The problem is that the programming connection needs to be done directly on the motherboard.
 
you help is Much Appreciated ….
Is this EC Rom ok for T450 MEC1633L too? because it is belonging to T440!

yes I agree programming connections need to be done first. and I am looking for help on that too.
thanks again

We only care about the motherboard. Many modules use the same motherboard. Understand ??
 
thanks for the quick reply.
I see, yes (T440 and T450) both have the same board (NM-A251). only my question was "would this EC software works with T450".

i found the solution ... you dont need any file ... just read the password file .. and write it back ... the same file .. the password will be gone ... you dont need any file .. it is same with t450 t460 ,, x1 carbon and all :D
