> Is there no channel to re-key Secure Boot from an online source? There is no such method. Any such method would be potentially vulnerable if the device was jailbroken (from a purely software hack) - in which case, you would need some sort of permanent key to verify the re-keying which defeats the point. As a result, the Secure Boot key is burned into the chip and unchangeable.
