On the x-box 360 it is asking for a family code and we dont know it as it was set by the previous owner, it is asking for fraviout fictional character. we need to rest it we have tried - LT RT X Y LB RB Y LEFT ANALOG STICK ONCE TO THE RIGHT A - but it is not working what should I do?

Reset all passcodes and security questions with this code:

Note: The reset code Microsoft support gives out is a unique button combo based on the 360 serial number. Best bet is to call Microsoft Support to get the code for your specific Xbox 360 serial n umber. Below is just one example of code given, but there are many.

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, 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.
