Hi,

I have a HP Prodesk 400 G6 Mini, there is a password, could you help me remove it ?

I've dumped the bios using flashrom on a raspberry pi using the spi interface.

I've made three dumps and two are identical using diff and can be opened with UEFITool and password confirmed at the "UserCred" location.

Model : HP Prodesk 400 G6 Mini
Serial No: 8CC1241JNS
Product No: 294W6EA#ABF

Also if using a raspberry is not reliable i have a CH341A coming in a few days (and will wait for it in order to flash)

Hey everyone,

I'm looking for a schematic or datasheet for this mini PC. I want to see if I can add another NVMe slot, since my motherboard only has one. If anyone has it, please share. And if you have a motherboard with two NVMe slots, can you send some high-quality pics so I can figure out how to reverse-engineer it and give it a try?

Thanks a lot!

Hi,

as noobie to this please excuse my lack of experience.

I am trying to remove a BIOS password from this machine:
HP ProDesk 400 G6 Mini

but so far I still have no success.
I bought CH341 programmer and decided to give it a try.

The programmer came with 8 pin cables and connectors or whatever everything else is called so I had to buy a new 16 pin cable because the chip which I think is the BIOS is with 16 pins..



I connected everything and downloaded AsProgrammer and NeoProgrammer then installed drivers...

Master need to remove password. thanks in advance...

Biggest cheers to you!!!
With this file I reflashed 2 devices.
This is step by step how I did that.
1 - Run HP BIOS Configuration Utility (BCU) - to backup original ID's.
1.1 - hpbiosconfigutility.exe /getconfig:"backup_id.txt"
1.2 - store it somewhere where you can take it when it need.
1.3 - Edit backup_id.txt, find inside string starts "Manufacturing Programming Mode" replace

1.4 - Save with replace.
2 - Desolder flash from motherboard.
3 - Put FLASH chip to programmer (in my case I used CH341A (green version))...

YEEEHAAA!
Thanks for help for this PC.
The problem why I get 5 long 7 short buzz, is bad flashing.
Change programmer and usb port, reflash - bingo.
PC starts, bios unlocked.
Can you help me with another bios?
