ThinkPad T14 AMD Gen 2 NM-D451
Serial Number: PF3LA7KR
MTM: 20XLS0YJ00

please can someone tell me, which region of the EC dump I have to fill with 0x00 in order to remove the BIOS password?

[rumpumpel1]

Based on the comparison between my EC dump and the proper section ($0AR1M00.FL1) of a BIOS update archive I tried to figure out which region contains the password.
It looks like that filling the region (6 lines) starting at 0x000492F0 with 0x00 does the job.
Use this info with care, because I'm not an expert on this.

try ff or 00

It looks like that filling the region (6 lines) starting at 0x000492F0 with 0x00 does the job.

5 lines 0x00049300 --> 0x0004934F

0x00049300 is checksum 45

0x00049310 --> 0x0004932F checksum 8 ( E6 23 42 D0 AF AA A1 8B F5 95 50 D1 AD E5 03 E7 7D 69 C2 7F 70 6E 2B F5 17 C5 9F 23 9C E8 BD 7A) = 45
there are two repetitions so 45 45

not delete other lines
