Now the tablet is giving me error message "Start up Failed" and will not fully reboot. The rest of the messages says "Your device didnt start up successfully. Use the Verizon Software Repair Assistant on the computer to repair your device. Connect your device to a computer to get the Verizon Software Repair Assistant." Below that in little letter is says Authentication Fail #4. However upon plugging the device into the computer it will never fully connect and I can not get the repair assistant to run at all. I even tried to hard reboot and factory reset and still will not let me do anything. Please HELP as my tablet is useless at the moment?
