Hacking Need help with my R4 Card

[Zanranon]

I think I found the software for this card but I get an Error Code.. and i think its because of my Software (I got a Nintendo DSi 1.4.5E)
But I think I used this card even with this firmware 2-4 years ago... (I lost every data of the R4 Card)
So I need help...
If its really because of the Firmware.. how can I downgrade my Nintendo?
but if its because of the Softward for the R4 where can I get an updated Software ?
And no I can't update the R4 card from another Ds because I don't have one

What is the error that you get? I have a r4 from the same website, I may be able to help. They are all very similar
