nLaunch CX...

[rafael rodrigues]

I couldn't install the OS that came with the rar. Besides, I didn't really understand how to put the CAS OS on the Nspire CX. If anyone could help me, it would be great. For the time being I installed native OS that came with the product since I could'nt figure out the needless one...HELP

j'ai le même problème .Est ce que quelqu'un a la solution ?

As-tu déja l'os 3.1 et ndless ?

[Lionel Debroux]

nLaunch CX n'a pas directement besoin de Ndless, ni même de l'OS 3.1 d'ailleurs. Tout ce dont il a besoin directement, c'est du boot2 3.10.16 quand il est appliqué à une CX, et du boot2 1.4.1571 quand il est appliqué à une Clickpad / Touchpad.

Pour disposer du boot2 1.4.1571 sur les Clickpad / Touchpad qui ont déjà un boot2 3.1.131, il peut effectivement être plus facile d'utiliser l'OS 3.1 et Ndless 3.1 pour reflasher ce boot2, plutôt que d'utiliser un adaptateur USB / RS232 TTL.

je parlais de l'os 3.1 et ndless, parce qu'en fait je me suis dit (peut peut être un peu trop vite) que son but était de mettre l'os 3.1, ndless et l'os 3.2. J'ai peut être tort.

Hi

Before all i want to thanks all the work that has been done in here.

However i have experienced some troubles to change the OS of my Nspire cx non-cas.
As told on the readme file i'm stuck at the step 10.

"10)reboot, transfer nlaunch.tco/tcc to your calculator (an error will certainly
be shown on the computer, check if it is ok on your calculator)
- /!\ the initial exploit can fail. If the progress bar is stuck at 60% and
nothing is shown (you should briefly see "YZ") at the top left of the
screen, reset and send nlaunch.tco/tcc again.
- /!\ getting to the OS the first time can be fairly long (max 3 min); the
progression bar can be quite unstable. If the bar did not move at all
during 3 minutes, consider the boot as a failure
- NOTE: unplugging the USB cable "at the right time", i.e. after sending
the TNO/TNC and shortly after the bar has reached 60% again, may increase
the reliability of the installation procedure. Likewise, the second
generation of Ndless (1.7/2.0) worked better when USB was unplugged."

As i try to transfer those files (nlaunch.tco/tcc) to the nspire cx i get an error message like this and i can't get over it.




Even if i try to restore any other OS i get this message and the nspire is stuck at this point without any OS.





I think i did all the steps correctly as no error message was displayed.

Can anyone help me with this problem? I have a great urgency to solve this problem as i need it everyday and an expensive paperweight is no useful to me.

Many thanks

Hi.

Did you try both files?
nlaunch.tco and nlaunch.tcc

[Levak]

What was the OS installed before your tried any manipulation ?

[don_pepperoni]

Hi critor

yes. I tried both files.
The error to the tcc file is this:




and to the tco file is this:




Hi levak

The OS was the 3.2.3.1233

[critor]

Thank you for the captures.

It could mean that you don't have Boot2 3.1.


What kind of operating system are you using on your computer?
