BIOS HP ZBook Firefly 15.6 inch G8 Mobile Workstation 6050A3216701 -MB-AX1 ( S1 )

Please;
I have the HP ELITEBOOK 850 G8 6050A3216701-MB-A01(A1) motherboard that with the original BIOS does not start at all (only 7 flashes in Mayus Lock) but with the other BIOS that I attached it starts with an image but does not detect SSD.
Can you do the rebuild for me?

Everything is now working correctly, detecting the NVMe drive, but I keep getting the error:
"HP ENDPOINT SECURITY CONTROLLER PROBLEM"
Why?
 
Hi,

I have a laptop, specifically a HP Zbook Firefly 15 G8 (525F9EA#ABU) that I am trying to remove the power-on password (not BIOS setup password) from.

I have tried RCUnlocker, but this specifically looks for a 16MB image, whereas I can't seem to find any 25Q128's or similar on the board, only 2x 25Q256's and several 25Q8's. I have dumped both of the 25Q256's, these are attached.

The file labelled primary.bin is what I believe to be the main BIOS as it is nearest the CPU has the most in common with typical BIOS images I am used to seeing, The file labelled secondary is from the back side of the board, I believe this is the backup that it restores from, presumably in some kind of compressed/archive format as it doesn't appear to have as much data as a typical BIOS image.

Both of these dumps report invalid UEFI volume when trying to open with UEFITool, I dumped each chip twice and got the same MD5 each time.

If it makes any difference, these were dumped out of circuit using flashrom with a CH341A.

Any help with bringing this board back to life would be very much appreciated!
