For one reason or another lots of people end up with a 360 with an unknown parental lock blocking their full use of
the console. This is a great thing for keeping children away from any potentially harmful adult media but once it's on
time though and apparently Microsoft's tech support on the subject isn't easy to get through to either so here's what
you can do to get around it yourself.

The following instructions come from a forum post by "Exthero" on the xbox-scene.com website and it's been
absolutely proven to work for a lot of folks so many thanks to those guys for providing this solution to the problem.
I've copied it down word-for-word here or if you need to you can click on the link below to go directly to the post
itself.

If this fix just won't work for you you'll probably have to contact Microsoft at 1-800-4MY-XBOX  and get them to
give you the correct "code".  This might mean a 45 minute wait on the phone but that's still a lot better than
permanently having to live with a partially disabled console.
HOW TO REMOVE AN XBOX 360
PARENTAL CONTROL
I hope this worked for you and thanks again to www.xbox-scene.com and Exthero for posting something so helpful for free. I'd
like to say though if this originally came from someone else I do apologize for the oversight and I'll gladly post the correct credits
if someone let's me know about it. Thanks, Lynn
