BIOS for bricked HP EliteDesk 800 G1 DM business PCs

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

No… are you sure?
What other “Official” files then?

2.22 to 2.33 at least…

Intel FPT tool can make several backups of the regions, these can be merged/replace on the full images.

Additional region access for read/write operations can be set by the ME_dis jumper is available.

And a little reading on the forum can be useful…
