Hi @Mig
so far, I’m using the CustomROM [A]dvanced [XP]erience [OS] aka AXP.OS (A13) with VerifiedBoot and Relocking Bootloader on my OnePlus 6 (enchilada). Is this also possible with your iodéOS ROM?
I don’t think it would ever become “Official” (iodé wouldn’t add an “Officially supported” older device at this point as download server space limitations are already overwhelmed), and if they ever did they would use their own build process, but your “Unofficial” version can be posted here as is for the community!
