DO NOT follow the instructions below. We think they first appeared on 4Chan as a way to enable backwards compatibility for the Xbox One. In fact what they’ll do is simply put your Xbox One into an infinite cycle of reboots. Not cool!
The steps, which involve enabling development mode on the Xbox One, were originally posted as a way to enable backwards compatibility for the X1 (a feature left out, but that could arrive in years to come courtesy of the Xbox One cloud).
Instead all they’ll do is most likely brick your console. So we repeat, if you see them posted anywhere (even with other people saying it works) do not believe it! There is no way to enable backwards compatibility for the Xbox One and what’s more, playing around with things like development mode will only lead to tears if you don’t know what you’re doing!
