I just recently bought a TI-Nspire CX (with OS v4.4 on it) and downloaded the student software onto my computer. When I connected the calculator to my laptop, the software said to update the CX OS to 4.5, which I did. Then, I found out that Ndless only works on calculators up to 4.4. Is there any possible method of downgrading my CX OS from 4.5 to 4.4 so I can download Ndless?
Downgrade TI-Nspire CX 4.5 to 4.4 for Ndless?
Summary:
How can I downgrade TI-Nspire CX OS ver. 4.5 to 4.4 so I can use Ndless?
