Third-party firmware PoC...

[debrouxl]

After recently buying a Prime, I've now spent several hours making my own armfir.elf. The result is attached.
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
