I have just completed the uplad after many tries…Tried it on my Windows Laptop, then Macbook Air…also tried various versions of iFaith.
It appears the laptops are not pushing enough power to the ATV2. Once I connected power to the ATV2 it started working.
This also happened as I was trying to run the Seasonpass utility of my Macbook Air (laptop was plugged in as well).
So, I guess give it a try with the ATV2 power cord…
P.S. I used 1.5 iFaith and the latest Seasonpass
