    Hello guys!

    I've read a lot here, but unfortunately I can't get any further. Actually I only had one problem with my BIOS, then unfortunately I destroyed two contacts when unsoldering the main chip, so I haven't found a way to read it yet.

    For this reason I bought two new chips. These also work and the notebook is running again, but I have no idea how to activate MPM. Because the DMI information is incorrect and I cannot change it. When booting, the error always appears that there is a problem with the Security Device Unit.

    Since I can't get to the data from the main chip or don't know whether it's possible because of the broken contacts, I only have a backup of the original EC available. I have a backup of the new bios, but I don't know if that helps.

    I read something about this bin file that you copy onto a USB stick and boot from, but unfortunately this doesn't work. Then I read that you have to set the region to a valid one, but what exactly can I do to move forward?

    It's about an HP Elitebook 850 G5. Have already found all the data:

    Serial Number : 5CG85179YC
    Product Number : 3JX60EA
    Description : HP EliteBook 850 G5
    BID=17WWCSBT602#SABD#DABD
    3X476J6S6b7B7H7M7Q7W7m7saBaEapaqauawbUbhcAdUdpdqfAfXgdhKhkjh.ym
    try to write DMI data with this..

    You would need to replace VSS region with clean VSS or just unlock mpm. And after that, enter DMI in bios (SN, feature byte, mac address etc). This will get rid of endpoint error.

    SMDFlea Ah great thanks so much for the script. Will try it tomorrow. Will the change in the EC bin cause any issues with the security endpoint error? I ran into that issue and wasn't sure what to change in the Main bios to fix that.

    Just trying to understand how to use this tool. What is the .bin file. How to generate that .bin file
    you need a SPI programmer..here is a video as an example..

    Works with all with a 32MB EC. Its quicker using a hex editor though.

    SMDFlea in the thread it says 440 g8 will this script work for 450 G8 as well? And what about others 32MB models.

    Hi does anyone know the correct way to remove a bios password off of a HP with a 32MB ec chip? I have 20 ProBook 450 G8 laptops that need to be unlocked for a client. I have had success in the past using RCunlocker from rhetoricalcheese on 840 G6 and 840 G5 but the tool only works on 16MB ec chips not 32MB.

    I could ask someone to unlock a bin file for me but I need to do this over 20 times so I need to learn the method.

    I have a working unlocked MAIN + EC bin from another laptop if that helps

    I tried to flash those working bins to a unlocked laptop and used some tool to change the dmi info to match the serial but the laptop doesn't boot so I assume I can't do it that way. Please help!

    The charging LED being perm lit suggested to me that the bios isn't being read (faulty ic maybe)
    And so I've tried the one before once more with a new IC it worked fine. Thank you both for your help

    I split the main bios the lower part is the one containing the PW it's 16MB so now I can use your script on it
    Well the file I get in the output is the same as the original, I compare both they're identical
    any suggestion how to clean it SN#5CD3291R3D MB: DAX9SFMB8A1 REV:A
    first boot press f10 reset bios to factory defaults and exit, 2nd boot reset security settings to daults and exit.
    you can disable permanently the absolute lock in BCU tool.
    here's your DMI info. use bcu:

    Serial Number: 5CD3291R3D
    Product Number: 6J5H9AV
    CT Number: PREBK068JIB04V
    Description: HP EliteBook 645 14 inch G9
    build_id: 22WWTPCZ601#SABF#DABF

    Or use this HP BCU TOOL ( BIOS Configuration Utility) to fill the DMI info
    The laptop is not booting anymore only charging LED is permanently lit
    what tool did you use? RCUnocker? IDK why it didn't work for me I'm confused
