@castravete
Can you boot in Windows?

Sure. I was trying to use the bios update tool provided by hp.

  1. Download Intel CSME System Tools v10 and unpack it.
    2. Go to Intel ME System Tools v10.0 r8\Flash Programming Tool\WIN64 and run in command line with administrative rights:
    fptw64 -bios -d bios.bin
    Make a screenshot of result.
    3. Give me file bios.bin in zip

I cannot put a link to the bin file since I am a new member. Maybe after this post :slight_smile:

Good. Now run:
fptw64 -a 0x650000 -l 0x40000 -d test.bin
If all OK, then run:
fptw64 -a 0x650000 -l 0x40000 -f test.bin
Make a screenshot of result.
Give me file test.bin in zip

Well. As I thought…
Download UEFIVAR and run in command line with administrative rights:
uefivar -l -bd
Make a screenshot of result.
Add all created *.bin files to zip and attach.

13

nothing
C:\Users\andre\Downloads\Uefivar>uefivar -l -bd
Uefi subsystem not found.
C:\Users\andre\Downloads\Uefivar>

Can you boot from other disk in UEFI-mode? E.g. from USB-stick?
I need any EFI-shell

BTW: Cogito ergo sum

15

I will try to find out how to do this.
regarding cogito / coito - there is a twist - coito/coitus

thanks

Otherwise you will need read/write BIOS by a hardware programmer.

17

I found no way to boot to uefi it beeps and nothing loads W10 as normal. Also in advanced in debug there is no restart in uefi/firmware mode available

18

Bad news. You can’t reset the password without EFI-shell. E.g. GRUB
So only a hardware programme can you.
