Hi,
I also found ML only after I have had my camera already updated to 1.1.0 firmware.
But I didn't have any issue downgrading the firmware to 1.0.9 version.
What I did:
1. Format my SD card (low level).
2. Copy 1.0.9 fir onto it and downgrade firmware on camera.
3. Format again (just in case).
4. Copy ML (build from 19.12.2016) and perform firmware upgrade on camera (in a second).
5. Reboot and enjoy.
Big thanks to the ML team.
