I downloaded fifa 14 RF squads update and title update and copied it to my xbox partitioned external hdd via a software called horizon. After that when I put attached my hdd to my xbox, it did not get displayed. The LED on the hdd lights up but the xbox wont show it.
i assume you are using an rgh/jtag? if it's going onto a external hdd, use 360 content manager to ftp it to your rgh console. it will put it in the correct location for you.
