same, same error code.

[danito]

it is also my first laptop to which I am trying to remove the password (I mean ITE/MEC).
I don't know where to start to understand something.

try all for test
------------------------------
After analyse and compare, it seems that you need 00s and not FFs
try final test

it is too short, it must be 256kb I think so

[volinakis]

if it has ITE, just ERASE it, power off, remove programmer, power on and wait. EC will be written by bios which has EC region inside it. Then use LMU to write DMI.
