I search through the forum for an answer for this issue but didn't find anything.
I have a 5.2 atv2 i received yesterday, it came with stock 5.2 without jailbreak.
So i used the iFaith 1.5.5 do dump the shsh blobs, created a signed IPSW, jailbreak oficial fw with seasonpass, extracted the two imgs from the jailbroken ipsw and overwrited in the signed firmware with total comander, just like the tutorials i've always used for jailbreaking own firmware.
But now i Face the unknown problem (-1) when restoring in iTunes.
If i try to flash the signed ipsw it works perfecly, i don't know what is going on with this thing.
bad time to buy a new apple tv 2
I have another one coming, I hope it comes with older firmware or already jailbroken.
