I have problem with my Y580, I was accidentaly installed G580 bios for Y580. Now flashed with right original Y580 bios 5DCN90WW (V8.01), but EC version still remains for G580 5ECN96WW. Due to this fact some functions doesn't work: keyboard backlight and some functional buttons. Already tried to flash with modded bios version from first page, but EC version still remains. I think, that EC change is not included in BIOS file. Could you help me how can I get back EC version to factory? I have attached original Y580 BIOS file 5DCN90WW (V8.01) - it's factory backup from laptop with right EC version. 801BIOS (1).zip
