I just updated my 550d from 1.0.8 to 1.0.9 and when I dropped the ML FIR v.01.6 and CFG files to my memory card and put it into my camera and try to update it through the menu it says: Update file cannot be found. Please check the memory card and reload the battery and try again.
I've tried again and it didn't help. I remembered to format my card, but it simply won't work. Any one know how to solve this issue?
