That seems suspicious, unless hardware J had some defect and they are releasing an update quick >.<.

A new hardware revision every few months seems quite normal for the CX: after about 3 years we're already at revision K.

Why does TI even hate Ndless so much anyways?  Doesn't that make more people buy Nspires and earn them more money?

Well apparently it's the common thing now that we can only be sad about : none of the recent new big calcs (HP Prime, Casio fx-CP400) offer native coding capabilities. The Nspires were just a bit ahead of their time, I guess ; maybe since TI is the major seller in the US.
It's mainly because the exam institutions require them to lock down the device (or at least make it very safe), and well, TI/HP/Casio just go the hard way by not providing native access on top of PTT.
Especially when we're talking about their flagship product : they certainly don't want troubles with the exam institutions arguing wethere the platform is very secure or not... (and not only that, but they want to keep their main customers (teachers/schools) in trust, saying that protections are effective etc.

We can see the "quick" reaction after nlaunch, and we continue to witness its extent even these days (OS 3.2.4 with now boot2, new HW revisions blocking exploits upstream (since boot2 etc. can't be downgraded) )


And also, I wouldn't think of native programming capability as an sole argument of selling (like "I want to program in ASM so I'll buy a 84+"), but more of a bonus to a choice when buying (like "I'd prefer buying this calc over this one because there is also native coding capabilities"). And since TI customers (more than 99.99%) are not native coders, they (TI) strictly don't care about it.



Edit : by "exam institutions" I mean "standardized testing regulation authorities", thanks Lionel

Sadly, the fact is that standardized testing regulation authorities in multiple important countries

IMO as long as PTT exists and noone tries to hack it they are OK with Ndless (unless someone tries to bring a non-CAS calc with nLaunch to have a CAS OS).

PTT hacking tools released on Omnimaga were immediately moderated.
And I'm sure TI knows about that. So if that's what we get as a thanks...

As far as I know, PTT hacks are currently only available on cncalc.org for registered users with several posts (else, you can't download). And of course, only if you manage to find them in chinese...


Nlaunch purpose was not to bring CAS on non-CAS, but to have Linux and to be able to use Ndless together with OS 3.2. We didn't encourage other uses and nor did the ReadMe.
Who's responsible for fixing Ndless flaws in OS 3.2 ?...
If Ndless could have been easily installed on OS 3.2, would Nlaunch even have existed?...

By permanently fighting against Ndless, they just make people release more and more important hacks.
So, either HW-J/K + OS 3.2.4/3.6 is perfectly secure and TI has allready won the war they've just started...
Either the next hack is going to be a big nightmare for them.

So you want the next exploit to be released only as a binary?


Ndless sources have been useful for user contributions, and there has been many of them.

Nlaunch sources were useful in order for us to maintain and slightly improve the tool - remember that the "Nlaunch team" and/or "Nlaunch guy" never came back.

If some of us are able to dissassemble the huge OS/Boot2, TI guys should perfectly be able to disassemble our small tools.
