The code fills one third of the screen with red, one third with green, and the last third with blue (with some glitches...), then enters an infinite loop. Yeah, this PoC sucks, I know - it sucks just as much as my Nspire DummyOS did, more than three years ago.

Usage: copy the armfir.elf file into APPSDISK.DAT. Firmware transfer, enter recovery mode by pressing the Reset button in the hole on the back, pressing the Symb key, releasing the Reset button, and holding Symb until the Recovery mode screen appears. Then, use usbtool (Windows only).

As usual: works for me, but use at your own risk

There's a thread about prime hacking @ omnimaga that recently became more active again.

Parisse even deigned to make a few replies, more or less along the lines of I can't tell you much about how the proprietary firmware works, but I can probably drop hints to help hacking, or so I read it.

Seems like omnimaga's down ATM, but this SHOULD be the link to the thread:
