Is this a new M.2 SSD or the same that worked previously with this logic board ?

Not sure but it is possible that the M.2 SSD has to be included in the whitelist of compatible SSDs to be supported by the logic board.

What is the history of this logic board ? Any liquid damage ?

Inspect the connector area of the M.2 socket. If possible, post pics here for a review.
