Officially, no.
Unofficially, no[t yet].

Nope I think but there was recently a discussion about this and why this is not going to be made very public (legal reasons): http://ourl.ca/14645/275121;topicseen#new

From what I remember, in the news section of the site there was an update to OSLauncher that works most of the time, but I don't remember if it supports the CX yet. Of course we can't help directly on installing CAS on non-CAS, though, but hopefully such OSLauncher copy has instructions on how to actually get the application to work.

What do you mean? Of course keep in mind that the post you just quoted was posted way back in Early 2012 and back then there were worries about TI taking legal actions against OSLauncher if abused or even more anti-Ndless stuff.

Because it is against Omnimaga rules to discuss/teach how to load a CAS OS on a non-CAS Nspire model, regardless of if it's a CX or not. Granted, a tutorial might quickly explain how to load a different OS than the intended one on your calculator without specifically stating CAS on non-CAS, and that way it will get away from the rules even if it's pretty much the exact same thing, but if it goes in details and specifically explains how to turn your TI-Nspire into a TI-Nspire CAS, it will fall under the cheating on math tests category per the rules.

I don't think the whole piracy/theft thing is considered an issue here anymore since it was clarified over time that the OSes are all offered for free on TI website and we can do whatever we want with the hardware, in the same way as we can convert a TI-73 into a TI-83 Plus or a FX-9750GII into a FX-9860GII.

So, can I be pointed into the direction of some tutorial or will you guys help me solve my delema?  I bought the non CAS nspire CX for ACT and SAT and now that that's over with, I would like that OS on my non CAS calculator without spending another $140.

Sitting at school, playing with my teacher's CX and CX CAS software when I notice it wants to update my OS and asks if I want to install from a file. Went and downloaded a file for CAS, tried to install on my non-CAS. Alert window declares that they don't match. Is it possible there is a way to maybe decrypt the install file and then alter it so that it (the file) says it can be installed on a non-CAS calculator? Or vice versa so that the software that installs the OS believes that the calculator is one equipped with CAS? Just a thought, I'm not a major programmer or anything. Just a high school student with some computer and software knowledge that really wants to get CAS on my nSpire. (I know the file is encrypted because I opened it in notepad, filled almost completely with seemingly random ASCII characters)

If anyone has any ideas, I'd love to get this working again. Sorry to revive a dead thread, but this is everything I'm currently worried about when it comes to the nSpire calculators.

The conversion is possible:

Conversion of an TInspire CX to an TInspire CX CAS

Program-Sources Download …
• (1) software „nLaunch“ from
http://tiplanet.org/forum/archives_voir.php?id=12105
• (2) software „TNOC“ from
http://tiplanet.org/forum/archives_voir.php?id=1922&short=1
• (3) of TInspireCX CAS-update from
http://education.ti.com/download/...
actual version: TI-NspireCXCAS-3.2.3.1233.tcc
• (4) of TInspire Link software from
http://education.ti.com/de/deutschland/software/details/en/.../ti-nspire_computerlink
actual ver.: TI-Nspire_Computer_Link_3.2.0.123.exe

Creation of necessary update
run TNOC_en.exe
• (1) choose „Open“ and put in path to TInspireCX CAS-update
• (2) activate checkbox „Delete boot2“
• (3) execute „Process“
• (4) result: in folder of original TInspireCX CAS-update-file (e.g. TI-NspireCXCAS-3.2.3.1233.tcc) now exists a new file with „originalname“_b.tcc (e.g. TI-NspireCXCAS-3.2.3.1233_b.tcc).
• (5) this file has to be renamed to „phoenix.tns“

Connect TInspire with PC
• (1) connect handheld with PC
• (2) create folder „nLaunch“ on handheld using TI Link-software
• (3) in the lower panel (TI-Nspire file browser) right-click, New Folder, "nLaunch"
• (4) copy file „phoenix.tns“ to folder „nLaunch“ on handheld
• (5) if exist: copy files „nLaunch.tns“ and „preloader.tns“ from PC-folder „nLaunch“ to handheld-folder „nLaunch“

Reboot to delete OS
• (1) reboot handheld: press reset-button at backside of device and at same time buttons „doc“ + „enter“ + „EE“
• (2) release reset-button
• (3) release three buttons
• (4) handheld reboots and stops with selection 1-4.
• (5) choose button 2: „Delete operating system“
• (6) confirm with button 1
• (7) handheld deletes OS and stops, showing: „Press any key to restart“
• (8) execute restart („enter“), handheld stops, showing: „Operating System not found. Install OS now“

Installation of CAS
• (1) choose handheld in TInspire-Linksoftware at bottom right edge, (probably do „Aktualisieren“) and „Auswählen“:
• (2) choose „Extras“ at top, „Handheld-BS installieren“:
• (3) choose from PC-folder „nlaunch“ file „nLauch.tco“:
• (4) installation of new CAS-OS with „BS installieren“ and confirm „Ja“:
• (5) installation of new CAS-OS starts
• (6) PC shows „Fehler“: IGNORE ERROR MESSAGE !!!
• (7) The new CAS-operating system is installed correctly on TInspireCX (error message does not matter):

do setup
• do setup on handheld: choose „Language“ and „Size“ of writing

do CAS calculations
• do classical calculations, e.g.: factor, expand, integration
