Xbox 360's with 500GB and FIFA 15 pack are incompatible with RGH
Seems Microsoft has released a new Corona motherboard layout that is using a smaller die and new traces and Nand setup, as such it is currently not possible to RGH (mod) these new Xbox 360 consoles!
Looks like Microsoft is still improving the Xbox 360 console, releasing yet another new model, and because it is new PCB layout with a smaller die chipset, it is sadly incompatible with the current RGH hacking setups, leaving those buying these new Xbox 360 consoles unable to mod them...
A method to unlock the debug mode on a retail Xbox One has been found.
Some proof that Microsoft's statements that 'every Xbox One can be used for development' is true and maybe will encourage indie developers
This method may not fully convert a retail console into a dev kit but it could possibly help some small developers that can not afford to purchase a full dev unit to get started on making some ideas started.
