No, you cannot make the Xbox One backwards compatible

Posted Dec 8, 2013

There is a rumor floating around that you can make the Xbox One console backwards compatible, but this is not true. The rumor said that backwards compatibility can be enabled by turning on developer tools. Take caution if you turn on developer tools because your console could be bricked.

To be clear there is no way to make your Xbox One backwards compatible & performing steps to attempt this could make your console inoperable
