try using only the boot flag alcid= and add the id you are testing to it like alcid=12 remove any alcid's you have in ssdt's or property injections in config. with OC you will need working nvram if not it will not update your alc id as you test different ones. you will have to manually delete the variable from nvram and enter a new nvram value.
