I have a New 3DS and I followed this guide to the latter and something has gone wrong. I was able to install FBI.cia, hblauncher_loader.cia and lumaupdater.cia from the Health and Safety/FBI menu. I opened Homebrew Launcher and updated Luma3DS from the main menu. My version now is sys 11.2.0-35E. I then put a .cia ROM on the root of my SD but when I inserted the card the FBI, Homebrew Launcher and LUMA3DS options were gone from my menu. I retried section v (Injecting FBI) and vi (Finalising Setup) of the guide but the same thing happened again when I added a .cia file to my SD. Now I have an even bigger problem where my 3DS says it cannot access my SD card and I think my NANDmin.bin may be corrupt (my backup didn't save to the cloud so I have none). I tried using Hourglass9 to restore from NANDmin.bin but it fails saying it's corrupt. The console still turns on but will not read the SD. I can boot in Hourglass9 and LUMA3DS menu on start up by holding start or select. Is there anything I can do? Can I restore to a lower firmware and begin the process from scratch?
