Hello Dudu2020 you still help to unlock the bios ?

I will try to read the bios from my laptop in the near future because I have the latest version and I have to use the programmer, will I be able to count on your help, I will repay you. I would like to use the full potential of the installed RAM

Hello,

Sorry this is an old topic but my Y700-15ISK is bricked (loop without access to BIOS).
I have CH341A, I connected it to the 2 BIOS chips on the motherboard, this is what shows up on Asprogrammer:
1st chip : GD25Q32 (GIGADEVICE) GD25Q32B (GIGADEVICE) after reading info, all if FFFFFFFFF
2nd chip : GD25B64C (GIGADEVICE) GD25Q64 (GIGADEVICE) GD25Q64B (GIGADEVICE) after reading info, it seems valid.

what's the next step please, and which chip should I overwrite ?

Thank you
