I have a new-out-of-the-box ATV2, and I’ve done this so far:
used it a bit. It’s lovely!
Got the firmware (AppleTV2,1_4.3_8F305_Restore.ipsw ) from the LOVELY person who linked to it in their dropbox account.
restored that firmware via a normal itunes restore (which worked fine - yay, I have 4.3 now!) (apple’s servers are still stuffed for me)
Used Seas0npass to make a new IPSW (which worked). Flipped the ATV2 into DFW mode (again, worked fine), and then ituens poped up and it automated it to restore the created IPSW
this is where it all goes wrong. I either get a “not elegible” error, or error 21, neither of which I can find any info on how to fix.
I appear to have a single entry in my hosts file from seasonpass:
