I've tried it, but the problem (I think) is that the file smallatv.dmg (I think again) is corrupt, because I can't mount it.
dd if=/Users/vicenserralta/smallatv.dmg count=1335 of=/dev/disk1 bs=1024k
but once I plug to the tv, nothing happens.
Could someone send me the smallatv.dmg correct? thanks to everyone.
