as follows:

(1) Your iTunes cannot recognize your device (faulty USB cable/port)

(2) Your Wi-Fi network is unavailable

(3) The iTunes is not the latest version

(4) The storage of the iPhone is not enough

Part 2. 10 solutions to repair iPhone error 4014

  • #1 Inspect your USB cable/port whether connecting your PC successfully

    Sometimes the updating problems are related to the hardware. If the cable cannot work well, then the connection between the computer and the device doesn't exist. Pay attention to the port. Maybe the cable is just loose.

  • #2 Check out the Wi-Fi network

    Poor Wi-Fi network can affect the process to upgrade and even directly interrupt it. We should take this condition into account. If you cannot make sure whether the Wi-Fi network goes wrong, you can choose Reset Network Settings.

    check for network
  • #3 Download and install the latest iTunes version

    Your device is going to update the latest iOS system, so you should first promise the latest iTunes. Or the previous version might have some issues related to the compatibility.

    check for updates
  • #4 Clean up your device to release more capacity

    As is known to us all, the storage is too full to cause the devices to react slowly. The new version is more advanced, and we should guarantee enough capacity.

  • #5 Restart both your iPhone and the computer

    I believe that many people will choose to reboot their devices no matter what issues occur. As a result, restarting can solve most of anormal scenarios.

  • #6 Try another USB cable/port

    If you ensure the hardware has been connected correctly and you still have faulty updating, you should consider changing another USB cable.

  • #7 Use another computer

    The upgrading process involves the USB cable, your iPhone and your computer. Therefore, if you have changed another USB cable but there are still problems, you can try another computer.

  • #8 Put the iOS device into Recovery Mode

    In most cases, Recovery Mode can repair errors. Before taking this method, you should ensure your iTunes is the latest version.

    First, put your iPhone in Recovery Mode. Close iTunes, connect the iOS device to the computer, open iTunes, and force restart it into the mode. Taking iPhone 5s as an example, press the Home and the top key together until entering the Recovery Mode. Second, connect to iTunes in Recovery Mode and begin recovery.
