Test TI-Nspire de développement avec thème CX + J04/JTAG

I think this is how they modified this calculator:

Took a production calculator and added the wire to it
Flashed the production signed uboot
Used that uboot to flash boot1 with xmodem/flash write commands

Possible.
Or maybe they just reflashed the Flash NOR through JTAG, since this calculator has the J04 connector (which is unusual for a production PCB) :

If they did that, why would they need the production uboot?

@parrotgeek1
Indeed, you've got a point.

Comsmy m'a envoyé des captures de l'OS de développement 3.0.0.1217 :

Comsmy sent me captures of devbuild OS 3.0.0.1217 :

Il a toujours l'éditeur de thème, mais plus le thème CX :

It still has the theme editor, but not the CX theme anymore :

Did he dump it? What calculator is this from? I think this is the second known "classic" 3.0 dev OS.

Not dumped yet.
Because TiLP is too complicated to install with recent Windows editions.
I gave him another way using 2 calculators, but he doesn't have the cable.

Well, having both TILP and TI's software in working state on a given computer is a matter of going through a known, described procedure, once

That has not been my experience with ANY windows usb drivers :-p

Now fully unlocked and updated, after confirming with Brandon !

Reflashed NOR with patched Boot1 1.1.9999, which can load any development/production/modified Boot2/Diags.
This confirms the hardware mode makes the NOR writable.

Flashed patched Boot2 1.4.9999, simular purpose but not as good.

Left Diags 1.1.0 with U-Boot.

Installed Nlaunch CXM 2.5 to be able to install and launch many OSes and auto-enable Ndless.

Installed OS 3.9 non-CAS + put OS 3.9 CAS image in /nlaunch/.
Both OS images have been TNOCed to take less space.

Installed Ndless 3.9 (takes less RAM than Ndless 4).

The best TI-Nspire ClickPad calculator for developers in the world !

Ready to be shipped back.
