[Yousef.AlMal]

Hey guys i have a problem of downgrading my apple tv 2g i was on 4.1 then i tried jailbreaking it but it didnt work so i update it to 4.2.1 and when i want to jailbreak it on 4.2.1 itunes error ''21'' says that i cant restore my custom build ipsw from pwnage tool. So can you tell me how to fix this ''21'' error or downgrading to 4.1 because i knew the way to jailbreak in 4.1


Thanks
