So this happened today when I was planning to ship my phone to my cousin. To send the phone through air service I had to drain battery (weird rule in my country) if its an inbuilt battery hence I tried a never before method and used a Battery Drain app from Google Play.
Now after raining battery by 20% and phone turning super duper hot, I decided to uninstall the app and so I did and formatted the phone. This is the point from where things went downhill...after the phone restarted, "Home" touch key stopped working and I started getting error about "Lock Screen crashed" and wifi is stuck at "turning on" and *#06# shows up blank.
I tried rebooting and formatting it multiple times with no success.
Also tried Vol + power and tried every possible option from there with no success.
Did anyone here had a similar experience? If yes how did you resolve it?
