I got my Sprint M8 just few hours ago, rooted, .S-ON.

At first it worked fine, but after left it in my pocket for about 30 min with about 45% battery power, the phone powered down by itself, and there was no way to power it on again.

I tried to charge the phone with the stock charger for more than 3 hrs, the screen was always showing an empty battery logo with a flash icon inside, no green charging indicator, and the orange LED beside the speaker was blinking all the time.

I also tried to push Power+Vol up for more than 20 seconds, still nothing happened.

Is anyone know how to fix this?

Push Power + Vol up again, but this time hold the phone under a bright light, in particular the area of the front camera and sensor needs to be under the light. Keep holding down until it reboots.

20 seconds isn't enough ... once I had to hold it for about a min before it jumped back to life

Try to hold it for more than 5 min and no chance to boot it.
