That's why we should not force the installation of the OS we want to lauch, but run it over another Ndlessed OS.
When you restart the calc, you'll just have to:
- Ndless the original OS again
- relaunch your "special" OS

Thank you for the news.
Just for information, Boot2Launcher has been developped by Bsl.

 You can buy the sildecase separately for 3$ in North America. I don't think I could sell it cheaper (customs, taxes...).

After many requests from angry users to TI-France, it has been officially annonced today that Nspire CX calculators sold in France will include the slidecase.

Does this mean that the ones sold in the United States will also come with a slidecase?
I don't think so... "France" is clearly mentionned in TI's post.

According to the video that was posted, RunOS was launching the OS directly.
But, you'd have to get a decrypted OS image first, which is not easy at all for the end user.
So it might be usefull to use a modified boot2 in order to launch the OS from a simple tnc/tno file.

I wonder if Martin actually has ROM dumps?
Hello,
I have ROM dump of the cfx9850G from 1997. This model has physically 32 KB RAM (not 128 KB as written above).
I tried many examinations of ROM to enable asm on original device and I did nearly proof, that this is not possible (on the old models).
Does some kind of emulato exist for those models? What's the CPU?

Be careful with boot2launcher .
If you launch a developer boot2 on a production OS (or vice versa)it will delete that OS.
Which is normal as the production and developer keys are different. (but shouldn't be a problem, as the developer boot2 images haven't been shared publicly)By the way, thank you for you great work Bsl.  Maybe with a modified boot2, we could also run production OSes on Ndlessed basic & CAS TI-Nspire prototypes.

Yes, if we use a modified boot2 which could load any OS, it could also load a modified OS.

Just released! Non, not RunOS yet... But the very similar Boot2Launcher program by Bsl! You can launch any uncompressed boot2 image: - a different image (newer or older) from the one flashed in your NAND ROM - a prototype image on a production TI-Nspire - a production image an a prototype TI-Nspire - ... Useless, you think?... But the boot2 does care with everything related to launching (or not launching) the OS. Guess what could be done by launching a slightly modified boot2 image... Guess what's next... Read/watch more (in french): http://ti.bank.free.fr/index.php?mod=news&ac=commentaires&id=1026

Anyway RunOS was not released to avoid giving TI good reasons (such as being able to run the CAS OS on a non-CAS TI-Nspire) for enabling the downgrade protection. Which they did anyway, starting from OS 2.0.0 on TouchPad models, and from OS 2.1.0 on all models...

Trying to load an nspire CAS image on a regular nspire just locked it up(both were OS 2.1). Does it work the other way around?
It depends upon the way you're trying to load the OS. If you're using the original boot2, of course it's checking the model type and won't load a CAS OS on a basic Nspire.

Overwriting is not a good idea, untill we can flash modified boot1/boot2.
But launching an OS without installing it, assuming it is "similar enough" with the installed OS might be the way.
That's why my example was launching the 1.7 basic OS from an Ndlessed 1.7 CAS OS.

Nice. I wish somehow it was possible to just launch an Ndless program that overwrites the entire OS content and bypass the protections...
You can overwrite and might be able to run it by the same time... But you'll have problems during the next reboot.
