If the firmware flashes and fails, click repeat. Then will pop up a auto-write firmware after a few clicks. This way, the firmware update is completed. Pls note that this need to be fast. Since the it is very short time to indicate you to click the repeat button.

This is what shows when firmware update is complete.
