Part 1. Why Did iPhone Error 4014 Occur?
Why does your iPhone go wrong when you try to restore it? Under this condition, it usually matters to 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:
Part 2. Workable Solutions to Repair iPhone Error 4014 on iPhone 6/7/8/11/12/13
Way 1. Check Your USB Cable/Port
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.
Way 2. Check out 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.
Way 3. Download 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.
Way 4. Clean up Your Device
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.
Way 5. Restart Your iPhone and Computer
I believe that many people will choose to reboot their devices no matter what issues occur. As a result, restarting can solve most normal scenarios.
Way 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.
