Well, not exactly the last step, but close. I know of no instance where the cutout switches haven't worked. Among my colleagues on the 737, the most often technique discussed if one were to ever to be exposed to this situation is for the non-flying pilot to place his foot firmly on the trim wheel. Works much better than the hand. The trim system is designed such that if the cockpit trim wheel is stopped, the stab itself will not move because of a clutch mechanism that favors the trim wheel.
