It seems the AF chip needs a firmware updated to use on your 5D3. You can change the focus screen of your camera http://www.focusingscreen.com/work/5d3en.htm or you can use the Magic Lantern addon to help you focus http://forum.mflenses.com/canon-eos-magic-lantern-addons-t62601,highlight,%2Bmagic+%2Blantern.html . Someone here should have hand-on experience for sharing.

Your chip is not compatible with the 5D Mk III. There is nothing you can do other than remove the chip, or buy a compatible one.

I currently have 3 chipped MF lenses and all three of them work with my 5D Mk III.
