Oddly enough, I installed the boot lag on 113. I had ML on 112 previously. So I uninstalled ML before upgrading the firmware to 113. Then boot lag the sd on 113, format card, put lastest 6d ML bin, and it worked. Beside the camera freezing/jamming at random when recording videos, there's was no other problems.
I now uninstalled ML and the camera seems to be fine. I'll downgrading to 112 when battery is fully charged.
