Please do not “play” with this tool without knowing what your doing… it can be very dangerous because it doesnt care the content of what is written.
The CMD is wrong, its fpt -bios -f bios.bin (learn the tool switches)
But the error presented is due to wrong tool version used, Comet Lake is ME v14…
You’re flashing without even knowing or having done a valid system bios/regions backup… if you already done this (A MUST) you would know the correct tool version… so irresponsible.
Get some reading if you please, before bricking a healthy machine:

EDIT: No, i dont do these “unlocks”, make new request post if you want.
