JustinDM's out of bounds video: youtu.be/3J3k2faGQuo
Normally when you skip Metroid Prime Exo intro cutscene, a check to prevent you from moving before Subchamber One finishes loading is executed, so when it's done loading you can move again and you can see the room from Phazon Infusion Chamber. HOWEVER, if the room is done loading before triggering the cutscene, that check is disabled, and there is nothing that activates it again.... so we can transition to Crater Tunnel B to unload Subchamber One, then enter PIC again and trigger the cutscene.
Since that check is now disabled, the cutscene will end immediately without waiting for Subchamber One to finish loading, so we can abuse that to quickly go out of bounds through the hole that would normally lead to that room. I use load delay to make the room take longer to load, but it should be possible to do it without, though much more harder.
What you need to do afterwards is use the corner of Subchamber One's collision box to aether jump up, then go back to Phazon Infusion Chamber to find a standable spot to jump off, and get more height and avoid the cutscene trigger.
Then proceed with the wallcrawl as normal, except that from left side.
