[Bluko]

Hey guys !
I´m using my Canon Eos 550D and i tried to install Magic Lantern several times, but it still dont work!

i did all the steps described with my 32 gb sd card and i also have the 10.9 version installed on the camera,
but theres always a blinky light or the message i have to udate my firmware, but i´m already using the one that is needed and i dont know what to do now!
If anone can help, i would be so super thankful !
Greeting from Germany,

It's not the first time ML is working this way. Download and install Canon firmware 1.0.9 linked in Installation section. Yes, I know ... but there is 1.0.9 and there is 1.0.9. ...
Retry installation after "update" and report back.
