GrapheneOS@lispi314 @maumau @fluffery @kkarhan @BryanGreyson It's not possible to externally improve most of it on a whether or not it's open due to verified boot and signature checks. On a reasonably secure device, the only way you can do that is if there are device variants sold where efuses are not yet burned and you can burn your own signing keys into them or use it in development mode without those security checks, which wouldn't be something we would do on a production device.
