Just would like to explain what the problem was. Sorry for being late.

If you have never launched OS 1.4 or above on your calculator, the boot2 version is 1.1.

There is a major bug with the 2.1 OS.
It cannot boot on a basic TI-Nspire with the 1.1 boot2.
(there is no problem with TI-Nspire CAS, and the boot2 code is the same on both basic and CAS TI-Nspire)

On a basic TI-Nspire with OS 2.1 and boot2 1.1, the calculator just freezes when the progress bar reaches 100%.


To fix the problem, you need to use the maintenance menu to remove the 2.1 OS.
Then, install and boot any OS 1.4 to 2.0.1.
This will upgrade the boot2 to 1.4.
Then, you can install and boot OS 2.1 without any problem.


TI is aware of the bug but has done nothing since july.
This is a big problem in France.
Nspire calculators aren't very popular and shops still sell old TI-Nspire with boot2 1.1.
The 1st time you connect that new calculator to the computer, TI-Nspire Computer Link automatically tells you to install OS 2.1...
And so, without doing anything unofficial, you're getting a new unusable calculator.

@critor: Wow, that's really shitty on TI's part. They really need to fix that.

Is Univers-TI ran by Texas Instruments? I wouldn't be surprised if it was ran by people working for them as well. Otherwise maybe they're affiliated with the Google group, kinda. However from what you describe, they seems worse than TI-Cares...

My posts about that bug on the official french Nspire  forum are just ignored, or are getting rude answers from the moderators (T3 teachers paid by TI), saying that this is not a bug and that I don't know what a bug is...

Your calculator is freezing permanently although you've done nothing unofficial... If it's not a bug, then I guess it's a feature?... :p

(they were trying to explain that it was the users fault, for buying outdated Nspire, and trying to install an OS not supported by the hardware... I guess they don't understand anything, like Ti-Cares...)

Why does it seems like everyone not affiliated with the TI community dislikes it? 3rd party programming has been a well recognized feature of computers for the past two decades. Plus, the only thing TI owns after purchase are the intellectual rights to the OS, which itself includes commands to execute programs. The purchase of the hardware includes the right to use the software for as long as the user wishes. Assembly programs using the hardware are well within the purchaser's rights.

Anyway, more on track, since TI is making the implied promise that their product will work with its purchase, they need to make sure that it does. Having the OS or TI-link detect the boot code version would probably be fairly simple to implement.
