4 The iconic Battery Logo(white background) should appear after several minutes.

Followed these steps and my phone eventually turned on
Good luck!!

I reproduced this solution and it worked!!! I think the solution here is to charge the dead battery with something that has voltage output >3.8v. The statndard USB 2.0 in the PC gives the voltage output of 5V and min current of 0.5A. Therefore, charging with PC works but charging with phone chargers which have the output of 3.8V doesn't. Enjoy!
