I thought to move your thread to the general forum for the S3 vs. the rooted forum
I just want to share a similar story that happened once to me. Similar story.
My phone was at approx. 40% battery left, and suddenly turned off.
I had no response at all from the power button.
I took out the battery like you did etc etc...nothing.
Just for shits and giggles, I did this out of frustration: (in no particular order because I don't remember--I was frustrated lol)
I removed and inserted the battery rapidly (enough for the contacts to make contact)
I plugged it into a wall charger without the battery, then put the battery in.
I unplugged/plugged in/unplugged it rapidly--maybe 5-7 times(at the phone port) (with the battery in).
I finally got a red, charge light. I left it alone for 10 minutes and booted it up.
Yeah, I almost threw it across the yard
