[HELP} Can't boot my S4 up after a battery drain
Please help me figure out how can i boot or at least make my battery charging LED turn on...
Scenario: I leave my phone downloading some files while charging at 5%. But then when i got back, my phone is already dead... Can't boot up, that's maybe my battery get drained... I have tried reviving my battery using a clip charger, tested it with a AC/DC Tester and it shows its already fully charged.. But then when i get back to my phone, it won't even start, can't go to the recovery, or even no light even if it's plugged.... Please help...
