    Looking For Working BIOS of LENOVO LEGION 5 15ITH6

    LENOVO LEGION 5 15ITH6
    S/N PF2SAXHJ
    MTM 82JK0001CC

    The laptop won't boot. It restarts over and over again, because a hidden BIOS setting - BLCK, was changed from 100 to more than 120+.
    Need a working bios

    Attached files are original dump files from two separate chips on the laptop, and also the BIOS installation file from Lenovo. Wish it helps.

    Thanks!

        Thank you so much, it works!!

        Following is what i went through using the provided Bios files to fix the laptop, if anyone is interested in the process.

        Background: I had no experience on flashing bios using programmer at all.
        Programmer: CH341A
        Flasher Application: NeoProgrammer

        Two Bios Chips.
        16MByte Bios Chip: XMC - XM25QH128AHIG
        8MByte Bios Chip: WINBOND - 25R64JVSIQ

        Somehow I could not find any application which can detect the XMC chip. However, I selected a random model name with configuration 128 Mbits/16 MByte/256 Page, specifically, W25Q128xV from NeoProgrammer application, and flashed the chip successfully.

        Initially, I failed to flash both two bios chips no matter what flash app I use, these applications can both write and verify at the same time, but they always fail for verification. Then I disabled the verification process during flashing, but still failed to write the bios file to both chips properly.
        Fortunately, I managed to flash the bios chips by erasing the bios chips completely first before trying to write&verify.
