Hello,I really love this awesome FW, it make every thing easy when I use my old YASHICA lens. about 3 weeks ago, My 650D send to canon to clean,I borrow a 600D from my friend, and I install ML on his 600D, But he told me uninstall ML totally before I return his 600D,because he just take photo and don't need ML. So I want to know, How to uninstall ML even BOOTDISK flag in camera.(I know I can uninstall by format SD Card and Clean all user setting in canon menu to clean NVRAM,But it still BOOTDISK flag in camera,right?) BTW,I'm still study in university, my major is Electron Technology,and I have a part-time job work with Embedded system:)
