Magic Lantern installation in C mode

[JFG]

Hi everyone one,

Could someone tell me if it is possible to install ML while being in C mode? My 60d got bricked (Err 70)and I can only open it under this mode. I was able to upgrade the firmware but when I launched ML installation process, I got the Err 70 again before getting the green confirmation screen.

Is it because I'm in C mode or could it be something else?

I would like to get ML in order to get a crash log.

Thanks,

JFG
