Changing COM port number
The bootloader requires the COM port to have any number from 1 to 10. If in your
case the COM port has the number 11 or higher, you need to change it to any number
between 1 and 10.
To do so, open the Windows Device Manager and right click on the COM port you
need to modify. Then select the 'Properties' option.
In the next menu, open the 'Port Settings' tab and click on the 'Advanced' button.
