Hacking Help Updating R4i rts 3ds

[izilchy]

I got this card for a dsi and it works perfectly. Its a R4i rts 3ds card revision C bought from r4ids.cn . I tried going to the website and downloaded the new firmware from the website and attempted to update on the dsi(because the 3ds is already 6.2.0-12u) but when updating i get an error "card check filed" and it never goes away. Im going crazy trying to update this card if it is even possible lol please help
