well let me ask you a question... why do you need it anyways? you can't use 1seg outside of japan so it useless if you don't live there....  yes your gonna have to get the main tv icon somehow... it only shows under that.. i don't think the firmware installer puts all the files for it on the fat due to lack of flash size... if you just want it to say you have, its seems like alot of trouble for nothing really.. i mean maybe you could hex it to point to something else other that 1seg to run something else but that would be the only use on a fat
