Grapple to the second Grapple block from the bottom (the one partially underwater), jump off from it, morph, and press against the wall to the right. Unmorph slightly before the peak of the jump (a 3-frame window), then immediately use grapple (a 2-frame window) to get stuck standing a pixel inside the second Grapple block. Then jump (to force crouch), angle down, and grapple. 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 minimize lag, when grapple is extended horizontally release all inputs other than shot/grapple; there will still be a bit of unavoidable lag while Grapple is initially extending. Try to get a good first bounce; otherwise heavy lag may be difficult to avoid, and it may be better to retry from the beginning. Pressing right while inside the transition tiles will trigger the transition. Continue holding Grapple through the transition to initiate a teleport in the next room. If it is needed to trigger the transition further to the right (at position 1774), then wait to come to a stop before pressing right. If it is needed to trigger the transition further to the left (positions 1771 or 1773), then hold right while approaching the door. Either way, Samus should automatically be able to stand in the next room (e.g. for an X-Ray climb).
