nLaunch: Now for CX!
« on: April 01, 2013, 04:41:06 am »
This morning (for us in Europe), an anonymous person posted what he pretends to be a nLaunch for CX: http://tiplanet.org/forum/viewtopic.php?f=20&t=11483 and http://www.cemetech.net/forum/viewtopic.php?t=8992

Quote from: nlcxguy
Hi,

I'd first like to thanks the nLaunch team for their awesome tool!
After weeks and weeks of hard work, I am proud to present you nLaunch CX :D

Please spread the word so people do not upgrade their calculator to the next OS version without using TNOC!!

nLaunch CX features the same functionalities as nLaunch, on Clickpad, Touchpad and CX Nspire:
* launching Linux (modified nspire-linux-loader2)
* optionally installing Ndless 3.1 on OS 3.1 (modified Ndless loader)
* installing and launching any OS

Hope it will work fine for all of you!

nLaunch Guy

Given today's date, skepticism is warranted. But my own testing shows that he's not merely pretending that what he uploaded is nLaunch for CX (!!) - it actually works. Like nLaunch, it's based on arbitrary code execution in the boot2... and, BTW, the contents of the .tco and .tcc shows that it's the same kind of vulnerability, in the same group of functions as on the Clickpad / Touchpad.
I tested a single thing (before having breakfast...), but my CX CAS Nspire is now single-booting Linux, without going through TI's OS. :)

nlcx is making the same recommandation as we've been making for years: use TNOC before upgrading one's own Nspires' OS !

We'll keep you informed about testing and new development about nLaunch CX, and we warmly thank "nLaunch CX guy".

It's another wonderful day for the Nspire community :)
We thought it was impossible, but somebody did it...

You got to be kidding me is what I first thought, but it's true? o_o This is a nice discovery :D

If I've not posted yet, it's because I'm testing. ;)

So we will soon be able to have the dual boot Linux/TIOS on CXes, like on Classic models ?
I own: 83+ ; 84+SE ; 76.fr ; CX CAS ; Prizm ; 84+CSE
Sorry if I answer with something that seems unrelated, English is not my primary language and I might not have understood well. Sorry if I make English mistakes too.

There is no way to have a dual boot Linux/TIOS on Classic models right now. That would require some changes in nLaunch, and nobody made them (yet?).

nLaunch CX is real.

Here is my first news about launching a CX CAS OS on a non-CAS TI-Nspire CX:

If I do this, will I have to delete everything off my calculator?

No - just the OS.
