But we agree that the Secure Enclave code CAN be updated, correct? I know that it can, because I remember an iOS update that fixed a problem with Touch ID on my iPhone 5s. If the DFU mode can't do it, then you just need to load an OS that will do it.
The only question is, does the existing firmware blank the store keys before flashing the new update. I didn't see any indication that it does.
