The system refuses activating them by popping a window to let me confirm the 3DS user agreement. But it has already confirmed. Anyone has an idea? What I can do right now is to GIVE UP activating them or buy a US-region console with FW 4.x. BTW, it's fine to activate JP and EU games' Spot/StreetPass on non-local-region hacked 3DS consoles because JP and EU games don't require us to confirm the 3DS user agreement.
