Nope, I'm sure these screws are fucked up and stuck there.I agree with all of the below suggestions and will add one more; Before adding the oil TIGHTEN the screws as much as possible without breaking them. This will open the other surface of the threads to the oil. I now always tighten screws before trying to loosen them. Quite often helps. Also: EXACTLY really means 100% exactly! Take the lens with you when you shop for screwdrivers. I own about 50 phillips that are ALMOST exactly the same size.

I screwed loose the back section of the lens and got a little space to look around.
It seemes there's a small spring beneath the thingy that closes down the diaphragm. A part is missing from that spring.
Now, i figured, hell, even if i can remove the bayonette and open everything, i still dont have a spring like that. Where the hell am i supposed to find a teeny little spring that fits exactly?
I give up for now, i hope it's atleast a bit good full open.
