It doesnt work… .
follow the instructions (which are too breif) and get to the point where your supposed to ‘Restore’ the V2 using the file… but it just restores it back to factory default 
After about 4 hours of trying I want a refund.
V1 apple TV worked first time.
Found a way to get it to enter DFU mode everytime… or at least thats what SeasOnPass responds to.
Plug in Power,
Plug in USB,
Remove power,
Hold Menu and Play for 7 seconds.
Used Sn0wBreeze - worked first pop!
When it says fail, go to iTunes and hold down alt when you click restore, then find the file Seas0nPass created and select it… boom, solved. Pity support couldn’t tell us that.
