Gain R-mode while entering the room. Use the respawning bugs to refill reserve energy. Get grabbed by the Beetom and carry it to the 4-tile high gap one screen above the bottom-left door. Position Samus one pixel to the right of being against the wall. Jump and aim down, reaching the ceiling at the same time that reserves are triggered. This will force Samus to stand up, briefly clipping into the wall above. Immediately freeze the Beetom inside the wall, by buffering a shot during the reserve trigger. Use a Ripper to get knocked back onto the frozen Beetom. This will clip Samus one pixel left into the wall, making it possible to X-ray climb. X-ray climb up 2 screens.
