I also followed the same but not working for me. Anything I am missing?
I did get the 6d Nov. 30, 2013 build installed and working. Whew.
However, it was a rather "lumpy", trial-and-error procedure. Two steps forward, and one step back.
IIRC, it took several attempts after getting firmware 1.1.3 down-graded to 1.1.2. I don't recall the exact steps that finally resulted in TL being operational ... I was pretty much just trying something, and hoping for the best, and that the 6d wouldn't brick. Very nerve wracking.
My speculation is that glitches with EosCard.exe 1.3.2 were some or most of the problem? Operator error?
It was not a procedure I look forward to doing again. YMMV.
