Why would they have made the Secure Enclave allow updates on a locked device without wiping the key in the first place? Either they didn&#x27;t think it through, assumed they would never be compelled to use it as a backdoor, or perhaps they were afraid some bug could end up having catastrophic consequences of locking a billion people out of their phones with no way to fix it?  Do we even know for certain that the Secure Enclave on the 6s can be reflashed on a locked phone without wiping the key?
