    Unlocking
    HP - ProBook, EliteBook, ZBook (including 32MB models)
    Chromebooks from all various manufacturers
    Apple - everything older than T2
    More to come...

    Information display (helps to verify file integrity)
    HP - ProBook, EliteBook, ZBook (up to 16MB models for now)

    Custom logo removal
    HP - ProBook, EliteBook, ZBook (up to 16MB models for now)

    Usage: Drag and drop .bin file to .exe file.

    In case there are problems with unlocking your laptop, write a short description of the issue, upload original file and if possible, _unlocked.bin file aswell. Just crying for help is useless. Keep the topic as clean as possible.

    You may ask for feature requests, I'll see what I can do.
    i got this problem sir hello im from PH

    There is a possibility to recover from this latest disaster yes, but it will involve more work as you`ll have to fill new DMI info, thats another challenge. When you get the new chip let us know.

    .
    My CH341A arrived. After modding it to 3.3v I have successfully removed the bios password for my first system with RCUnlocker and NEO Programmer. I can confirm the 8 Pin 25B127DSIG is the correct chip to flash.

    Here are some notes if anyone else is a novice like me:

    1: For this model RCUnlocker just displayed "Unlock Success"
    2: I used the GD25Q127C profile in NEO Programmer as there isn't one for the chip.
    3: In NEO-Programmer I had to select all 5 options for write IC - Off-protect, Erase, Blank Check, Write, Verify. Without this selected it would not write.

    You have only posted the main bios, there is another chip , not sure if thats also 32MB or 16MB, but there is one somewhere on the board, maybe on the other side, when you find it post the backup.

    I have 3 Elitedesk 800 G6 SFF PC with password locked BIOS.

    Product Number (same for all 3): 8YM57AV
    Serial Numbers: CZC1239T57
    CZC1239T5L
    CZC1239T3X

    The boards are all the same revision (Cersei Rev A)

    There are two chips near the BIOS markings (Images Attached):

    8 pin Giga Device 25B127DSIG
    16 pin 25B256DFIG

    I have a programmer on order, it only has 8 pin test leads.

    Can you confirm the 8 pin 25B127DSIG is the chip of interest to RCUnlocker and that the tool works with this model of computer?

    Thank you.

    Here is attached m'y dumped file before patching.
    It's not a problem if it doesn't show the DMI information.

    HP Clean VSS2 dumps,fix Endpoint Security error
    by SMDFlea
    Just a thread to post clean VSS2 files/dumps in.A clean VSS2 file can, in some cases, fix
    the infamous **"Endpoint Security" error message.
    Be aware that if you use a clean VSS2 you may need to fill in missing DMI info using HP BCU !

    I`ve included some clean files/dumps,offsets and a few scripts to autopatch a few models.
    The offsets and file sizes are part of the naming convention i`ve used for the extracted
    files.

    hoaca388 has made an excellent guide how to extract the VSS2 file and edit/clean it up by
    filling everything after...
