Warning: Resetting your console to its factory defaults erases all accounts, saved games, settings, and home Xbox associations. Anything not synchronized with Xbox Live will be lost. Your console syncs with Xbox Live automatically when it’s connected with the service, so if you've been offline for a while, connect to Xbox Live before taking these steps.

If you’re ready to reset your console to the factory default settings, follow these steps:

1. Press the Xbox button  to open the guide.
2. Select Profile & system > Settings > System > Console info.
3. Select Reset console.
4. On the Reset your console? screen, you'll see three options:
   • Reset and remove everything. This option resets the console to factory settings. All user data, including accounts, saved games, settings, home Xbox associations, and all games and apps will be deleted. Use this option when selling or gifting the console, or as a last resort in some troubleshooting cases.
   • Reset and keep my games & apps. Use this option as your primary choice when troubleshooting. It will reset the OS and delete all potentially corrupted data without deleting your games or apps. In some cases, if a corrupt game file is causing the issue you're troubleshooting, you may have to choose Reset and remove everything, but you should always start with Reset and keep my games & apps.
   • Cancel. To back out of this screen, simply select the Cancel button. No action has been taken at this point. This is a safe exit from this screen.

The only way to completely start over would be to create a new account. There's no way to reset an account.
