offcamber said:Found this thread while googling "dead 7d after firmware 2.0 update". So I updated my 7d a couple of days ago to FW 2.0. It seemed to work fine and then tonight I turn it on and an error flashed on the LCD. I turned it off and then when I turned it back on, nothing happens. It's dead as a rock. I'm a little pissed right now. Tried removing the backup battery and letting it sit, but it's still dead after putting them back in. Replaced the CR1616 and nothing. I'm guessing there is no way to remove the new firmware since I can't even get the camera to turn on. I guess I'll call Canon tomorrow and see what they say.

Last time out the 7D just stopped working and would NOT turn on. Remembered this thread and took out and then put back the battery and the camera came back on. I'm absolutely sure this is due to the FW 2.0 update. Haven't installed the newest update yet.

i am not sure if this is the case but update a new version 2.0.3 will probably solve your problem "fixes a phenomenon in which the camera stops working when the auto power off setting takes effect."
here is little more details about it http://www.canonrumors.com/2012/09/canon-eos-7d-firmware-2-0-3/
