thinkpad p53s Bios

[Kind_Drop]

I am in the process of flashing the bios on my bricked lenovo thinkpad p53s. I am using a raspberry pi and a pomona test clip, all is going well and i can read the flash chip as well as remove the old bios but i am having trouble figuring out what file is the new bios. I extracted the .FL1 file from the most recent bios update (n2iuj38w.iso) from the lenovo website. Using UEFITool I can explore the contents of the .FL1 file but I don't seem to know what file to write onto the flash chip. The only file that has the same size required by the bios is the padding. I am pretty stumped so if anyone had any idea on how to proceed that would be greatly appreciated.

You are right to use the .FL1 file, but you have to know where to cut it from. If you need the bios file, you have to post the backup bios file (even if it is corrupted) and the serial number.

My laptop serial number is PF292CDY
And here is the backup bios file

This all started when i made the mistake of putting special characters in my bios password. All that shows up on my computer when I boot it is "0199: System Security - Security password retry count exceeded" Is this the right process I should take and Is my computer recoverable?
