@developing_agent the internal dump as in, the one you dumped internally, is probably fine even if something did change. the firmware is writing EFI variables to itself. i doubt those will affect anything.

they only matter in the shut down context after flashing libreboot, since those vars no longer make sense and could corrupt libreboot if they're written like that, hence the documentation telling you to pull the plug.

i still recommend using the external flasher though, if you're wily enough
