Enter immobile with G-mode direct, with the Metroids having been killed previously. Take a Rinka hit to regain mobility. Back up to between 1 and 6 pixels from the door transition, and activate X-ray to get very deep stuck in the door. Climb up 1 screen, moving quickly to minimize Rinka damage. Perform a turnaround buffered spin-jump away from the door to trigger the transition, bypassing any lock on the door.
