sorry if I have been posting lots of threads. So I tried having a CFW sysnand because I have a9lh+luma3ds emunand and they said it's much better . So what I did was to follow this from Plailect's guide
- Reboot, then open Decrypt9 from arm9loaderhax by holding Start on boot
- Go to "SysNAND Options"
- Go to "SysNAND Backup/Restore..."
- Select "NAND Restore (keep a9lh)"
- Confirm and restore from emuNAND_original.bin
