I had a lot of trouble with this part as well...It took me a bit, but ended up getting it.
If you pull on the 1st one, it will reset 2
If you pull on the 2nd one, it will reset 1 & 3
If you pull on the 3rd one, it will reset 2 & 4
If you pull on the 4th one, it will reset 3
I ended up getting the two levers on the left to be up, and the two on the right to stay down. After that, I pulled on the first lever (one farthest to the left) and it opened 2 doors, one of which is the small hole you passed along the wall on the way to this room.
Hope it helps!
Thanks to Gackt for the awesome sig!
