Hacking How to restore a backup?

[Robertius]

Hello,

I have a R4 3DS/DS (r4ids.cn) and i think it is bricked (2DS XL does not recognize it since i tried to flash it through ntrboot, right?).
I have another R4iMax card for a nintendo DS, and a Nitendo DS as well. This one works fine.

How can i make a backup to restore R4IDS.cn card?

Thank you very much
