We did it! Today is a great day we shall remember of with the rage comic below:





What's all this about? Do you remember the ClickPad Nspire prototypes whose Boot1 & Boot2 were using developer RSA keys instead of production ones? The protypes on which you couldn't install productions OSes from TI website? The prototypes where you could only intall some prehistoric 1.1 & 1.2 developer OSes available only on TI-Planet?



So, check this:



It's a P3-DVT2.0 basic Nspire prototype originally running OS 1.1.9227. And here it's running OS 3.0.1.1753 without any problem.



In theory, every TI-Nspire ClickPad prototype can be modded into a production Nspire and accept production OS.

You still have some Nspire prototypes in your desk? Consider that you'll have a new Npire in some weeks when the tutorial and the required tools will be released.

Could you show us a photo?

Can't be sure if this is related or not, but Excale spotted me the disappearance of R02D near the NOR chip between the prototype and production model:

If this is the reason, I don't think we can fix that

So we have assumed in the above posts that the Boot1 on prototype Nspire ClickPad was rewriteable (which is a very good news if right, and a wonderfull hope for those owning such models currently limited to OSes 1.1/1.2 because of different RSA signing keys).

The only remaining question was if it was also possible on production Nspire ClickPad.

Here's the same Ndless program running simultaneously on a prototype (on the left) and on a production model, trying to get the NOR chip ID:



On the left it does pass.
On the right it does fail.

Which would mean if the test is correct, that TI added some software/hardware protection on production Nspire ClickPad models, preventing direct access to the NOR chip.


Wouldn't that mean that prototypes prices should raise on eBay soon?

The game is available on TI-Planet and linked at the end of the news:

You've dreamed of it?

Levak made it.



The 1st real homemade Nspire dock connector with all 26 wires.





Just imagine everything you could do with that:
- power external peripherals
- connect a 2nd USB port
- power your Nspire externally
- connect a SD card reader
- connect a WiFi module
- ...
