After having my camera lock up yesterday when I tried to insert a new CF card after receiving a prompt that the one I was using was full, I have been trying everything to get my 5DII to recognize my CF cards. I have tried erasing them using my Mac since I can't get the camera to format them or even recognize them.
After hours of messing with it, I finally got a card that I had reformatted as MS-DOS FAT, and then loaded the auto exec.bin file and the latest ML folder from the nightly builds, along with the DCIM and MISC folders, to do something other than lock up. I got a Magic Lantern Rescue screen upon startup. I have tried to drag and drop, or upload the photo I took, but can't get either to work, so I will type out what was on the screen:
Magic Lantern Rescue
- Model ID: 0x218 5D2

- Firmware version: 2.1.2 / 6.9.8 A1(00)

You may now remove the battery.
