On this tablet (not mine, but a customer's), as soon as they power it on, and do the slide to unlock, it says "Sorry! The process android.process.acore has stopped unexpectedly. Please try again.". When I click the "Force Close" button, the home screen crashes, and it comes right back up. My computer is not detecting it when I plug it in with the USB cord, and the icons in the background are not responding. The lock screen functions normally, and it otherwise cannot get passed this screen. Other forum posts tell me to go through settings then... Wait, I can't access anything! Is there a secret method, maybe a Safe Mode, I can use to log in and troubleshoot this?
