guys, my phone isn't getting charged. i tried connecting to wall charger via convertor, i tried usb charging but to no avail. i keep charging my phone for 2-3 hrs straight and it only gets charged upto 12% and dies fast. i recently installed android gingerbread in mmc 4gb, and i cleared the device, restored original settings before this had happened. is this the source to the problem? pls help me.
