[Destiny2016]

hi everyone im new here and im hoping someone can help me
im not very clued up about these cards so please forgive my blonde bimbo comments lol ,

i bought a R4 3DS Card from someone (im from the UK)
I put it in my DSI but it didnt work and i bought a 3DS and it says the same thing

there is a gold picture with a sword going through it and it says "Deep Labyrinth Digital Bros"
and when i click it , it says the same error message "An Error has occurred please press and hold the power button to turn the system off"

i took the memory card out and tried a different one to see if its the memory card but its not it says the same thing here is the picture of my r4 card

Are you using CFW?

What files do you have on the micro sd card for the r4 card?
