Hello , I have a Lenovo Legion Y540-17IRH-PG0 and tryed to downgrade bios from BHCN41WW to BHCN22WW. The laptop went dead, no screen no boot only power buton flashing and keyboard light. I bought a CH341A programer, but i cant find the right bios (16mb) to write. Bios chip is winbond 25q128fvsq 1952. tryed to write 41ww but power buton blinks like 10 times then stops. Can u please hep me. Thanx in advance
