Well they got nuclear detonation, yes. They never quite got "miniaturized nuke," though, as in "one you could put on an ICBM." So presumably they were working on that crucial development alongside their rocket tests.

I am skeptical that they never got that working - NK is sort of known for having connections to all kinds of shady people and 'miniaturized nuke' theory has been around for, well, a while so it's possible someone told them how for a lotta money or other stuff. But again, it's possible. The lack of real knowledge on our end (you and me) makes it really hard to estimate what they do and don't know, what is a facade and what isn't, etcetera. NK has surprised us in the past before - I would not be surprised in the slightest if they had an ace up their sleeve.
