nRF24L01+ module fried?
Assuming you have triple checked all your wiring before posting this question you should add a small capacitor between Vcc and GND near the nRF24: anything between 10uF and 100uF will do.

Rationale: these devices draw quite a decent amount of current when bootstrapping and transmitting and if they don't receive enough juice they just reset themselves showing those all zeroes settings.

They are pretty robust devices, not that easy to fry.
