I put magic lantern on my 5Dm2 and it worked, until I turned it off, and tried to turn it on again. My camera was completely dead. I had a shoot the next day so I stayed up all night trying to find a solution. I changed the card and pulled the battery, then retried. Ahhh, thank god! But now, my 16G card is useless and I cannot reformat it because my camera is a brick with it in. Any solutions? Much appreciated!
Reformat it in a PC or Mac
