CROSSHAIR X670E EXTREME. Flashed V 2007 to V 2403 and in FINAL rebooting got a Green Light and Q-code "99", checked the internet without solutions. Power button rebooted and and BIOS came back and was apparently successful...whew...Just in case one should have that experience.
Now if I can figure what the PD_FW_Update Tool V004 does.
