Firmware 1.36

I remember reading a few messages about this topic including a discussion with user Clipfan7.

That is exactly what I did as dragged it manually into the root of the sport. Unplug and it updates but doesn’t update the firmware or in this case downgrade it.

I never learned through this Forum whether Clipfan7 was able to downgrade to Firmware 1.28  from FW 1.29.
Made me wonder if each new Firmware prevents reverse updating ??
