RE: cannot upgrade or downgrade from x.83.0.55 firmware
I am having this issue! I think I found a fix. Grab the 66.84.0.35 firmware, flash to that first.
https://downloads.3cx.com/downloads/v160...4.0.35.rom

From there it's looking like it's accepting the .95

I've had something like this before, but this one was super crap. It took looking at another install and seeing what firmware those phones where on.
