Premièrement, je suis chinois, et c'est DouBao AI qui traduit le chinois en français.
J'ai acheté avec joie un USB2TTL, et je veux dégrader mon TI-nspire CX version 4.5.5, version matérielle Y, qui semble perdu(e) (pour installer ndless). Je voulais utiliser nLoader de critor pour dégrader mon CX, mais en voyant les instructions d'installation, j'ai été choqué(e), car le processus nécessite également ndless (même mon ami Lize dit que ma calculatrice ne peut pas être dégradée).
我开开心心地买到了USB2TTL，想给我那个已经没有希望了的版本为4.5.5的硬件版本Y的TI-nspire CX降级(用以安装ndless)。我想用critor的nLoader给我的CX降级，但是我看到安装办法的时候我人傻了，因为安装过程还需要ndless(我的朋友Lize都说我的计算器降不了级)

@critor

Hello.

I am sorry, but without an Ndless version update compatible with version 4.5.5, there is no way to downgrade your calculator.

NOOOOOOOOOOOO!!!!!!!!!!!!!!! MY NSPIRE CX!!!!! (emm.......But I can play my Nspire Clickpad )
Quote the README of nLoader(https://raw.githubusercontent.com/parro ... README.txt):If you are on OS 4.5.5 or newer, you can downgrade your OS or install Ndless by creating an nLoader image file directly using make_for_emulator.sh, then flashing it with a 3.3V USB to serial adapter: viewtopic.php?p=219587#p219587
But I don't konw what the meaning is.

Thank you for your reply, maybe you're right, my apologies, I never had to try this way.

In theory it could work :

1. create an nLoader image file
2. flash it in your Boot2 partition by securely connecting your USB adapter to the TI-Nspire CX dock connector
3. and then install an nLoader compatible OS version

It's covered by the nLoader installation how-to :

But you'll need Ndless (on another calculator or on emulator) for this specific step.


What's your current TI-Nspire CX model ? CAS or non-CAS ?

I don't have another one and the model of my calculator is non-CAS.
