Title: Mod your prototype Nspire into a production one
Post by: critor on November 20, 2011, 12:20:12 pm: We did it! Today is a great day we shall remember of with the rage comic below:

(http://tiplanet.org/forum/gallery/image.php?mode=thumbnail&image_id=286) (http://tiplanet.org/forum/gallery/image_page?image_id=286)

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:

(http://tiplanet.org/forum/gallery/image.php?mode=thumbnail&image_id=291) (http://tiplanet.org/forum/gallery/image_page.php?image_id=291)

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.

Post by: Juju on November 20, 2011, 01:42:14 pm: That's awesome! So if you put an OS with the wrong keys, what about third-party OSes?

Post by: Jim Bauwens on November 20, 2011, 01:44:09 pm: It will be possible to have third-party OSes on prototype models, so that way they are more cool than production models :)

And with older prototypes, is it possible ?

Not for the moment.

The Boot2 is the regular 1.4.1571. So it does check for the OS production signature, and for the CAS/non-CAS model ID.

So this prototype currently only accepts non-CAS production OSes and cannot be easily downgraded back to a developer OS any more.

The current mod has nothing to do directly with running a 3rd party OS.

Post by: critor on November 20, 2011, 02:45:54 pm: Yes, that's what I was thinking about.

But unfortunately, no hope for TI-Nspire CAS+ owners up to now :(

There's some blue around the edge of the calc in the inset..

All modding tools have now been released on TI-Planet, and the tutorial is going to be released soon. :D

What was the trick?
On Nspire prototypes, the Boot1 can be erased and reprogrammed because of just one additional pin connected.

Just imagine what could be achieved on production Nspire if someone managed to connect that pin...

Or, how was it programmed without that connection ?

Edit: Maybe by production time they were programmed on a machine in an assembly line fashion, then soldered on the board .
