HP prodesk 600G1 DM bios mod for NVME

Hello, I own an HP Prodesk 600 G1 DM mini PC and I want to install a M2 SSD NVME in the dedicate but without success.
I’m trying to Patch Bios HP 600 G1 DM in order to Support NVME SSD PCIe (Booting). BIOS is already patched but I can’t install it.
When using Intel ME system tool, it show error:
Error 280: Failed to disable write protection for the BIOS space!
Can you help me flash modded bios?
Link lasted original bios: https:// ftp.hp.com/pub/softpaq/sp96001-96500/sp96020.exe
Link modded bios: https:// drive.google.com/file/d/1Bd19JVYB06LXfGxoT7KbmoWG8xqt5dB3/view
Link file biosreg.bin: https:// drive.google.com/file/d/1ixCiFFKui8fbrckVC-K6bf6YhXxRHx9T/view?usp=sharing



I have followed the instructions in
[GUIDE] Grub Fix Intel FPT Error 280 or 368 - BIOS Lock Asus/Other Mod BIOS Flash
My varoffset/varname is 0x97


After boot to grub and change this value successfully to 0x00, i shutdown my pc, and insert jumper to FDO pin in mainboard, then reboot to windows and use this command to flash my modded bios:
fptw -bios -f mod.bin
But the result is: pdr region does not exist
Can you help me?



If everything else went ok, that shouldn’t matter. You should flash it in dos not windows
