Replaced battery, no charge, no reception, no wifi
So I just replaced my dying battery with a new one only to notice it wouldn't keep a charge (works only when connected to power outlet and shuts down when disconnected).
There's no service or wifi as well.
I double checked and tested all the connections and when I replace the new battery with my old one (which still has some juice left) everything works fine.
So I'm quite sure this isn't a connection problem.
But what is it? Is it the new battery not working correctly?
I was expecting this to be easier and more troublefree than it is now.
Thank you for your help.
