Recently bought a pre modded 3ds from JayBoyModz. Im trying to use Pokémon Bank to transfer my living dex to my Switch, but the app keeps throwing the 005 5859 error at me. The 3ds is JP to US, and I've tried the Luma Locale Switcher to try and resolve the error. Is there any other fixes that I can try to get the app up and running?

Thanks in advance!
