X420MM10k_00_MPCS_US_OP_0923.kdz

This stock firmware for your phone. You can't unlock your phone via firmware. You need use Device Unlock App from phone menu.

Maybe problem with dll. You need download kdz extrator and unpack firmware and put dll file in LG UP folder.

Navigate to LGUP install directory (default C:\Program Files (x86)\LG Electronics\LGUP) and simply replace the 8994.dll in model\8994 directory.

8994.dll  is for example.

This don't work with LG Flash Tool. LG Flash Tool for too old phones.
