First of all you need to have dc-unlocker software installed on your PC. You can download it from here: https://www.dc-unlocker.com/downloads/get/OAnF0dvK . Then run detection of your device, how to use dc-unlocker software watch one of these videos : https://www.dc-unlocker.com/tutorials .

If possible, paste here detection information, as it might be so that your device has firmware that is not supported for unlocking.
