Hello. So I downloaded the latest form of luma for 11.15 firmware. However, NTR CFW is now not working. It says on a black screen "crash dump: save files?" and shuts down the 3ds when I try to open it. I don't know what to do. Do I need a custom form of luma 11.15 to do it correct? How do I get that custom form,if needed, for 11.15 firmware?
