I think I posted in the past that I thought that the hardware was the same in regards to CX, CXi and 3300mx. I was told that these potentially are different.
I just got a 3300 CXi for parts. I came with v9 software. I flashed back and forth between 200 and 3300 several times. My thinking is to make sure all is flashed to proper settings, as this looks like it works.
YMMV, just letting you know what I see on the bench.
