The patch won't work if the bios version is latest. use this bin flash both it won't work if you only flash the main you should Flash Both.
first boot press f10 apply factory defaults and restart, 2nd boot reset security settings to defaults and exit.
use BCU and put your original DMI.

Good evening, I have this HP 640 G9. It turns on, displays video, and then reboots. It doesn't enter setup or the operating system. It only displays the HP logo. When I press F10, it prompts me to enter the BIOS, and then reboots.
Could any expert please help me fix or remove a BIOS password?
I tried post by rex98, and it does the same thing.

Your bios is U75. If you flashed both of the U75 rex98 bios and it`s not working i`d say it`s a hardware problem
