Get a boost from a Bomb or Power Bomb while grappled to the top Grapple block below the door; alternatively, do a grapple wall jump instant morph from the third Grapple block, frame-perfect unmorph and grapple to clip a pixel inside the second Grapple block (at vertical position $CF = 207), then crouch and grapple to the second block. 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. Heavy lag can typically be avoided by holding right during the bottom half of the swing. While swinging up, tap up to retract Grapple to avoid the ceiling (or tap up after after coming to rest against the ceiling if this happens). Samus should usually come to a stop one tile in front of the door (at horizontal position 215). Roll from pressing right to pressing diagonally down-right to enter the transition. If it is needed for Samus to be able to stand in the next room, then only briefly press diagonally down-right and then press up, bringing Samus to a stop at position 225 or 227; then roll from right to down-right to enter the transition (at horizontal positon 235).
