Hi and welcome to windows central forum.
Did you charge your phone prior to hard reset? maybe your battery ran down adn a shut down interrupted the hard reset.
If you are unable to restart teh process or the device displays some emotion like a sad face

you should them turn to Windows Device Recover Tool (W.D.R.T.) DOWNLOAD IT FROM HERE:>

Install the app and connect your device, the installer will then download the installation files and flash your device to a working state.
