[vilmar27@hotmail.com]

Hello,
Please, anyone have the MPM Unlocked BIN File for HP PRODESK 400 G6 Desktop Mini PC?

I have two units that after Windows Update corrupted the BIOS, now I try to power on, but the units show 2.2 Beeps Codes and not complete the POST, the Windows Updated applied BIOS update in these units and corrupted. (I tried many times the Bios Recover process with PenDriver, but not worked).


Serial: BRJ2412YRJ & BRJ2412X4M
Part: 6Z772LP

Hi, Hoaca388!
Ops, for this unit have no password, now I only need to unlock the MPM to replicate this BIOS BIN file to other two units that corrupted the BIOS and no complete the Post, show 2.2 beeps. (I posted it in 5-21-2024, 06:38 AM).

It is posible replicate this BIN file from one unit to other two units and change the BIOS Serial Number?

Thanks a million,
Vilmar

Hi, Hoaca388!
Thanks a lot.

This BIN file removed the BIOS information as Serial, SKU, Feature Byte, Build ID, but not turn on the MPM and I cannot edit the informations.

Manufacturing Programming Mode
Unlock
*Lock

Could you help me?


And also is posible edit the MAC Address for each unit to avoid have 3 units in same network with same MAC Address that can cause mac conflit.

I really appreciate if you help to find these two below information in the BIN file that I can edit with information of each machine?

Integrated MAC Address 1
30-24-A9-FC-0A-F9

MS Digital Marker
010000000000000001000000000000001D000000504E3743562D594B37514A2D504D5744572D56504238382D47564B4354

Is there anything specific I should do differently to properly read the BIOS off this motherboard?

BIOS Chip = GD25B256D

- CH341a black board with the correct drivers installed
- I'm using Neoprogrammer 2.2.0.10 configured to GD25Q256
- Using a SOP16 clip with the following pin mapping: Summary:

• BIOS Chip Pin 2 (VCC) -> CH341a Programmer Pin 8 (VCC)
• BIOS Chip Pin 10 (VSS) -> CH341a Programmer Pin 4 (VSS)
• BIOS Chip Pin 7 (CS#) -> CH341a Programmer Pin 1 (CS)
• BIOS Chip Pin 8 (SO / IO1) -> CH341a Programmer Pin 2 (MISO)
• BIOS Chip Pin 15 (SI / IO0) -> CH341a Programmer Pin 5 (MOSI)
• BIOS Chip Pin 16 (SCLK) -> CH341a Programmer Pin 6 (SCK)
• BIOS Chip Pin 9 (IO2) -> CH341a Programmer Pin 3 (WP)
• BIOS Chip Pin 1 (IO3) -> CH341a Programmer Pin 7 (HOLD)

- PSU disconnected from the main board, and I've tried with both CMOS battery IN and OUT.

However, Neoprogrammer is telling me "IC not responding" which indicates to me that I'm doing something wrong... The machine itself blinks a couple of error codes with its status led as soon as the CH341a is connected.

Any hints?

Hi, Hoaca388!
Now worked fine and the MPM is unlocked.

Thanks a million for help. You is the BEST!

Please, could you help me with more these information?

I need to replicate this BIN file to other two below units that are with corrupted bios and not complete the POST, but I want to save the original MAC Address and MS Digital Marker befoure apply this BIN file in these units. (It is to avoid network conflit if replicate same MAC Address in more units in same enviorement....).

Serial with corrupted BIOS: BRJ2412YRJ & BRJ2412X4M
Part: 6Z772LP

It posible read these two information from bad bios units and replicate this information in this BIN file that you changed? Similar of below information.

Hi did you manage to read the chip?
Having the same problem, if yes would you mind to share?

Re: HP ProDesk 400 G6 Desktop Mini PC BIOS Password Help

RCUnlocker is designed to deal with 16MB files not 32MB files. If you want to do it by yourself, you have to compare between locked and unlocked files till you learn. Otherwise you can upload the file in a proper thread, and someone will try to help you.

What is this supposed to mean? Where we can read how to do it by ourself, any information?

I have the same PC and I am trying to remove the password but the RCUnlocker says wrong chip and to find 16mb, but this is the right one, same as the user above.

I bought the 1.7 version of the CH341 Green Programmer.
After 2-3 hours of manually connecting the cables and checking against the chip scheme, I finally managed to read the BIOS—or at least I think I did.
It seems like the connection with the clip is a bit unreliable, which was probably causing most of the issues. Some pins might not have been working properly either.

One more question. How to find the password and decrypt it, is there info somewhere what they use? Any tips and hints?

Thank you!

Serial No: 8CC1270DH6
Product No: 47L40EA#ABZ

Also I don't have in the list of IC the same chip: GD25B256DFIG

I am reading it as:

GD25LQ256C-1.8v with AsProgrammer 3.15 -> 32.0 MB
GD25LQ256C-1.8v with AsProgrammer 2.0.4-> 32.0 MB
GD25Q256 with NeoProgrammer 2.2.0.10 -> 32.0 MB
GD25B512ME with NeoProgrammer 2.2.0.10-> 64.0 MB

Reading with and settings:

Ch341A Programmer V1.7 1.8V Level Shift with the default settings for 3.3V

Thanks for the help.
