Okay, so dont shoot the messenger here. this is only theory here and therefor, is not breaking any rules
So, while messing with the emulator, i needed to pull my boot1 and 2 i do that and get the cx normal os booting fine.. But i want more! so i took the cas os file and booted it like the normal version, with the same boot 1 and two. Guess what, it worked! Everything works great in the cas emulator as well. So, what im thinking is if TNOC can delete files from the updator why cant it add files? sure we need help from others, but the thing is couldnt we just take out our Ti-Nspire.img and replace it with the CAS one? Leave the certificates and you should be good, and it should boot. You can easily test the theory in the emulator before trying it on a calculator, but the idea makes good sense to me.
