I'm pretty sure the answer is no, but I wanted to check. A friend of mine sent in his 3DS for service and kept the SD card himself. He got back a new unit on a new NAND, so none of his SD content is recognized by the new system. Redownloading software is not an issue, but is there any homebrew or PC utility method to recover his previous saves? I've got a full Luma A9LH 3DS at my disposal to help, but all the methods I know to extract and restore saves require being on a NAND that is tied to those saves. Many thanks to anyone who knows anything worth knowing about this.
