Not if your screen isn't working. There is a reset in the settings folder. There may be one in the admin settings, but I couldn't find it and I don't really want to play around in there to much. Other than that have you tried removing the battery for about 30 seconds?

there is an option in the admin settings called DRM Master Reset. I'm not sure what it is but it might be what ur looking for. I accidently pressed it and nearly sh*t bricks cause i was scared i screwed soemthing up. It's under Admin Settings>Feature Settings.

A simple search resulted in a broad explaination that it just resets the phone to default. what parts of the phone is reset is unknown to me. As far as i could tell nothing changed in my phone. Good luck.
