How to Fix iTunes Error 9, 4005, 4014/4013
The Real Problem
Error, 9, 4005, 4013 or 4014 could be due to certain reasons like faulty cable/port or poor Wi-Fi network. On the surface, your iPhone connects to the computer, iTunes recognizes the device but somewhere down the line, iTunes thinks that the cable is not really that good or suddenly Wi-Fi starts ill-functioning. Even your computer may turn out to be the real villain.
Solution #1: Reboot your iPhone
- Disconnect your iPhone from the computer and reboot it. To do so, just press and hold the Home button and sleep/wake button at once for about ten seconds. On 7 and 7 Plus, press and hold the volume down button and sleep/wake at once.
- Once your iPhone has restarted, connect it to the computer again. And try to Update/Restore it as usual.
Solution #2: Check Out the Faulty Cable/Port
- Check out the faulty cable and port as they could be causing trouble as well. Try a different cable and use another port.
Solution #3. Is Wi-Fi Network Working Properly?
- If Wi-Fi is not working properly or it's poor, the update process may get disconnected and therefore you will get the error message. Hence, make sure that you have proper Wi-Fi connection.
- Disconnect Wi-Fi both on your computer and iPhone and try to connect them to the network after some time.
- Give another network a try as well; if it's there.
Solution #4: Clean Up Your iPhone
