@ aminnovelty,

Direct Unlock

Select "Qualcomm" platform from the tab menu in the upper left side of the software
"Phone model" dropdown box has to be set to "Autodetect"
Go to "Unlock" tab
Power the phone ON
Connect the phone to PC with USB cable
Install required ZTE handset USB driver (only if the phone is connected for the first time); in some cases drivers can be installed automatically
Select USB Modem port in the ports selection tab
Press "Unlock" button *
The message "Unlocking phone... Done" indicates that procedure was completed successfully
Wait for the message "Restarting phone... Done" to appear in Sigma dialog window; only after that you can turn the phone off

* In case of unknown firmware version detection, the software will suggest unlocking the phone using the heuristic method. Duding the extended heuristic method operation the phone will be restarted, so please wait till the process is completed. In the end of heuristic unlock mode procedure, please send the log file to our support.

** PC connection of the phone has to be set to USB (not Bluetooth)
In phone menu: Settings - Connections - PC connection - USB

Best Regards

After installing drivers diagnostic port should appear. Have you tried using another usb-port?
