Apple TV 2 Stuck at 4.4.2 can't jailbreak

I have a new atv2 that is in 4.4.2 I have the shsh blobs saved, the problem is that snowbreeze won’t jailbreak this version, and the total commander method with season pass is not working for me, after restoring the modified ipsw with presigned keys i get a black screen when booting.


is there any chance to get unthetered (I really need this) in my case?

Only by buying one already done unless you have the blobs saved for an untethered version.
