Hello Stefan Steff

Yes, I think I did it okay.
The only thing that is not very clear is the MAC address field.
I changed it on the file in the field Integrated MAC Address 1 , I suppose its the correct one

When rebooted, it asked me for the Factory Host-Based MAC Address

I did like on this video https://www.youtube.com/watch?v=O_hL1_ucjjI
but after saving changes, machine came back to initial state.
Turns on , HP logo, and off (caps lock blinks once).
Not booting anymore once again like when it came to me... frustrating

Is it getting corrupted by bad MAC address?

What do you think?
I also leave here the config file I used with HP BCU tool

Any help is appreciated thank you

Hello again,
You did OK...and you can start again from 0

About your config.txt...you can insert your MAC address F8-B4-6A-EE-86-99 at HBMA Factory MAC Address and HBMA System MAC Address.
Like this:

Host Based MAC Address
Disable
*System
Custom
HBMA Factory MAC Address
F8-B4-6A-EE-86-99
HBMA System MAC Address
F8-B4-6A-EE-86-99
HBMA Custom MAC Address
00-00-00-00-00-00

...then I always use this rows at MPM:

Manufacturing Programming Mode
Unlock
*Lock
MPM Counter
1
MPM Lock Readiness
Not Ready
*Ready

...but to be sure if everything is OK I attached a config.txt what I used on another laptop similar to yours.
Try to study and compare the lines what are not clear for you.

Good Luck !

P.S. config.txt must begin with the word "English"
