[求助]如何在TI－Nspire CM－C CAS上使用nlaunchy

ssaalkjhgf

我的计算器是TI－Nspire CM－C CAS，OS3.1.0.392，想刷OS3.1与OS3.2（3.2增加的几何的工具还是很好用的）双系统。曾经看见Tiplanet上面放出过适用于Nspire CM的nlaunchy包，但是不太明白如何使用。求教。

It's quite tricky.

You need to partially mod your TI-Nspire CM into a TI-Nspire CX.
In that state, the calculator will be semi-bricked, as it won't be able to install any CX or CM OS directly anymore - but you'll be able to install any CX/CM OSes 3.0-3.3 with the help of Nlaunch CXM.

Using nsNandMgr, you need to :
- in the Manuf options, switch your CM model ID to a CX model ID
- flash the CX Boot2 3.1.0.16

Your original CM OS will be removed on the next reboot, but you'll then be able to proceed to the Nlaunch CXM installation.

Thank you.
If I did that, is it possible to undo all the operations above to recover my CM-C CAS to the original condition?

If you don't make errors and manage to install Nlaunch CXM, yes.
You'll be able to reinstall Ndless, and revert the process with nsNandMgr.

If you make any error, the calcutor may be bricked permanently.
