If you have no service you may need to flash NV backup of your phone's CPU which you may find here: https://www.dc-unlocker.com/firmware-catalog - DC-phoenix support area accessed from the software itself. In search type in your CPU such as Kirin980 etc, to see available NVbackups.

Can not guarantee this, but since the same loader works on both 710/710f it would be safe to assume that this would as well.
