I've been playing around with different things people have been doing to dump their camera's firmware. The firmware version looks like DryOs, I'm getting version GM1.00 d (or something similar, don't have the camera with me at the moment) using the ver.req method.
Placing an empty ver.req file on the root of my card, turning the camera on using the playback button, then holding down "func/set" and then pressing "disp" will give you the firmware info on the LCD.
Also by making the SD card bootable, placing the pre-blinker files (PS.FIR and DISKBOOT.BIN) on the root of the card, and locking the card(this is key) will cause the camera to hang.
This is as far as I got, I'm still trying to figure out where to get a arm's compiler and how to how to get the led address's to blink it out.
If anyone can lead me in the right direction on what should be my next steps, I will try it out.
