If you are pushing in on the retainer with a tool and clamp, you are adding to the friction, it needs to only rotate without pushing in on the tool and retaining ring.
It was developed for the DS originally and specifically but has always worked on the NDS of cup and cone BB's as well.
If we emailed about the method in the past, I would like to see pics of what's going on. PM if need be.

this is what an ungreased BB cup looks like!!
