In updating to luma3ds 8.0, i had to update b9s as well. After doing that, i replaced the boot.firm, and rebooted. Even though i downloaded the latest version of luma and put the newest boot.firm on the root of my sd card, it still throws the error "Unsupported launcher (argc = 0)", which is supposed to happen when using an outdated version of luma with the newest b9s. This same error happened when i updated b9s before updating luma so i know the update was successful. What could i be doing wrong?
