Get a boost from a Bomb or Power Bomb while grappled to the top 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. Press up while approaching the door to retract Grapple to avoid bonking the ceiling. After Samus comes to a stop (at horiziontal position 25), roll from pressing left to diagonally down-left to trigger the transition. This method will allow Samus to stand up in the next room (e.g. for an X-Ray climb) and will also transition at horizontal position 21 (as far right as possible). If it is needed to transition further left (at position 20) while still being able to stand, it can be done with by rolling from pressing left to briefly pressing down (with a brief diagonal input in between), which should bring Samus to a stop at position 20; then press left to trigger the transition.
