So here is what I don't want to end up doing:

Hi,


Some TI-Planet content is available in both english and french.
It should default to english for guests when their computer language is not french.

Once regestired, you can set your preferred language in your user profile.

Anyway, you may ask your question in both french and english - most of us speak english too over there



If you did update your TI-Nspire HW-E to 3.6, then your Boot2 was also updated to 3.2.4.

To freely read PDF you need Ndless which requires OS 3.1
But OS 3.6 forbids you to install OS 3.1.
Thus you need Nlaunch, which makes Boot2 ignore the minimal installable OS version set in memory.
But Nlaunch only works with Boot2 3.1.

You then need to reflash Boot2 3.1.
This requires an external hardware: an USB/TTL interface:


By putting the TI-Nspire in Boot2 receive mode (Doc+Enter+2 while rebooting) and connecting ground, Tx and Rx to three contacts on the TI-Nspire bottom J01/Dock connector, you can reflash Boot2 3.1 with the Hyperterminal software coming with Windows up to Vista.


After this is done you can litterally do everything you want with your calculator, and we have comprehensive tutorials in both french and english for each step

So here's what I'm working with: ti-nspire cx cas, Version 3.2.0.1212, Boot1 3.0.0.99, Boot2 3.1.0.16

After drinking from this forum's infinite wisdom, I found that I dodged a bullet not updating any higher.
Now I want to keep avoiding that bullet and get ndlessly goodness, but i need some guidance.

So I have the right 3.1 update file (assuming TI didn't to some malicious switching).
I never even installed computer link before, so how does that work with installing the OS? Which version should I use?

Do I need to TNOC anything? (not that I know how) 

Special request, anyone know how to get the student software 3.1 version?

Edit: google chrome translator is awesome

The site i linked you to in your "introduce yourself" had instructions on installing ndless

Thanks guys, but I'm not having trouble installing ndless, I'm not even at that step yet. I want to downgrade with out messing up, so ideally i'm looking for someone who has done it before.

can anyone link me to a 3.1 version of the student software and computer link software? I couldn't find it on TI - planet.

Do I need to TNOC the 3.1 update file?

Thanks! just what I wanted to know!

about to give it a try

IT WORKED! without a single problem at all!

Thanks everyone, I can't express how happy I am after all the reading I've done last night.
Your response made me feel a lot better about this.

Excited to try a bunch of stuff but first, a nap

Good to hear that it went fine without much hassle. Now just be careful with some programs like Nover (read the readme carefully) and make sure you run the latest Ndless version, to reduce risks of having to reformat after an Ndless program crash. When I used my TI-Nspire on a regular basis to play games, I had to reformat it at least once a month.

I don't remember the exact key combination to access the maintenance menu, but when the calc goes bad (eg it fails to boot the OS) sometimes we have to go there to remove the OS and reset all data. Then we re-install OS 3.1, Ndless and all our programs. It is usually pretty rare, especially with Ndless 3.1, but it can happen.

for maintenance menu, press doc, enter and ee while holding these, press reset on the back

You can also hold down these keys while the calculator reboots (it might be hard to press all of those and reset at once )
