My younger brother, in his infinite wisdom, created a new account on my 360 (original. As in, I got it when the xbox 360 was less than two months off the press) while I was on holiday (and by holiday, I mean living with my uncle for two months) using an e-mail account he created on the fly, never expecting to need it (he was using one of the free months that come with the xbox). He allegedly had threats of someone "hacking" him on xbox live and panicked so much that he instantly set up parental controls using that account, subsequently forgetting that password as well.
Here's where it gets better. At the end of his month of live, he decided to create another account (my xbox only ever had my account made on it, so it still had a few free family accounts left on it) only to find it was blocking him from doing so, requiring him to put in a code he's forgotten, and then asking his to reset that code with another password he'd also forgotten (apparently the answer to his favourite fictional character was a string of random letters - so that nobody can ever guess it. My brother is obviously a genius at creating codes, because even he can't crack them.). During his panic, he decided that he'd try and reformat his hard-drive (he'd kept using his hard-drive on my xbox, using my xbox only for the free live). Now no one even knows how to get back on to his account, nor how to undo his idiotic parental controls.
Is there any way I can get rid of the parental control? Maybe by factory restoring the console it'self (people on the internet have no idea what the difference between factory restoring an xbox and formatting it's hard-drive is, so every nasally teenager on the internet has now told me how to format my drive)? I don't care for the account, and knowing my brother, he probably used some month-long burner account or something else that I wish I'd never taught him about. I don't want to reset the password, I just want to have a fresh-out-the-box experience with the console it'self, add a few battle scars and dust.
TL;DR Brother set parental control and subsequently forgot how to human. How do I reset the entire xbox?
