I just installed Magic Lantern on my 5D Mk II, it said to restart the camera, which I did. Then I shut it off and took out the memory card and dragged the backup ROM files to a safe spot in the computer. I put the card back in and tried to boot and nothing happens. It's like a dead battery, but I know that my battery isn't dead cause it was running a second ago. I tried 2 other batteries as well. None of the LEDs light up or anything.
I read in other posts and attempted removing the Lens/Battery/Card and booting but I still get absolutely nothing. I tried downloading the diagnostic autoexec.bin files and they don't do anything either. I tried booting on each mode.
I have not attempted to format the card yet, and it's the only CF card I have. I did make a full copy of all the files on the card (simply by dragging them out to a folder on my PC).
Pretty worried at the moment, could really use some help.
Update: After reconnecting my grip (which was used during the install), I am able to get the camera to boot by ensuring there is no card in the camera, the card door is closed, and removing and inserting the batteries. Not sure if I should just format my CF card or not. I know if I try to turn on the camera with the card in, nothing works.
