    you should not remove the chip if just testing, just put jumper wire and use ISP in rf809f or h.

    Attacks against PC firmware are on the rise. Unfortunately, protecting the PC BIOS and other critical firmware is often not seen as a priority. HP addresses this with our Endpoint Security Controller (ESC), a dedicated chip that validates the integrity of the BIOS and other firmware to enhance the security of every HP business-class PC. The ESC validates that the firmware is not infected by malware before the CPU is allowed to boot. If any corruption has been detected, it will restore a clean copy held in the ESC's isolated flash. HP is the only vendor offering this unique security solution as a standard part built into business-class PCs to safeguard our customers against IT security threats.

    Bottom line is...no matter if you can "unlock" the main BIOS as long as the ESC provide a backup and restore the old blocked BIOS before you can access it...

    can someone test this use the 1st one
    if it doesn't work use the second one.
    you should flash both main and EC
    and let me know if it boots to MPM thanks.

    Tried another way. Basically I've replaced the entire ME Reg part of the BIOS with info from a Firmware recovery file from the HP site. After more than one hour everything was done 👍🏻 Laptop starts and...informed me about the mismatched information and that it's doing a quick recovery ... after two restarts, the password is there of course 😖😖😖 How the h*LL can I stop it from doing this sh*t recovery? I didn't find any cmos battery on this model, the power is out long enough....How does it remember?😢😢😢

    Unfortunately doesn't work 😔 Some error appeared telling me that the BIOS makes some recovery from the embedded memory due to mismatch ID information...only one option and that was to click "OK" , after 2 minutes the laptop restarted and the password is still there. This is so annoying 😖😖😖 Anyway, thank you for helping!

    [REQUEST] Dell G3 3579 BIOS Password & AMI Protected Range/BIOS Guard Unlock
    by zenius
    Hello, I have an old Dell G3 3579 (ST: 2WQ7LP2-8FC8) with a newer 8FC8 BIOS password. I have successfully attached to the flash chip (W25Q128JVSQ) on the motherboard with a CH341A programmer and made several modifications using Intel FIT (e.g., allow software SPI write) without bricking. I was also able to boot to a modified GRUB shell where I attempted to edit many BIOS security related options like BIOS Guard/Lock, Flash Signature Override, ME FW Image Re-Flash, etc.

    Unfortunately, some of these modifications like to Intel BIOS Guard failed because it is fused into the PCH. Also,...

    [Bios Password Unlock Request] [Dell OPTIPLEX SFF PLUS 7020] [8FC8 method]
    by overclocker1786
    Hello I have a dell optiplex SFF plus 7020 with a password that I recovered from e-waste. It is possible to get the password removed via the bios patch method? I managed to dump the 32MB bios chips and would like help patching it to MFG mode so I can clear the password.

    Thanks.

    A schematic would also be amazing if anyone has one!...

    by traxformania
    Hello,

    I'm using TONGFANG "GM7TG7P" model laptop for over 3 years and i'm entering the same bios administrator password everyday. My laptop has Aptio BIOS (American Megatrends, AMI).

    But today it's not accepting my password. I'm %100 sure i'm entering the correct password.

    I'm trying to reset my bios without success.

    I tried :

    -I removed the BIOS battery and main battery. Waited for a long time but it didn't work. They already stated in the user manual that the password will not be reset even if the batteries...

    1. I bought this laptop from flea market, and the seller said that he had never set a password, however here is a password required when pressing F2 to enter BIOS.
    2. And after entering incorrrect password 3 times, there is no any useful information like "recovery code"
    3. I used universal bios backup tool, and dumped 8MB bin file, but hex code after "SystemSupervisorPw" is...
