After completing the last step, you can now easily remove the motherboard.

Plug in your soldering iron and set it to approximately 350°F.

Be cautious to avoid burns, and always use a proper stand. Keep the soldering iron away from flammable surfaces.

Flip the motherboard over and carefully desolder the small holes using the tip of your heated soldering iron. This will melt the solder, allowing you to remove the USB-C port.

Position the new USB 3.1 Type-C 16-pin female connector in place, then reheat the solder to secure it to the motherboard.
