After updated to 17150 kernel. My Xbox can only boot to the official dashboard, not Freestyle. I've modified the launch.ini to my usb0: path, still unable to boot to my external USB HDD. I found out that official dashboard is unable to detect my usb hdd. I tried to format another 16G USB key with FAT32 and it's unable to detect it also. Boot from XELL and unable to boot from USB key with any default.xex. I am Noob on this. Please help and advise.
