BLOCKED Save game transfer

If your Switch is modded as well, you could back up the saves you're trying to transfer with homebrew such as EdiZon or Checkpoint and just transfer the files via PC then restore them on your Switch with said homebrew.

 

After transferring if you have the Nintendo Online subscription you may back up your saves via cloud before factory restoring although it would be unnecessary to factory restore if you just remove the files to mod the switch from the SD card.

 

if its a new console, modding is likely not an option at this time.

and even then, just modding it can lead to a ban unless you set up emunand and are careful with it.

I'd guess how dangerous a save transfer ends up being depends on the game. anything that phones home in some way might be a risk, online games like splatoon and smash more so than others. honestly, it's really not worth it.

 

You should be fine as long as you're not modifying your saves to use online that gives you advantages over others.

 

Factory restore would have no effect to your nand. If you want to be really safe then I suggest looking up installing emunand
