    These are the only thing I have look at the image.

    That's why I'd ask if jumpering the pinouts directly will be also work? I'm afraid to damage the BIOS chip if I overheated the chip with hotair workingstation/blower. We are far from suppliers and other technicians if I damage the chip I can't find a replacement.

    I am planning to reset or remove the bios admin password of HP 640 G9. The bios chip of this laptop is flat unlike other units that has spider pins and this I my first time repairing hp elitebooks bios.
    I hope someone provided me a clear answer, I also would like to know what programmer is compatible for hp elitebook 640 G9 to read&write?

    My 1st experiments with a cheap CH341A programmer + clamp + old hp EliteBooks.
    The clamp is indeed pure horror at times and probably wont last very long.
    But RCUnlocker works like a charme!
    Thank you so much!

    Hello,

    I am trying to remove the BIOS password from an HP 260 G2. I extracted the BIOS from the computer, but whenever I load it into RC UNLOCKER, the error "MISSING UNLOCKABLE CONTENT" appears.

    I have tried for hours to overcome this issue and am at a loss as to where the problem might lie. Could someone give me a hint to guide me towards the origin of the problem so that I can overcome it?

    Thank you.

    I have an HP EliteBook 830 G8 (ProdID: 6A3M6AV / SN: 5cg2145d1p).
    I tried the software, but I got the following error message when launching: "Missing file destination argument!"
    Is the software compatible with my PC please?

    I also see that I will need to make a BIOS backup. Is this possible via software, or do I have to solder a module on the chip?

    Thank you in advance

    Hello all,

    I have an HP Elitebook 645 G10 with a BIOS password. It only has a 32MB WSON8 chip, no 16MB chip anywhere. I can not use the RCUnlocker tool to remove the password since it only works with 16MB chips. I uploaded my dump if anyone has any suggestions on what I should do. Thanks!

    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...
