Lenovo ThinkPad E15 Gen2 NM-C771 need dump

Lenovo ThinkPad E15 Gen2

Hi! Could anyone help me with a bricked Thinkpad E15 Gen2 AMD? (Ryzen 5 4500u)
The attached file has been uploaded to this post earlier, and I guess it should work with my laptop model.
The serial number is PF2C8AAJ.

Can't get the bios dump because the previous owner has already tried to write on the Bios without backing it up first... I tried using the attached file with no luck. Laptop starts but I get no picture.

Thanks in advance!

Hi qayyum786, thanks for your reply!
I'm sorry, I made a mistake with the Serial Number... that was from a working laptop.
The correct SN is PF1B2E1L
Could you help me with this one?

no issue. I check both with serial number and both are same
feel free to flash given bios and copy win key from offset given by smdflea
