Many people have asked how they can reset the family timer settings and/or the passcode on their Xbox 360 console. I have the answer! No cheap tricks! Reset all passcodes and security questions with this code:
1. On the 360 dashboard, scroll over to the "System" tab.
2. On the System tab, click "Console Settings".
3. Scroll down in console settings and click "System Info".
4. When the system info box comes up type in this sequence:
LT RT X Y LB RB Y "Left Stick in" (press it in) Y Y
A box should come up and say, "Would you like to reset the console to the factory defaults?"
Click Reset and you're done!
If this doesn't work, and that's highly unlikely, call Microsoft at 1-800-4MY-XBOX (U.S.). Provide them with your registration info and they will tell you how to reset the console.
