Hello everybody,

I can't even put my appleTv to recovery mode following the instruction....

Anybody else with the same problem ?

you must be just missing it by a second or two. try plugging the atv back into your tv and reboot it. if you see the itunes logo, you are in Df'U mode. just plug it back into your mac, and try the installation. not promises that it will go on, because a lot of people are having problems installing the older firmware, if it wasnt previously jailbroken before.
