So I just got a Droid 2 Global today, and I've been having a lot of problems with it. I got it off of ebay, pre-rooted and sim unlocked. First of all, it doesn't show anything at all on the home screen. It just shows a black screen. The notification bar still works, and pressing the home button brings up voice activation still. Also, it has some problems rebooting. Rebooting the phone causes it to hang at the red droid loading screen. The only way I can get it to boot is by doing a factory reset. Any ideas how to start fixing it?
