I followed 3ds.guide a while back and upgraded to Luma3DS v7.1. If I remember correctly, I installed Luma3DS into CTRNAND following this guide. Now, I am trying to follow the guide to upgrade to v8.1 and placed all the payloads into /luma/payloads on the SD card, but chainloader menu doesn't show up when I press & hold START button during power up. My guess is, Luma3DS is checking payloads folder in CTRNAND and not SD card during load and finds nothing to load. How do I make it find payloads and display chainloader?
