The ControlX 5.0.0 image is the best choice.

Ok. Can you please tell me what's the difference to the old version? I can't find something like a changelog.

Yes, of course :

Thank you. Thank you. If boot2 4.4.0.8 also works, then I don't understand what went wrong. My calculator installs this version automatically whenever I select boot2 to start in ControlX. This might even be advantageous.
What would happen during the installation of ControlX, if the boot1.5 version is not 3.0.0.99? That's the only thing that was wrong with my calculator after installing the OS with version 4.5. But it could always be fixed with BtMg.

It's the Boot1 which has to be 3.0.0.99, not the Boot1.5.

Oh, I see. I must have missed that. I still have a question before I buy a USB to TLL interface. It might be good to know if 3.3V or 5V is needed. I think 3.3V, but where to connect the power source?Or is it not even necessary to connect a power source directly to the calculator? In the photo with the nspire CAS I only see Rx, Tx and ground.
