Hello Anirudh Akash, its seems to be firmware corrupted on your phone. check whether it detect by from PC, if PC detecting your phone or installing drivers you can install kies and try to update firmware via kies

it is not powering up and it is nor detected by pc or by kies and neither by odin.. it all dead.. nothing is working…. its not even going into download mode or recovery mode.

The mobile is self-charging without connecting the power supply

have you tried replacing the battery? if not that then maybe its a screen or motherboard problem

I have the exact same problem. I gave up on the phone along time ago, and i have realized both of us have done, is bricking the phone completly. i cannot find a solution either, but i dont think you can fix it.
