So my Droid 2 Global won't charge when plugged in using the provided wall charger, but will using a USB cord into a USB wall charger. When I plug in the wall charger, it turns on the welcome screen as always, but does not charge. When I unplug it, it vibrates as if I just unplugged it. So I tried restarting it, which it took a while to do because a DOS looking type came on the screen saying BOOTLEGGER ok, USB charge. Changed the battery and the same thing. Any ideas what might be going on?
