I used to have an R4 for more than 2 years and I never had any problems with it untill my cousin broke it so I bought a new one. I've tried and done everything I've done for my old R4 but when I open my ds it just goes *LOADING* and even if I leave it for an hour it still wont work. I don't know what's wrong with it. I also knew how to put pictures and music in my old R4 but I don't know what I've done wrong with my new one. *My R4 isn't fake* I've also just bought an 8GB micro sd card but the biggest sd card I've ever had was a 2GB micro sd card.
Is that the problem?
Does anyone know why my R4 is not opening?

Thans in advance.
