5D mark iii freezes when upgrading ML firmware

Issue #1815 invalid
Simon Cote created an issue

I am trying to install ML raw firmware on 5d mark iii.

I've followed every steps.

Copied Autoexbin, 5D3bootflag-113.fir and the ML files Made the SD Card DSLR Bootable on Macbootclass (successfully prepared) I've put the card back in the camera then tried to upgrade the firmware and it says that the camera is not finding any firmware upgrade then freezes. When I turn off the camera the image is staying. I have to pull the battery out to close the camera.

What am I doing wrong ?
