I have a Black ATV with 4.2.1 installed and jailbroken. I understand that this is a tethered boot, no problem. I have not tried aTV Flash yet, just seas0npass, as well as doing it the pwnage way.
The problem I am looking at is that the only machine anywhere close to the TV that I am setting this up on is a G4 Mac Mini. I have tried booting it using thetherboot from a "tether" fodler on my desktop, at first the universal binary woudln't work, so I recompiled it and got it to get at least partway through.
Is there any solution for tethering this thing to a non-intel mac for the boot? It's either that or I have to haul an iMac into the living room just to boot
