No, a broken-up helmet does not provide any protection to the wearer.
It has failed.

Before it broke up?

Airbags that explode on use leaving small pieces of cotton lying on
the floor of your car didn't work. To work, the bag has to remain
intact, just like a helmet.

No, it hasn't failed. Energy was used in breaking the helmet instead of
energy transferring to the head. Granted, not all the energy was used but
some was. Too rigid a structure will transfer rather than dissipate energy.
A lot like running into a brick wall unprotected or tying a balloon on your
chest and hitting the wall. The balloon will burst (if you hit hard enough)
but will deform and slow you before you hit the wall. The balloon hasn't
failed simply because it was destroyed in the process.
