So i changed my phone battery, but when i turned my phone on it was on 20%, i charged my phone and it remain stuck.. I did the volume+ power button and didn't work, restared my phone didn't work, drained the battery and charged it while off, and then turned it on and restared it and still didn't work, and i also pressed the button near the sim card.. I even did a factory reset and still nothing worked. What should i do??
