Can you still extract the crank using the self extractor?
If yes, then just don't fool with it.
If, when you now try to extract the crank using the self extractor, it pulls out, then you are f'd.
If the self extractor pulls out - without extracting the crank - then you could try screwing in the crank extractor tool and see if there are enough threads left to seat the tool firmly and pull the crank.
Otherwise, you are looking at a new crank ;-((( Live and learn. I hope you messed up the NDS crank. That's a much cheaper booboo.
