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. Continue holding Grapple through the transition to initiate a teleport in the next room. If needing to stand up in the next room (e.g. for an X-Ray climb), then press up while approaching the door to retract Grapple and come to a stop; then roll from pressing left to diagonally down-left to trigger the transition. This method will also transition at horizontal position 21 (as far right as possible). If it is needed to transition further left (e.g. position 19 or 20), it can be done by instead rolling from pressing left to pressing down (with a brief diagonal input in between) and then left again if necessary.
