This is more defensive approach to enable it for more platforms. The reason is the device is a production unit with secure boot enabled. Therefore I'm unable to provision again the device non-volatile storage. Also there are no EDL loaders available unlike on some other platforms so restoring the device is currently impossible. Even with the loader just physically desoldering the UFS BGA chip, then replacing it with a new programmed one with the dumped data and soldering it to the board it would probably not be possible to boot as the RPMB block would be missing the Authentication key only the manufacturer posses. I'd assume this issue might be already fixed on newer platforms. Would be great to compile a list of the platforms that definitely need this fix. Kind regards Petr
