T679M unlock problem please help


I have tried many times to unlock T679M every time z3x shows

Selected model: T679
Selected port: COM30 SAMSUNG Android USB Diagnostic Serial Port (WDM)
Selected port speed: 115200
Reading phone info... no answer from phone
Done with Samsung Tool v.16.3

I have tried this method:

1. enter *#7284# and select MODEM, restart the phone
2. enter *#9090# and select USB, restart the phone

now connect phone to pc, install drivers..
In Samsung tool 11.6 select model T679 and under port select Samsung Android USB diagnostic and click unlock...

but not succeed





I have also changed usb port...

also tried with rj45 C3300k cable...

but still the same result
