Has anyone had any issues installing ML on any brand new 6D with 1.1.6 preinstalled? I have 2 6D's one came with 1.1.4 installed and ML installed fine once downgraded to 1.1.3. But on the other 6D it downgrades fine but when trying to install ML it won't allow me to, it begins but slows and starts to count the percentage up to 3% then says failed, remove battery. Anyone else come across this issue? Patch maybe?
