Grapple to the second Grapple block from the bottom of the room, jump off from it, morph, and press against the Grapple wall to the left. Unmorph slightly before the peak of the jump (an 8-frame window), then immediately use grapple (a 2-frame window) to get stuck standing a pixel or two inside the second Grapple block below the door. Then jump (to force crouch), angle down, and grapple. Samus will enter a 'glitched grapple hanging' state where Samus' graphics will appear corrupted while swinging with Grapple. Press jump to get a good bounce off the wall at the bottom of the swing, making it possible to swing up to the door. To avoid heavy lag, hold down during the bottom part of the swing, and hold angle up during the top part. Samus should usually enter the transition with the ability to stand in the next room. If needing to make sure that Samus can stand, or to ensure the transition happens further to the right, retract Grapple by pressing up while approaching door; then after coming to a stop, roll from holding left to holding diagonal down-left to approach the door at a controlled low speed.
