Media Files in Pre-JB Apple TV 2 Cache


When Seas0nPass creates the custom .IPSW when jailbreaking an ATV2, does it draw from the current, un-broken system in order to somehow be able to keep media items that are actually stored on the ATV, such as the screensaver photos? Or does jailbreaking with Seas0n Pass completely wipe the contents of the pre-JB system? If the latter is case, is there anyway to hack/JB and not effect the existing media file directory. This is the reason I am looking to JB in the first place…to be able to SSH in to the ATV and access the photos that are utilized in making the photo screensaver/backgrounds. Thanks.
