Ok, new ControlX option let you switch your calculator between release and development modes :

In development mode, you can install and run development OSes, like the CX 3.0.0.1045 OS with the integrated theme editor. :bj:

This is done by patching the 2048-bits RSA keys used for validating TI-Nspire.cer in the Boot2.

It should be possible to install and run CM OSes soon, as the problem is also related to different RSA keys.

3.0 DVT OSes were dumped on prototypes.
TI did share DVT OSes privately for the first and last time in 2011, versions 3.6.

I apparently didn't manage to convince them, since I never got more recent DVT Oses.
