New 6D: ERR 20
i just received my 6D, but it seem broken.
impossible to take a photo, each time i press the shutter button i get an ERR 20.
i tried a different battery, with or without lens, card, etc.
but nothing, ERR 20 all the time.
i flashed the firmware to 1.12: but no way to take a shot.
the mirror dosen't flap
any suggestion before to send it back?
