Get a boost from a Bomb or Power Bomb while grappled to the bottom half of the turret above the door. Samus will enter a 'glitched grapple hanging' state where Samus' graphics will appear corrupted while swinging with Grapple. Slightly delay the down press to extend Grapple, to avoid getting caught on the corner of the floor. Swing down, and hold left while approaching the door to trigger the transition. Continue holding Grapple through the door transition to initiate a teleport in the next room. If Samus needs to be standing in the next room (e.g. for an X-Ray climb), then be sure to touch the ground before reaching the transition; this can be done by timing the Grapple extension early enough, or, if enough energy is available, by doing a small bounce before going through the transition. Samus can reach the transition at either horizontal position 20 or 21, depending on the specific timing and positioning of the swing. Pressing diagonal up-left just before the transition (to retracting Grapple slightly) can help more consistently reach it at position 21.
