I'm on the 16 step of this A9LH guide - https://github.com/Plailect/Guide/wiki/Part-3-(RedNAND). When I press start I just get a black screen. I've waited for 4 minutes so I've shut my New 3DS down and tried to boot it up again. This time i just got only black screen with no configuration. When I press select at this black screen I can go to the configuration back. I'm using default 4GB card because my 32GB one is acting weird (I couldn't make a sysNAND backup on it, but it worked on the default one). I'm also using the newest dev version of Luma3DS. I've waited on this black screen for long time for the second time and still - nothing happened. What should I do now?
