On our devices there are more processes running than we are aware of. Some of those processes can cause issues, should they become unresponsive, or interrupted by processes of other apps. Usually, restarting the computer and the iOS device is what you need to do to fix a great number of "an unknown error occurred" error messages, including error 2002.
Restart your computer and iOS device, as a way to terminate the processes running in the background that might have caused this issue, and repeat the process.
Maybe the error code 2002 appears because the iTunes version installed in your computer is outdated. An outdated version won't have all the tools need to update, restore, or sync files to your device. You can update iTunes, either via iTunes itself, or by downloading it from Apple's website.

Resetting the network settings is an efficient way to fix the 2002 error message, because it will purge all the modifications made to Wi-Fi, and cellular data settings, some of which you may not be aware of, and which can interfere with the system update.

In order for a connection to be established, the gold plates of the USB port should touch the corresponding gold plates of the lightning port of your iOS device. That connection is done through the lightning cable. Maybe the USB port where the USB cable is plugged in is broken, which prevents the strong link between the computer and the mobile device. Plug the cable in a different USB port and try again.
Note: If you use a desktop computer, plug the USB cable in one of the USB ports on the back side of your computer, which are part of the motherboard, because it is possible the front USB ports are disabled in BIOS, or the link between them and the motherboard is broken.
Maybe your USB lightning cable is the reason for the "an unknown error occurred 2002" error message. Find another USB cable and repeat the same process. If the error message didn't appear, buy another USB cable.
Note: Make sure to buy accessories from Apple's authorized stores only, as fake accessories might be responsible for more issues on your device.
