IF the installation failed, a HARD RESET will bring the OS back to where it was ...

a HARD RESET may also fix the failed install - you won't know until you try it.

IF phone is non-operative, either plug it in to PC & use Windows Phone Recovery tool (make sure you have the latest version) ...
OR search this forum for HARD RESET key combination.

Good Luck.
