Could this allow bootloader unlocking, custom roms, etc. on an otherwise locked device (e.g. S7)? Tried the engineering bootloader, but horrible battery management.
I guess it depends which public key the device is willing to accept updates from. This exploit gets you the per-device keystore private key, which is not going to be being used by vendors to sign builds. But perhaps there's an option somewhere to allow running firmware updates if the payload is signed by the device's keystore key, I don't know.
