I am planning to use patchstick solution to hack the appleTV , mainly for divx/xvid compatibility. I would like to know if someone has hacked it and then restored it to factoty default, essentially removing hack. I have read few reports about this, some say since appleTV OS is on hard drive partition which can not be deleted, you can always restore the original state whenever you want. but, some have bricked their appleTV too. So, I would like to know if which software hacking is "fully restorable" and which one can brick appleTV if you try to restore to factory conditions. I would assume since its software hacking and assuming it does not screw up firmware, it should always be reversible.
