Help needed on mark III installation

[neom315]

Hello all

im newbye here, i have tried to go trough the post, but i am a bit confused so someone would be that cool to help me out on that.

I have being trying to install the august night build to test the raw feature of ML, i have "prepared" the sd card with eoscard to be bootable after i had activate trough the .fir the bootflag option, now problems starts.

during the installation of ML i got "sd card test failed, dont use sd card with the 5d markIII" and ML doesnt install, i had then the take the battery off and so on to be able to use the camera.
so now i have two questions

1) does exist a way to disable the bootlag without giving it to canon?
2) why the hell i got this message in first place? the card as being readed and was working with ML 2.3 before activating the bootlag.

Maybe someone can be that kind to help me out
thank you

1. No
2. Maybe your SD card is damaged.

Using a card reader do a format to fat32
Put the card in the camera and turn it on
Your camera should boot normally to Canon
Now format your card with camera
