All you can do is to take it back to factory settings. Turn it off then hold he Volume Up button while turning it back on. A menu will show up - if it includes Safe Mode scroll down to that option using the volume up and down buttons and the pwoer button to select the option. If that options isn't there, select Factory Reset.
