hi
i have ti nspire clickpad version 3.2 and i'm wondering how to upgrade it to cas version.
i searched in the net but it seems that the ndless is not yet comptatible with the last ti nspire firmware.can someone please help me to upgrade my graphing calc?
thank you in advance.
-
it is not possible iirc unless you do some hardware-modding.
-
Thank you for reply
can you tell me the reason why ,because i saw a tutorial on tiplanet.org how to do it but were talking about an earlier version of nspire.
thank you for giving me some clarification
-
Well, the thing is that the CAS models are more expensive even thought they don't really have different hardware. TI prevents with a tiny hardware-change the validation of CAS OS's on non-CAS models, because they don't want to sell their hard work making the operation system for free.
The thing of modding a non-CAS calculator to a CAS calculator is so far only possible with nspire prototypes.
But, I must say, I'm not an expert in this aria, I don't even have a nspire, my knownledge is only from reading through forum posts.
-
Anything is possible with lots of time, effort and sometimes lots of money. It's probably not worth trying to get the CAS OS to run on a non CAS since I'm sure it will take a very long time and effort. If you want you can try though.

No problem: just downgrade your TI-Nspire by installing OS 3.1.
Then you can use Ndless and OSlauncher :)

That was some time ago (ndless 2.0 IIRC). There was a program called OSLauncher that allowed users to hotlaunch an OS different from the one they were running, thus being able to run a CAS on a NON-CAS model. I believe there is a 3.1 version of it somewhere , but that fails to launch a CAS OS (?)
Anyway, you will need ndless to perform this action, therefore you'd need OS 3.1. So in the case of OS 3.2 there is no other option than to either downgrade back to 3.1 and try it or wait for ndless 3.2.
[edit] pressed the post button too late :P
-
OSlauncher for OS/Ndless 3.1 can launch:
- non-CX OS 3.0.1
- non-CX OS 3.0.2
OS can be CAS or non-CAS.
OSlauncher for OS/Ndless 3.1 cannot launch:
- CX OSes
- 3.1.0 and newer OSes
Nobody seems to have been interested into understanding why, nor into fixing that.

salut critor
donc si je reviens au systeme 3.1 ou 3.01 serais je capable d'effectuer la modification de mon nspire a la version cas?
pourriez vous m'eclairer un peu la situtation svp, car je suis nouveau dans ce domaine.
merci d'avance.

English spoken in this section, even if DJ_O and Juju live in Québec as well, and critor and myself (among others) are French :)
Indeed, if you go back to the 3.1.0 OS, you may be able to launch 3.0.1 OS. OSLauncher works well on some calculators, but it's extremely unreliable on others.

thank you for your help dude.

Heya and welcome here :D. Also wow I didn't remember there was an OS 3.0.1 compatible OSLauncher. I thought it stopped at 2.0 or something (and Ndless 2.1).
I think it stopped being maintained much because some people wanted to use it only to cheat on tests (which almost every calc community heavily discourage) and concerns about the legality of it.
-
Nope, there has always been absolutely zero concern about the legality of OSLauncher. It's completely legal, as part of the right to run the software we see fit on the platforms we own. That's precisely why OSLauncher was released alongside DummyOS.
If running arbitrary OS on their calculators were illegal, they'd have sued whoever attempted to do that over more than 10 years of TI-Z80 and TI-68k calculators. TI sent illegal DMCA takedown notices for the perfectly legal distribution of RSA signing/validation keys (and got dutifully slapped for their incompetence and abuse of the legal system), so what exactly would they have done for things that are actually illegal ? ;)
Extremely few people are interested in making an OS for the Nspire series; nowadays, there's an initial Linux port, but OSLauncher and DummyOS predate it by about a year and a half.
-
Oh yeah right. I was more curious about the part involving running the OS of a calc that is more expensive on a cheaper model that is almost identical hardware-wise but runs a different OS. But again it's our hardware and TI offers those OSes for download for free, so it was kinda their responsibility to add some protection so that the CAS OSes in particular can't run on non-CAS models or vice-versa.
-
Indeed, but even then, such protections can be rendered ineffective in a number of circumstances :)
-
Indeed.
(By the way this is such an evolution of the days, where in large stores where employees couldn't pay attention to merchandise properly, people would open packages of two items and swap them to get one for cheaper, and the cashier simply thought someone else had opened the package and it was the last item in stock. :P)
-
Really? Shouldn't you become just a little suspicious when someone wants to buy something that has already been opened?

Probably, though I've noticed in a lot of badly-maintained stores that the last few items in stock do tend to get abused while they're on the shelf, so the cashier might not even notice :/ It's definitely illegal.
Should also say that we do not condone cheating on tests, as DJ_O mentioned earlier.
-
Actually nevermind what I said. I totally forgot that TI calc packages requires a chainsaw to be opened (although they're much easier to open than they used to be in 2001-02).
I did see stuff like that happen in some stores, though. Zellers stores are particularly bad about that. When I went to their printing furnitures section about 70% of the ink cartridges packages either had holes in them or were opened, and some other items are in terrible condition (especially books). And in other stores, I remember buying an item that was opened and it was one of the last in stock so I just said to the cashier that there were no other left when she asked.
