Hello, I was reading how to install ndless 4.2 in TI-planet.....and I have a question....well I have a nspire cx non cas with serial P...B

I upgraded from to 3.0 to 4.2.0.532...but now I really need the cas version,also I already installed ndless 4.2.

.....is there any way to transformer my cx non cas to cx cas using that ndless??
