A couple months ago my brother spilled some water on my 3DS. I immediately tried to dry it with a towel and blowdryer. It was acting strange for a bit but after it dried it was working fine. So I figured it was fine and didn't have any problems up until a couple weeks ago when it stopped charging and wouldn't go past the home menu. So I sent it in for repair and they said it wasn't covered under warranty due to water damage. Cost me ~$100 to repair. When I got it back I started it up and it was going through the initial setup; then I saw a note that they replaced my system which they didn't tell me they were going to do. I noticed that my games from the ambassador program were there, but when I went to streetpass mii plaza it said I didn't have a default mii and to make one in mii maker. The weird thing is when I highlighted the mii maker it showed all the other miis that I had previously. I called nintendo and the lady I talked to wasn't very helpful, she basically said "yeah that can happen". But when I was making the repair order it didn't say anything about streetpass data being possibly lost, it only mentioned stuff like photos and internet settings being lost. I had almost 1000 unique miis from various countries, all the puzzle pieces, and almost all the hats. I put a lot of time and effort into streetpass so I want to do everything possible to get it back. I've been trying to find some in depth info about how streetpass works and where the various data is stored. Any info or help is appreciated!
