4s not functioning normally after changing battery
It was simple to change the battery following instructions from this website. Charged briefly up to 100%, and held at 100%. The phone worked great for two days. Ecstatic!! Then in the middle of showing a photo from the phone, the screen went black. It was completely dead, instantly. Charging it took some time, and while charging, it would vibrate maybe every 15 - 20 minutes. Finally got to 100%, but power button on top of phone might function to open the screen, but might not. Finally got a normal screen, and it said an update was needed, so went ahead with the update. Now all I get on the screen is the itunes circle and below that the symbol for the end of the charger cable pointing to the itunes circle. None of the buttons function now. So...what happened after two days of use following the battery replacement. Help? Please??
