Hello. I need flash for IT8176FN-56A keyboard controller for NM-C371 Rev 1.0 motherboard. Lenovo Legion Y540-15IRH-PG0

Unfortunately, I removed the program and the LED backlight and the entire keyboard does not work.

I've been programming since the y-700, but the function keys don't work properly.

Please help me

Ugh. Same problem here. Tried a BIOS flash hoping it would also update the kbc firmware. It updates the EC but not the keyboard controller. Why is Lenovo using a separate keyboard controller here anyway? :-( No idea what to do now. Can't give it back to customer telling that the keyboard does not work. If somebody has the key to this please share!!

UPDATE! Somehow managed to fix this. Apparantly performing a BIOS update through Windows did the trick! After a firm reboot all keys work now. So I assume kbc firmware is also updated together with kbc and BIOS + ME.
