Just purchased a 5D3, an upgrade from my 60D running ML. I see dforts post about downgrading from 1.3.4 so I can install ML on my 5D3.

I clicked on his tutorial, and the last post from 2/13/17 mentions trying to get a ML version for 1.3.4....before I downgraded, it just makes sense to ask what the progress of that is.

Thanks!

JIM

There's a whole topic dedicated to it:

Canon 5D Mark III / 5D3 / Firmware 1.3.4

Skip to the end and you'll see that just when it seemed like the bugs were ironed out Canon introduced 1.3.5 so it was back to square 1. If you want to try 1.3.4, a test build is on my downloads. This is very experimental and doesn't have a ML-SETUP.FIR which is needed to install ML so you'll have to install ML on 1.1.3 or 1.2.3 before running the Canon firmware updater. In your case you'll have to downgrade, install ML then upgrade back to 1.3.4.

Just a tip--you'll have the best experience with the 5D3.113 crop_rec_4k build.
