After downloading a few free wallpapers from the market to my new un-rooted Droid X, I noticed that I could no longer see the main screen. Every time I unlock my phone (using the swipe gesture + draw pattern) the screen goes blank and I can't see anything. Single clicking on any key has no results. The power button works fine; I could still turn on/off or put the phone to airplane mode. Interestingly, I could still bring up the camera by pressing the side button or double tapping on the home key, and I could answer incoming calls. I've tried rebooting and/or removing the battery, but that did not help. How do I use a PC to remove the free wallpapers (or any 3rd-party apps) on my Droid X? (Is that even possible?) Or performing a factory reset is my only option? Thanks in advance!
