Red line through empty battery icon on Curve 8300
Symptoms: Blackberry Curve 8300 or 8330 shows the white screen and battery symbol with red line across (see screenshot below). The phone will not boot up neither with new battery inside nor connected to a wall charger. BlackBerry Desktop Software can't connect to the phone either. Solution : remove the battery, gently remove the front plate, separate the back and center pieces and clean the contact pins marked on the picture below.
