Thank you so much, it works!!

Following is what i went through using the provided Bios files to fix the laptop, if anyone is interested in the process.

Background: I had no experience on flashing bios using programmer at all.
Programmer: CH341A
Flasher Application: NeoProgrammer

Two Bios Chips.
16MByte Bios Chip: XMC - XM25QH128AHIG
8MByte Bios Chip: WINBOND - 25R64JVSIQ

Somehow I could not find any application which can detect the XMC chip. However, I selected a random model name with configuration [B]128 Mbits/16 MByte/256...

LENOVO LEGION 5 15ITH6
S/N PF2SAXHJ
MTM 82JK0001CC

The laptop won't boot. It restarts over and over again, because a hidden BIOS setting - BLCK, was changed from 100 to more than 120+.
Need a working bios​

Attached files are original dump files from two separate chips on the laptop, and also the BIOS installation file from Lenovo. Wish it helps.

Thanks!...
