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. Samus will typically come to rest at horizontal position $29. From here it is possible to roll from pressing left to pressing diagonally down-left to enter the transition, though this will create heavy lag and Samus will not be able to stand in the next room. Alternatively, only briefly press diagonally down-left and then press up, bringing Samus to a stop further left, typically at one of three positions $19, $1C, or $26. If Samus stops at position $26, then the process can be repeated to move closer to the door again, with a possibility of reaching position $19. If Samus then stops at positions $19 or $1C, then rolling from left to down-left will bring Samus into the transition in a pose that will be able to stand, and at horizontal position $15 (as far right as possible). If Samus stops at position $17 or closer, the setup will have to be started over. If needed to transition further to the left, it can be done from position $1C by rolling from left to down (with a brief down-left input), to result in a transition at a position of $14 or less.
