So you got your Apple TV and Jailbreak (Guide to Jailbreak Apple TV with Pwnage Tool) it’s time to save your Apple TV SHSH on file and set your jailbreak future safe. iPhone jailbreakers are more familiar with ECID, SHSH terms. For those who are new in the jailbreaking arena, ECID is a unique chip ID and will be different for every iDevice. When iTunes starts the restore process, they contact Apple servers to generate signatures just for your device. It’s important you get these signatures for your iPad before a new version of the software comes out.

Why i need ECID SHSH Dump ? Apple added a new piece of security called ECID, The nature of iPad / iPhone / iPod Touch / Apple TV hardware allows Apple to stop IPSWs from being usable unless you’ve already gotten the signed chunks they send to you based on your ECID (a unique chip ID). Actually Apple applies ECID so the iDevice will refuse to accept the ipsw file while downgrading because of a bad signature. It will treat it as a custom ipsw without having the apple server sign the ipsw specifically for your phone id before flashing.

Anyway, you can grab your ECID SHSH on file even when you are not jailbroken, and here is how to do it. Of course this will only be possible for the firmware version Apple still signs, which is (right now) 4.1

NOTE: it is very important to keep doing this for every firmware version that comes out after these!!
