Hi, great article, a good help.

It would be great if you have any advice on how to solve my current 3DS transfer nightmare which I am experiencing right now. It is quite complex, but i’ll try my best to explain it.

So, I had a standard 3DS, and have had it for 4 years nearly. Lots of data; Streetpasses, Friends lists, Downloadable games and saved data was stored on it with an 8GB SDHC card.

I was invited to the New 3DS Ambassador program, and subsequently purchased one. I done a system transfer from my OLD 3ds to my NEW one. (So from the 8GB Standard SDHC to the Micro 4GB SDHC). At first some of the data was missing, but, I followed your step 1 tutorial and managed to get all of my data onto an 8GB Micro SD which I had spare. So everything was working. I then backed up ALL of the data onto my PC.

I started to have trouble with the 3D effect on my NEW 3DS and, it turns out it was faulty. So I had to send it back for replacement. And I requested them to transfer everything over to my new, new 3ds. However, they ignored my request and gave me a refund instead. They did however, unlink my NNID.

So, I then purchased a New, New 3ds and linked my NNID to it. I then expected to be able to recover my old files which I had backed up on my PC by copying them back to my SD card. But, nothing seemed to show up on my New New 3DS.

My 3DS shows that there is something on there because some blocks are being used, but it will not show or read the data. I fiddled about with the files to try to fix the issue and at one point it showed the data but was all corrupted… I don’t think the source data itself it corrupted because it all shows on the computer fine, but I believe it could be that the New 3DS is having trouble recognising the data on the SD card because of the file arrangement.

When I load the folder on my PC, it shows 2 gibberish files above the one which says private. The first one has one file inside it and the other has 2.

Any help at all would be amazing! 4 Years worth of data is on the line!!! 🙁
