I happened to buy a 5D3 wich was (as I figured by now) having ML installed and removed w/o the bootflag being disabled. Now I upgraded to 1.33 and can´t seem to remove the bootflag now. Thus I can´t run an Eyefi Card in my cam 
Any ideas how I could remove the bootflag?
Thx in advance, Arndt
EDIT: ok, I figured it out by now, you can use EOS Utility to downgrade to 1.23, then use ML to disable the bootflag.
