Apple is flying high in the technology industry for a reason – they produce magnificent products that consumers seem to love every single year. Whether it’s an enhancement in the design, or additional, innovative features, they are always raising the bar which their competitors need to aim for. However, Apple products do still experience problems from time to time.
One of those is an issue when trying to restore an iPhone. The process should be a relatively simple one, as all you need to do is connect your iPhone to a computer via a cable, and Apple should do the rest. But, for some people, the prompt "The iPhone could not be restored. An unknown error occurred (4013)" or "An unknown error occurred (4014)" displayed, either due to a faulty cable, or a poor Wi-Fi signal.
So, we're going to discuss some of the solutions to this all too common problem.
Solution 1: Before Start, Try Apple's Guide
Before you attempt any diagnostics, you should always refer to the official Apple help guide first if you see error 4013, or error 4014 when you restore your iOS device. They'll explain to you exactly what they want you to try.
If that doesn't work, then you can start to explore other solutions.
Solution 2: Make Sure that Your Wi-Fi Works Good
One of the main causes of the error is a poor Wi-Fi signal. Now, you can either follow the Apple guide we talked about above, which has a section about your Wi-Fi. Alternatively, you can just reset your Wi-Fi yourself, if you know how, as that usually allows your internet to regain a strong signal.
If you don't know how to reset your Wi-Fi network, well, it is pretty easy. Just disconnect the Wi-Fi on your iPhone and computer. Then wait a little while to reconnect them to the network. Or, you can connect your iPhone and computer to another Wi-Fi network if you can.
Solution 3: Change the U2 Charging IC
This is a much more complicated venture and does require some knowledge. So, if you are going to try this, then we'd suggest searching for a detailed tutorial on YouTube, so you can watch exactly how to do it.
If you are not sure that you can handle this, don't try this method in case you damage any component but you can read on to find other solutions.
Solution 4: Put Your Device into Recovery Mode
You can also try this Recovery Mode trick which works for lots of iOS issues.
Step 1. Hold the Home button and connect your iPhone to iTunes on your computer.
Step 2. Release the Home button and then you'll see the 'Connect to iTunes/computer' logo on your iPhone – it is in Recovery Mode now.
Step 3. Follow the iTunes prompt to restore your iPhone. Once you see the loading symbol on your iPhone screen, take out the cable straight away.
Step 4. Wait approximately 10 seconds, and then when you reinsert the cable, the restoration process should begin.
You may also need to know how to do if iPhone won't go into Recovery Mode. And if iTunes still shows an error code, there might be something wrong with your iTunes, if iTunes is already the latest version, try to detect and fix iTunes problems.
