    I think it is Ch341A fault, i tried voltage mod mentioned in this forum but i ripped off one pin, so i ordered Ch341A version where you can switch between voltages, will come back with new dump after i receive it, thank you for your help for now....

    I appreciate your help!

    Is it because of CH341A itself or could it be ASprogrammer?

    I tried two reads with neoprogrammer, but it seems that it also crashes in mid-reading as after read i try detect chip again and it shows that no ic is found.

    It might be that i need volt mod CH341A to read IC properly?...

    Lenovo V110-15ISK BIOS password help

    Hello!

    I need help resetting BIOS password on this laptop.

    Motherboard:

    LV115SK MB
    15277-1N
    448.08B01.001N

    BIOS chip is from manufacturer GIGADEVICE:

    GD25B64CSIG on the IC, datasheet show that it is GD25B64C but

    I got CH341A and read IC with ASprogrammer, it detected two options:

    GD25Q64 and GD25Q64B so i took the dump from GD25Q64 and uploaded here.

    Should i read the other detected IC and upload it as well? which...
