I've been working on this issue for nearly two weeks now. It's a holiday weekend, so I'll probably end up calling Nintendo (for the fourth time) tomorrow, but I thought maybe someone here would have a quick yes/no answer.
I bought a new 3DS XL, and gave my old 3DS to a friend. I only saved the SD card, and at the time, I didn't know about the system transfer. I wiped the old 3DS before giving it to my friend.
When my SD card didn't work, I called Nintendo and they said they could transfer the data using the two systems' serial numbers.
I got an email saying that my problem had been resolved, but nothing seemed different on my 3DS XL. I was under the impression that all my Street Pass data and games would come back after the transfer.
I can redownload the digital games I had previously purchased from the e-shop (which is a start), but is there a way to get my old saves and Street Pass data back from the SD card?
