Double check the unlocking manual.

Direct unlock for ZTE N720
  1. Select "Qualcomm" platform from the tab menu in the upper left side of the software
  2. Go to "Unlock" tab
  3. Connect turned ON phone to PC with USB cable
  4. Install required drivers (drivers will be installed from the phone automatically) only if the phone is connected for the first time
  5. Select USB Diagnostic Port in the ports selection tab
  6. Press "Unlock" button *
