Is it possible to restore saves from SD cards with different firmware?

    So a few months ago I changed the SD card on my 3DS because of memory shortage and on the new SD card I updated the firmware. A few weeks later I realised my old SD would not be read on the 3DS for some reason, and I believe that reason is that the SD card has a different firmware version attached to it, thus the 3DS doesn't feel like reading it (I believe Nintendo was afraid somebody would find a way to exploit this, but people found other ways to do it anyway, good job Nintendo). Point is, can I backup my saves via a homebrew channel or something along those lines, so I can format the SD card and then download these saves? Or for that matter, anyway I can get my saves back?

    You need to provide which version you were on before and to which one did you update. IIRC firmware 7.x and above cannot read saves created on firmware below that due to differing encryption. Perhaps you can find a way to decrypt and re-encrypt the saves for your current firmware.

    You old data will become totally unreadable if you formatted the 3DS (it will use a different encryption on the files).
    but the SD card will still work fine, only you won't see your old games or saves.
