critor, is it even possible to dump the recent (2010) Diags software.  I would think that they only made the new touchpads in 2010 that do not support Ndless. :(

EDIT: Btw are all those options in the diagnostic menu safe?


I've tested all options from the 1.1.9266, 2.00.DEVBUILD, and 2.00.1183 softwares.
At the beginning, I was a little frightened by some options like "Memory" or "UpdatedNAND512B"
But in the end, they're all safe. I didn't break the TI-Nspire.

I don't know about the other versions... I would have to flash them first.


But when you look at the dump, there are many messages that I haven't seen in the options... The "Update" word is quite frequent... There seems to be many interesting things in that software.
May be they're just disabled for some reason.

According to the above list, it seems so.
2.00.1183 from my Nspire CAS TouchPad P-0210B is marked as dumped :p

But I'm not going to explain "how" now.
And before you ask, I don't have Ndless2, not even a beta or alpha version.

Aaaah ok. Thanks for the info.

Is the diag software part of Nucleus? If it's the case, maybe it's just premade stuff that TI did not even bother removing, like most of the Nspire OS content. I wonder how small the TI-Nspire OS would be if someone completly rewrote it, optimizing it like crazy?

I also merged your double-post since it's against the forum rules (and most other english TI board)

Could it be from the emulator?

No. The "OS" (if we can call it so) and even the CPU emulation from the official TI emulators are encrypted in lib/phoenix.dll.
To my knowledge, nobody has ever managed to hack anything related to the OS with those emulators. The commands are sent to phoenix.dll, and it directly and natively interacts with the display and the documents.

Moreover, the OS used by those emulators is different from the handheld OS (some menu are disabled). It wouldn't suprise me if there were no boot1/boot2/diags in that phoenix.dll file.

I didn't mean TI's emulator, I meant Goplat's.

Well, before including the 2.00 diagnostic in Goplat's emulator, we need to dump it from a real calc, don't we ?
Or maybe I totally missed the point...

The diagnostic software is independant from the OS.

If the diagnostic software is independent of the OS, does that mean it isn't digitally signed? Thus, we can replace it with whatever we want?

It is signed independently (wouldn't it be too easy?)

If it is not signed, it would be very interesting building our own tool, some kind of hexadecimal viewer witch could modify anything in memory.

That way, if the boot1 behavior is not modified in future Nspire, we could easily patch many future downgrade protections using the Esc+Menu+G combo while powering on :P


Edit: ok Extended... I stop dreaming... :'(
So let's check what we have in current dumps.

As allready said, the 2.00 diagnostic softwares are installed on TouchPad calculators.
But, they don't even support the TouchPad keypad...

In order to have access to all options, you need to install a ClickPad keypad.
It is very easy on a basic TI-Nspire TouchPad...

...but quite complicated on a TI-Nspire CAS TouchPad.


I've managed to make it work, though.
Let's watch:

Nice, critor. Looks pretty awkward though.
At least it makes using the diagnostic software easier... ;D

Very nice critor!

Out of curiosity, what happens when you put the 84+ keypad in?
