Great troubleshooting so far. Were you able to complete the steps from If you see an error when you update or restore your iPhone, iPad, or iPod - Apple Support including restarting your computer, testing another USB cable and uninstalling security software?

If so, it would be best to contact Apple Support for further assistance. You can reach out from Get Support or using the direct phone number for your region from Contact Apple for support and service.
