Default Can only use 1 Rom?

On my GT-i9195 LTE when using Roms from Samsung Updates Live I can only use BTU Roms?
Phone is unlocked and Have tried Orange / EE Roms for my Country but ODIN Reads says 'FAILED'
Only works with BTU

Any ideas
As I know I can flash Custom Roms (in which I have done) but sometimes like to move about
