Hi there. I have an Xbox one with Xbox live and some 360 games on it and I gave my old 360 to father in law. The 360 was flashed with ix1.6 however it has not played any backups for about 3 years or more. In this time the system has been updated to allow the playing of later releases like skyrim etc as required by the retail game disks. He never plays online games however I thought it would be nice to give him access to the 360 titles installed on my Xbox one. Is this possible via sharing live? Has the modded firmware been overwritten? Are there any associated risks? I have searched but have had no success. Many thanks.
