The problem solved after extracting EC from EXE file

I will tell you my "adventure" with L14 gen 3 intel: I had 3 pcs, 1st I read SIO without main battery and CMOS batt and all went well, no errors, SVP removed.

At 2nd, being lazy I just removed keyboard to connect SVOD4 (without removing battery and CMOS batt), read SIO, filled same area with 00 and surprise! password still there! I did read again SIO and compared with original backup and noticed that something similar with strings I filled with 00 is starting with adress 3FC62 but it wasn't in original backup. After I filled that section with 00 password was gone! Bottom line, must read SIO without battery and CMOS batt.

Can Computrace be disabled with just a BIOS copy?

Can someone remove the password from a Lenovo ThinkPad L14 21C1 Gen 3, S/N pw‑04ex8q.
I modified the BIOS but there is an SVP data error and I can’t enter the BIOS. The laptop shuts down when I try. Can someone compare the files in the attachment and correct my modifications please
