Can't download firmware when flashing it (certificate signed by unknown authority)

[SantaHey]

When I run wcc -p /dev/ttyACM0 -f -d, I got this output :

Maybe your firmware is corrupted, or you haven't a valid Lua RTOS firmware installed.

Do you want to install a valid firmware now [y/n])? y

I can't flash the firmware, and I can't find any other source to download the firmware manually. Does anyone have any ideas?
