Warning over 4Chan Xbox One prank

Props to Microsoft for opening up the devkit to everyone. It's not their fault that some people just love screwing other people over.

The iOS7 waterproof upgrade did make me laugh.

My question is, how did anyone find out this combination? Is this part of the documentation that anyone can get, or is there a rogue Xbox developer out there sharing this information with 4Chan trolls?

Found the &quot;instructions&quot; (obviously don&#x27;t follow them): <a href="http://i.imgur.com/7HZxhzT.jpg" rel="nofollow">http:&#x2F;&#x2F;i.imgur.com&#x2F;7HZxhzT.jpg</a>

Microsoft&#x27;s fault for letting user the possibility to brick their console. Does it void the warranty ?
