Hello, Here's my strange situation. Originally, I had EmuNand and attempted to unlink the NANDs via Tiny Format. The app never gave me the option to select which NAND was formatted so I believe both of them were. Since then, I've re-installed EmuNand (I am using ReiNand CFW) and now for some reason I have two seperate folders in my Nintendo 3DS folder, even though the two NANDs are still linked. Ever since re-installing this new EmuNAND, I am no longer able to install cia files. I get this error: Install Failed! HBL.cia Source: SOURCE_FSFILE_WRITE (0x1c) Module: MODULE_NN_AM (0x20) Level: LEVEL_PERMANENT (0x1b) Summary: SUMMARY_INVALID_ARGUMENT (0x7) Description: DESCRIPTION_INVALID_SIGNATURE (0x6a) Press Start to Continue. This happens when attempting any cia file that previously installed with no issues. What should I do?
