Lenovo Legion Y540-17IRH bricked, need BIOS

[sect-sin]

Hello everybody,

I have a bricked (after BIOS downgrade) Lenovo Legion Y540-17IRH notebook. Attached is a screenshot of the motherboard version and a dump of the corrupted BIOS. Could anybody provide me with an up-to-date, fixed BIOS file with all DMI information transferred?

I thank you very much in advance for your efforts.

...after BIOS downgrade...

Here is an older (38) version if you need to downgrade from the current (44) one for some reason. The DMI location as already mentioned by Peste.

hoaca388, peste & Vesko356,

Thank you very much for the quick reply. I will try to program the BIOS today with the files you attached & will let you know about the outcome.

I think I will try the most up-to-date version first, and go to earlier versions if required.

Hi masters, I have
Legion Y540-17IRH (81Q4)
SN: PF28T3J0
MTM: 81Q400G7PB

It starts, in left top corner blinks white underscore 3 times, no Legion Logo, just backlight is on.
I tried to flash hoaca388 BIOS from post #2 and I got artifacts on screen. If I went to bios, "Discrete graphic" option was greyed out, no changes available.
Is it because this bios is for different GPU?
My BIOS attached, can anyone have a look please.

Thanks in advance.
