BIOS for bricked HP EliteDesk 800 G1 DM business PCs

[KristinaFutur]

Hey guys! I have a couple of embarrassing questions.

Here’s the situation: I have two bricked HP EliteDesk 800 G1 DM business PCs (FRODO Rev.A). Someone messed with the BIOS software, and now when I turn them on, only the fan spins at full speed.
I’m using a CH341 programmer, which connects and reads without desoldering the chip.

The problem: I can’t find the right BIOS dump. Official versions are no longer available. Does anyone have a BIOS dump with a clean ME region, or any leads on where I can find one? I found something that seems somewhat similar, it flashes but doesn’t solve the issue.

Also: I have one identical working PC with a functional BIOS, but I haven’t figured out a safe way to create a proper dump without touching the chip, and I’m afraid to brick it too
