Great work guys! One more question: How can I install this Magic Lantern-version on a second and a third SD-card? Do I have to do this steps again or do I have to repeat all steps from number 1? Thanks!
"By noisyboy:
8.5: Seriously, FORMAT YOUR SD CARD DUDE! Even if you are used to this whole Magic Lantern thing - just do it. It saves the risk of potential problems which I can't advise you how to fix.
9: From the zip in step one, extract the Canon 1.1.3 Firmware and place onto the route directory of your SD Card.
10: Put your SD Card back in your 6D and With a full battery, upgrade your cameras firmware to 1.1.3 as per the Canon 6D instruction manual. Once this is finished, power down camera and remover the SD Card.
11: From the zip in step 1, once again extract and run EOScard.exe. Check the EOS_DEVELOP and BOOTDISK boxes and press save.
12: Navigate to your SD Card and delete (DON'T FORMAT) all the files you can see there.
13: From the zip in step 1, extract all of the files and folders contained within the "Files to run Magic Lantern on 6D Firmware 1.1.3" folder and drag them into the route directory of your SD Card.
14: Put the card back into you camera and switch on.
15: In "M" (MANUAL) shooting mode, power camera back on and hit the Trash button. Voila! Hello Magic Lantern Menu"
