If u had followed those three steps in PokeStock (try using latest version 3.7), u should've got the pokemons form the Nintendo 3ds Link in Unova Link menu...
Use PokeStock BW (Updated for B2/W2!) and edit your save file to get dream radar trio and some other legendary pokemon http://projectpokemon.org/forums/showthread.php?13832-PokeStock-BW-%28Updated-for-B2-W2!%29&p=154326&viewfull=1#post154326
