Try mmcblkNX device.Hey, I'm looking to recover save data from a fully dead switch (I have all the keys etc. from the console). Am I understanding correctly that I should be able to use the SD card reader I currently have + the Low Voltage eMMC adapter to do a full NAND dump but the only issue is I won't be able to dump BOOT0 or BOOT1? That would be completely fine for me as I just need the USER partition.
Got a living dex on Pokemon Sword that I was pretty sad to lose (really shitty that they don't let you do cloud saves for Pokemon but I understand their reasoning even though I'm sure they could come up with some way to make sure it couldn't be abused to dupe pokemon) but if I can get the USER partition from the NAND that would be perfect.
