Error 4013 is related to communication as you might have already discovered since you already tried with a different cable. As it has been dropped, you might be in luck and it's just a problem with your charging dock. Check that it has not been dislodged by the fall, but that's difficult as it's secured by the bracket. You can buy a lightning dock, they are cheap and you don't need to fully install it, just secure it to the connector and keep it carefully insulated from the board to avoid possible shorts and try your restore with that. If it succeeds you just have to mount it, otherwise it might be a more serious matter within the logic board.
