To do the process so far i used mac os X. However the TNOC's step was made on Windows 7.

It would be nice to check the Boot2 version using the TI-Nspire Computer Link.

Under Windows, it's in the top menu: Tools -> Informations on the handheld.

Apparently, that menu seems to be missing or hidden on the Mac version.

I tried that menu on Mac OS X and worked.

Thank you very much.

Ok, bad news: you have Boot2 3.2.4.7 and nLaunch needs Boot2 3.1.0.16.
That's why nlaunch.tcc and tlaunch.tco weren't working.

In the current state of your calculator, it's impossible te reprogram the Boot2 through a software.
You need some specific hardware: an USB/TTL interface (often mentionned as RS232) to connect to the bottom connector of the TI-Nspire.
There is no other way to go back to an older Boot2 version.

For the moment, to repair the calculator you can install OS 3.2.4.

And to install that OS is like a normal OS, through the ti-nspire computer link?

But with the OS 3.2.4 i can't start again all the process without plug the calculator to the RS232 right?

You can't complete the process without RS232 anyway, because your calculator already has Boot2 3.2.4.

In the current state of your calculator, you won't loose anything more when installing OS 3.2.4
