    Not a bios problem. it seems that a assembly issue. Again thanks for your bios file.

    Need unlocked BIOS dump for W25Q64FV (Admin Password removal)
    by dell_bios
    Hi everyone,
    I'm working on removing an administrative BIOS lock (Supervisor/Admin Password) on a laptop.
    The board has three SPI flash chips:
    - W25Q64FV (main BIOS)
    - W25Q32FV (EC/TPM)
    - W25X10CL (configuration)

    I was able to read the dump from the W25Q64FV chip, CRC32 = 0x3DE23E27.
    The dump contains protection that needs to be removed.

    If anyone has a clean or unlocked BIOS dump for W25Q64FV, I’d really appreciate it!
    I’m also happy to share my dump for comparison if needed.

    Laptop model: [please specify, e.g....

    [REQUEST] ASUS TUF A15 FA506NF (2021) - Clean BIOS dump needed (UEFI Password locked)
    by ArkzG
    Hey guys, I have an "ASUS TUF Gaming A15 FA506NF (2021)" that's locked with a UEFI password, I need to reprogram the BIOS chip but can't find a clean ".bin" file for this specific model, I've tried the official BIOS updates from ASUS support page, but they're 32MB updaters that don't extract to a usable 2MB .bin file for direct chip programming.

    What I currently have available:
    - Model: FA506NF (2021)
    - BIOS chip: GD25LQ16 (16Mbit/2MB)
    - Tools: CH341A programmer ready to use

    Does anyone have either a clean 2MB .bin dump of this model,...

    HP Omen 15-dh0052nf power-on & bios password
    by Nopslide
    Hello everyone, I come here to tell you my problem regarding the power-on password. It is not a bios reset demand, and i can't have any access to windows. This is the bios and power-on password that is blocking all other things.

    My Omen 15-dh0052nf purchased second-hand was configured with the bios password upon purchase (very simple password :P ).

    Having decided to sell it in order to get something more powerful, I reset all BIOS settings and set a blank administrator password. But the power-on password cannot be changed to a blank one so I let the actual password set....
