nLaunch is an alternative OS launcher alternative TI-Nspire, which is injected in the boot2 3.1.0.16.

It bypasses all protections and install:

• development OS
• old OS with a version number less than the minimum installable OS version
• modified OS
• third party OS like Linux
• CAS OS on the non-CAS TI-Nspire and non-CAS OS on the TI-Nspire CAS

This last point has recently been a problem for Portuguese exams prohibiting the use of a CAS engine.

As a consequence, we were not surprised to discover in a previous news a new 3.2.4.1237 OS on the latest manufactured TI-Nspire CX calculators.
Indeed this OS:

• updates the boot2 to a 3.2.4.7 version which fixes the flaw used by Nlaunch
• increases the minimum installabl OS version to 3.2.4.1200, thus preventing any return to an Ndlessable OS, which would have allowed you to reflash the Boot2

In an official document, Texas Instruments has communicated with Portuguese teachers:

This paper discusses several points:

• it explains what Nlaunch is
• it explains how to check if a TI-Nspire uses the CAS engine or not thanks to the model name displayed on the 'about' screen accessible via
  
  
• it explains how to uninstall Nlaunch, by sending two successive TI-Nspire OS
• it says that since December 2012, OS 3.2.4 has fixed the problem - which is great as Nlaunch was on released only on January 1st, 2013! Did TI anticipate the problem? :O
  
• it announces OS 3.6 but not for this summer summer anymore: for October 2013
• it mentions a new feature of OS 3.6 which will help to detect cheaters more easily on exams where the use of the CAS engine is prohibited, as this information is now available directly on the home screen!

This goes far beyond the simple detection Nlaunch because there it will also detect adepts of the "case switching" who put the TI-Nspire CAS hardware in the TI-Nspire non-CAS case!

lol, a cas indication on the screen >.<
But they can't prevent that stuff on the old nspires that are already sold

OSLauncher.tns ftw

It works perfectly in my Nspire classic and i don't need 3.2. Even if I did need 3.2 I could use oslauncher as well to start one OS at a time (3.2 and CAS).

Not in Portugal unfortunately

Lol install linux, attach a wifi dongle and ask someone to do the exam for you

IMHO fighting cheaters and making sure they can be caught easier is a good move, but it sucks that TI constantly punishes everyone who don't want to cheat and instead want to succeed in school. Those students spent $150 on a tool they use legitimately to help them learn and they should be able to do whatever legal thing they want with it, now that they own it. Once again, everyone's rights are removed for the action of a few lazy students (who cheat in order to pass their exams) and lazy school administrations (who don't want to bother checking people's calc content prior starting the exam).

Not sure, but probably someone who absolutely despise TI who was upset that Critor's post didn't bash TI really hard like in the OS 2.1 days and he decided to rate his post based on his opinion of TI rather than content. I rated it back up since I don't see why it should be downrated.

As for the move, I just hope that this doesn't permanently prevent any downgrade exploits and that the days of Linucx aren't counted.
