I used your way to downgrade the bios version for my t440s thinkpad from 2.54 to 2.36,
but when I reboot, the screen shows "Safe Flash Authentication Failed" and it turns off automatically.
I made sure that "Secure Rollback Prevention" in the BIOS is disabled.

You don't need to reboot. It will reboot itself.
