Before getting into these details it is necessary to understand what exactly are the reasons that cause this problem. Normally, it is known that iTunes is the official store for the iPhone where it is possible to download apps, games, themes, listen to music and do other fun stuff. It is one of those central, irreplaceable apps that are a core part of the iPhone. However, there may come a time when the iPhone stops responding when trying to connect to iTunes.

This problem can have its roots in the fact that the USB cable is either damaged, broken or fraying and isn’t able to establish a secure enough connection. One can find another cable and if even that works it may be possible that the hardware issue is related to the USB port.

2. Unlock the Device and Trust the Computer

If you want to make a successful connection between your iDevice and your Computer, you need to trust this Computer. If the Computer is not trusted then you can’t make any transfers or synchronisations. To trust the computer simply connect your device, unlock it and after you see the message “Trust this Computer” tap Trust. Now you can open iTunes and manage your device.

If you have accidentally tapped Don’t Trust then you need to reset the trusted devices by going to Settings -> General -> Reset -> Reset Location & Privacy. After that, connect to the device to the computer and the Trust alert will ask you again to trust the computer.
