All the stones on the white face - Lycée Vicat (Souillac) Lycée Żmichowska (Varsovie)

Consider a game board with $n$ columns and $m$ rows. In each square, there is a stone with a white face and a black face. Every time a square is chosen, all the stones around except the one chosen are reversed. With that rule and starting from a situation where all the stones are on the black face, is it possible to reverse all the stones on the white face ?
