Can I flash the img over even with locked device state?

Yes, power off your phone and do this

[solved] FP3 update 0.12-p-2020100376806 went wrong

Did you boot the phone into Fastboot Mode by starting or rebooting it with keeping Volume - pressed? The fastboot command only works in Fastboot Mode.

fastboot: unrecognized option ‘–set-active=a’

Have you booted into fastboot mode?
