This problem happened 2 days ago, and thats when I installed the update. When I did install it, I plugged the phone in and let it install overnight. When I woke up the phone wouldn't boot, the backlight would flash but instantly go off. Now I am having a new problem, the phone turns on but shows the Samsung logo then goes to the boot screen and stays there.

It actually went to the boot screen after plugging it in, which is weird because it was charging all night. It was at 0%. It's a new battery too. The phone worked perfectly fine untill this update.
I also made a video if you don't understand my problem.
