Get a boost from a Bomb or Power Bomb while grappled to the second Grapple block below the door. 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 left while near the top of the swing, and hold angle down for the middle of the swing. 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.
