If your HTC device is on Marshmallow or Nougat then it can be unlocked only using Reseller Tools.
Please follow the steps listed below.

1.) Download and install our app from here, directly from your phone.

2.) Purchase the HTC unlock license from within the app, then close it.

3.) Go to System > About Phone > Software Information > More > About > Software Information > More and tap "Build Number" 7 times to enable "Developer Menu",
     then enable "USB Debugging" in the Developer Menu.

4.) From the phone dial: ##3424#

     Note: On some devices the above code doesn't produce results, if so you need root, connect your device to a PC through adb and use the following workaround (thanks to marhinal88 of XDA):

     To set DIAG Mode ON:
     echo 1 > /sys/devices/virtual/android_usb/android0/f_diag/on
     Now you should be able to dial: ##3424#

     To set DIAG Mode OFF (when done with the unlock):
     echo 0 > /sys/devices/virtual/android_usb/android0/f_diag/on

5.) Move the switch to set DM enabled.

6.) Connect the phone to the PC using an USB cable and wait for all drivers to finish installing.

7.) Browse into the phone folder and copy the IMEI.unlock file to somewhere on your computer (Desktop is fine).

8.) Download and run Reseller Tools (Password of the archive: Be sure the phone is still connected to the PC.

9.) Select your IMEI.unlock file, wait a few seconds, the tool will download the license.
     Unless you aren't a reseller don't worry about the credit file selection, that part is just related to our resellers.
     Select your IMEI from the "Approved IMEIs" box.
     Check the to the right panel, click on the Get DM Ports button, it will become HTC unlock button, click on HTC unlock, phone will be unlocked.

10.) You should be greeted with Unlock Success message.
