I don't think there really is any moving past the friend zone once a girl has put you there. I'm sure it has happened, but the chances appear infinitesimal. If you find yourself there, it is best to just move on and find other girls (an action which, ironically, might improve your chances with the original girl slightly).
Know your enemy and know yourself, find naught in fear for 100 battles. Know yourself but not your enemy, find level of loss and victory. Know thy enemy but not yourself, wallow in defeat every time.
