When I tried it with exfat support Choi didn‘t give me the FS-510 file for booting up the system via Hekate.
The second person here ;)

My problem was exfat support. First time I downgraded it with Choi (5.1 exfat) and then the switch still had a blackscreen. As I tried it without exfat support on fw 5.1 (because I read it here) .. everything worked fine.
Sorry for my english!
I used hekate and chosed "run OFW" option. When I choose CFW (atmosphere) then the boot logo appears but the screen stays black. I'm currently on 5.1.0
Could you please post the real one (command). I tried it and it didn't work...
auto
Solved!
