RE4 - Found a Few Glitches on PS4

Found a new glitch tonight thanks to a viewer!

Glitches used:
Mine cart skip (30 fps version)
Boulder Skip (drop-down)
Dos El Gigante fight skip
Striker double speed (of course)

New glitches discovered:
Rising Robot Salazar palm airwalk (To do it: Jump onto the Salazar robot's palm about a fraction of a second after shooting the switch on its stomach. If done correctly, you'll be floating in the air and can airwalk everywhere, even out of bounds).

Experiments/Progress:
The right door in the water room can be opened but it acts as if it's closed even when it's open, and an invisible wall is present. To do this glitch: Have Ashley follow you, run all the way against the door while facing it, aim down sights to get Ashley to hide behind you, turn around while aiming to get Ashley pushed into the door, the door will open (you can hear it), tell Ashley to wait, and then turn around. The door will be open but you can't get into it. Grenades can be thrown into the room though.
There is no feasible way to skip the Chimera door trigger. Grenade jumps don't get Leon high enough to go over the trigger point; and the trigger point seems to run from the left wall to the right wall, from floor to ceiling, just past the first tile between the last two columns.
There is no way to skip past the two fire breathing horse sculptures. There's an invisible wall just inside the fire, and grenade jumping doesn't work.

Future ideas:
Maybe tossing a grenade and then immediately shooting an RPG at the ground might allow for a sort of "double grenade jump", where the rocket hits Leon and then the grenade goes off to push him further. -- Watch live at   / i_am_underscore
