I did a system update on my android. It started to restart its self every now and then or it will light up and back off 5 times then shut off. Then it started shutting it self off and I would have to turn it back on myself. 10 last night it shut off and I cant get it back on. It wont even vibrate to show that its trying to turn back on. What is the problem and how do I fix it?
