How to install files in off mode when phone is completly flashed

I updated my phone (Galaxy Note model SGH-i717) from 4.0.2 version to 4.2.2 version (Kitkat version) and deleted all the data in it and tried to restore it. But every time it showed that restart failed and phone is not getting on now. I am not able to do hard reset/factory restore as my phone is not switching on. when I am trying to restore/ factory reset it simply shows that "Factory Reset Failed" How to restart my phone and again upload necessary files and softwares in it. Please help.
