Since there are many Ndless help/support threads popping up on Omnimaga, it might be best to consolidate all of the major questions/answers into one thread, which are listed below:

1. Where can I get a copy of OS 1.1?

Sadly, we cannot distribute copies of the TI-Nspire Operating Systems.  OS 1.1 is out there on the internet.  Just look around, you will eventually find it.

2. When will Ndless be released for an operating system other than 1.1?

Right now, official Ndless releases are only compatible with OS 1.1.  There are beta versions of Ndless that work on OS 1.4 and OS 1.7, but these versions are intended for developers and are not completely stable.  If you want, you can download the latest source code for Ndless here. (guest/guest to log in).  Please note that you must build this version yourself, as it is intended for developers and is not stable.

3. Can I install OS 1.1 on my touchpad Nspire?

Technically, you can install OS 1.1 on any Nspire, but OS 1.1 is not compatible with the touchpad keypad.  Therefore, OS 1.1 will not work if you have the touchpad keypad in the Nspire.  You will get an infinite reboot if you use the touchpad with any OS lower than 2.0.  See the answer to question 4 if you have installed OS 1.1 but you do not have a touchpad.

4. I installed OS 1.1 on my calc, but now it is infinitely rebooting!!!?

If you are using the touchpad keypad, this is caused because OS 1.1 is not compatible with the touchpad keypad.  If you get an infinite reboot, you should delete the OS like so:

Hold down the following keys until a menu pops up:

Clickpad: Home, enter, p, on
Topuchpad: Doc, ee, enter, on

Then, select option 2 (Delete Operating System)

Finally, resend your desired OS to your Nspire.

5. I tried installing Ndless on OS 1.1 using Ndless 1.1.1, but it did not work!?

This can be caused by a number of factors.  Most commonly, this is caused because Ndless is not completely compatible with Computer Link Software version 1.4.  Try downgrading to version 1.3, which can be downloaded here.

6. I installed OS 1.1 and Ndless 1.1.1, but now when I turn my calculator on, the screen does not turn on!

This is not caused by Ndless, but by a hardware change by TI that affects all TI-Nsprires running OS 1.1 made after 2007.  There is no known fix to this problem, but a workaround would be to have a Ndless document to reset the calc every time you turn it on, making the screen turn back on.  You can download a reset document, by calc84mainiac, here

7. I tried installing Ndless 1.7 on my calc, but it froze and random pixels lit at the top!

With the latest version of Ndless 1.7 (SVN Update 315 or later), this is not too much of a problem anymore.  Update to this version if using a older version.  Most of the time, Ndless will now automatically reset your calculator if the instillation fails.

8. I want to write programs for the TI-Nspire.  Where can I get the information I need to get started?

First, follow the tutorial in the Ndless ReadMe file in order to set up an Ndless development.  After you have the development environment set up, visit Hackspire, where you will find many resources documenting almost everything known about the Nspire!



If you have any additional questions or problems with Ndless, feel free to post them below and we will try to answer them promptly and add them to this original post.  Different issues can come up at any time, so don't feel bad about posting if your question is not in this post!

Excellent apcalc!

DJ Omnimaga: my personal attitude on Ndless 1.7 is to help anyone who can make it grow and become more stable with ideas, tests, fixes, ... I am least inclined to help end-users to play NES/GB games with Ndless 1.7, who could complain of its instability.
I think any FAQ in this direction would be useful.

Aren't those links temporary, though? It seems like a session ID or something. I think he will need to go all the way from TI homepage and nagivate through the maze of links.

Yeah same, now. I think it has to do with how they changed their site and requires you to login, now. I guess the only thing that can be done is posting the full navigation path.

I think this is as close as we can get to a direct link:

http://education.ti.com/educationportal/sites/US/productDetail/us_nspire_keypads.html

Where exactly are the binaries, codes or files, and what do I do with them once they are acquired . With the lack of knowledge of nspireOS coding, I don't even know what language it IS in. Do I require any applications on my PC (such as activeperl) to compile it? I have, without intelligent wording, no idea how to program directly into NspireOS at all, not really knowing what Ndless "is" (a Ti-BASIC application?) at all in the first place . Is it already "halfway" compiled, compared to something such as S60 (being the most numerous and nonrestrictive mobile OS) and its .sis signing. Is there even an installer for ANY ndless distribution at all? At the most basic level, what exactly IS this???

please help, i bricked my ti nspire with ndless 1.7, now it keeps resetting itself and i held doc, enter, EE, and then held on or clicked on, and it won't give me that menu to reset, please reply

i fixed it thank you, i noticed i had to hold the keys beforehand i press the on. some other website keeps telling me to hold it when its loading
