Hello everyone. I was using 3ds guide to install the luma CFW in an old 3ds xl version 11.2. Anyways I got to the step where I needed to configure luma and scroll down and activate "Autoboot SysNAND" "Use SysNANF FIRM if booting with R" and "Show NAND or user string in System Settings". I pressed start and got the black screen. Now that's all I get, if I take out the SD card the 3ds will shut off right away and if I keep it in the 3ds stays in a black screen. What's the problem and what can I do?
