Enter the room with a shinecharge. Run and jump off the ledge. Fire a shot mid-air and activate the shinespark wind-up. Take a hit from the the Bull (if power is on). Wait until the shot is at a specific position before sparking. Sparking too late will cause the shot to despawn before reaching the door. Sparking too early will cause Samus to bonk the door as it will not yet be open. A beam shot, Missile, or Super can be used.
