T800 – software not working

I have problem with service Samsung T800, i tried to use any function but always not working, spt sw says only: Total Time: 0.0 s
I tried by Uart Cable and USB, always not working. There is no error code or reason in software only Total Time: 0.0 s. I’m new SPT user I usually use z3x or Octo, and on thats sw samsung is visible but the are no desired functions. I use SPT box on UST box, because there is no win7 x64 drivers i used card on z3x box and nspro box, still the same.
