Hi is possible recover boot1, I have the big problem with not working calculator. Thanks so much.

Hello.

Your Boot1 doesn't seem to show an error message on the picture.
What's the issue ?
Frozen ? Reboot-loop ?

[ironblack15]

It does nothing, it stays like that and the calculator doesn't start.

[critor]

Thank you for your reply.
That's strange.

It's quite acrobatic, but you should try to :

• hold together the 3 following keys together :

  esc

  menu

  -

  (the substraction operator near +, and not the negative sign)
• without releasing any for these 3 keys, press and release the reset button on the back

Does the boot1 then behave differently ?

[ironblack15]

Hello, thank you very much for your response. I tried the key combination, but it remains on the same image and there is no change in the screen. I tried connecting it, but the connection software does not recognize it. How can I reprogram or recover the boot? Thank you very much and sorry for the inconvenience.

just followed the guide and it did work but it seems that none of the the cas calculation patches are no longer avalable what should i do?

[critor]

Thank you for your message.
The files are still available, but the external links suddenly became invalid for some reason.
I did update them.

If you need some disabled OS patches, enable them in the Makefile, maybe disable some other ones, and rebuild ControlX.
The patches payload has to fit within the Boot2.
Current payloads are compatible with Boot2 4.0.3.49 and 4.4.0.8.

If your ControlX setup is based on Boot2 4.0.3.49, then the current CX+CXCAS payloads already take almost all exploitable space. You'll have to disable some patches in order to be able to enable new ones.
If your ControlX setup is based on Boot2 4.4.0.8, then you still have around ~100K more exploitable space. You can probably fit 1-3 additional patches before needing to disable some other ones.

If you are still using Boot2 4.0.3.49, then you should update it to 4.4.0.8 - it's so much better, for the exploitable space for payloads, but also for modders who turn their TI-Nspire CX into a TI-Nspire CX CAS (no reset mandatory on completion of the first boot of a newly installed OS).
