Something is wrong but we don't know what is taht yet. Make sure there are no short circuits. The fact that the NEF burned out at 3.3 is strange. Also check that the CSN and CE pins in the code are the sam taht you have soldered, usually pins 9 and 10. Then, ty using short wires for thr receiver betwenn Arduino and NRF24. SPI communication might have a lot of noise with long wires!
