    Thank you, but it doesn't work. When I plug the battery and CMOS there is white charging LED and amber lights on F keys. Amber lights turn off and whilte charging LED blink 8 times. After that I can't power on the laptop. I don't know why, I flashed your bin file with AsProgrammer.

    The chip is GigaDevice 25B256DYIG and I use GD25LQ256C_1.8V to flash it.
    EDIT : IT WORKED! That was my fault, I didn't know that I have to erase IC before write the bin file. All is OKAY 😁 Thank you Hoaca388. Can you explain me (here or DM) the solution please? I really want to learn it! Thank you by advance.

    first boot press f10 apply factory defaults and restart, 2nd boot reset security settings to defaults and exit.
    use BCU. you can permanently disable Absolute lock in BCU.

    Thank you for your help,
    read the rules..https://www.badcaps.net/forum/troubl...before-posting

    post the S/N, the original bios of the laptop, the motherboard model, etc.

    you need an SPI programmer..here is a video as an example...https://www.youtube.com/watch?v=DWWigscuQDY
