I have tried on Windows 10 and Mac with similar results.
Hold button in while applying power, release button after a few seconds and the openspot2 starts and loads the update file again and then it says that it is waiting for tx/rx to finish before reboot then when the timer is finished it starts counting again?
I have stopped the upgrade now and I am running v17
What happens when you release the button in the 4th step?
- Unplug the OS2
- Press and hold the button
- Plug in the OS2 while holding the button
- After about a few seconds release the button. The bootloader should upgrade the application with the downloaded firmware file and the LED should blink this way during the upgrade process:

Do you get a yellow LED?
or
Does the LED turn off?
or
Does the app start indicated by the voice announcement transmission of red flashing LED?
or
Do you see the upgrade red/green colors like here:
