BIOS is not sewn

When I try to flash a BIOS from a bootable DOS flash drive through afudos, nothing happens:

I waited 10-15 minutes, then there is no point, I think (it usually takes a few seconds).
Perhaps the problem is that I'm trying to downgrade the BIOS version from 223 to 219.
I tried to sew through engineering afudos, through the usual early version 2.11, through 2.41.
Is it generally possible to roll back the bios at home?
