Lenovo l15 gen 3 21C3 need bios

The laptop was brought in with a BIOS problem and a password. After reading the dump, the information was damaged. I ask for help in the BIOS with a clean ME region. Motherboard 213035-1. Serial number: PW+04e998, Type number: 21c3-0016ge

hi Mate, I have the same problem with the same laptop. First of all, thanks for the bios files. One question, I use the CH341A tool to flash the BIOS. The main BIOS has the chip MX77L25650FMI42A. Unfortunately, the programs for the CH351A tool do not have this chip in the data. did you flash the chips too? If so, how did you solve the whole thing? For completeness, the backup chip MX25L25673G is available from Neoprogrammer. best regards and thank you very much!

Hi Guys
My Laptop most likely bricked due to BIOS...?
Resetting no success.
Now i took out the bios chip out (MX25L25673G) and read the bios in the RT809F ISP Programmer.

Can someone provide me with a working bios to flash on... as a last resort chance...

model: Thinkpad L15 Gen 3
motherboard: ??? (2022/06)
serial number: PW-02H7WX
type number: 21C3-006LMZ

Thank you
