Need Clean BIOS/EC Bin File for Lenovo ThinkPad Yoga 11e - Stuck with 0275 Error CMS

Hello everyone,

I am attempting a repair on a Lenovo ThinkPad Yoga 11e that is currently stuck at boot with the error: "0275 error CMS" even after setup new bios battery and will not allow me to enter the BIOS/Setup.

This is a critical issue that I believe requires flashing the BIOS chip directly using a programmer (e.g., CH341A/RT809H), as standard software updates or resets are not possible.

I have opened the laptop and identified the main BIOS chip...

I need a bios file for a Lenovo Thinkpad P1 Gen 3 laptop, model 20TJS2LA1B.

Can anyone help me find the BIOS file for this laptop?
This laptop is having trouble booting from a flash drive or SSD.
I've updated the BIOS with a file downloaded from lenovo.com, but it still doesn't work.
So I'm thinking of flashing it another way.
