did you try what @nokiamodeln91
Take battery out for some time. Then power+home+volume down ?
Just a thought your battery is fully charged or at least 80% charged?
I am very much also in the learning curve but will try to help if I can.
I have learned to follow advice from users like nokiamodeln91 to the letter.
Shalom and best wishes, john
a soft answer turns away anger as rudeness turns away potential users.
