[Tutorial] - Fixing a bricked system

[Deak Phreak]

I am not sure how to find the actual version from the firmware. You could try mounting it from the SD card and then running the "boot up" script to see if you can get the device to load before actually flashing it. I don't know all the commands off-hand though. You can also try flashing your dump to sdcard6 and see what happens.

is0-mick could most likely help out further in the IRC though.
