Here goes: I bought a 3DS on launch day. I popped in Ghose Recon and started playing. Five minutes later, the screen just goes black with white text saying "There's been an error, please power down now". I do that, and five minutes later, same thing. So I go to another game in try out Steel Driver. Same problem. I lived with it for a few weeks because I just got the system and didn't want to part with it. Everything else worked fine, including streetpass. Even got a few tags. Finally though I got fed up and sent it to nintendo. Three weeks later my system finally arrives back. Pop in Ghost Recon and played for several hours with no problem. Tested another game, no error message. All seemed well. Then I went into the Mii Plaza to go play Puzzle Quest and use some of the coins I'd accumulated. It said I had to activate streetpass, which I had assumed was already on because I never deactivated it. So I go back to the Mii Plaza and turn it on. It said "Saving..." and then froze. I powered off and tried again. Same problem. I even let it sit for almost half hour hoping it'd unfreeze to no avail. So I call Nintendo back aid WTF. They couldn't figure it out so I was given two option. I could do an advance replacement, pay five bucks, get a new system, and send the defective system back at my convenience. Problem is I have things saved in system memory that can't be transferred to SD card like streetpass tags I didn't want to lose. They also they can't transfer my account to a new 3DS (they cite policy, not technical reasons), so I'd have to pay AGAIN for what already bought. So I choose option two and send in my system again. Three more weeks later and I just get it back. The first thing I do is go to the Mii Plaza and fire up Puzzle Quest. And again, my streetpass was off. So I go to turn it on and the damn thing FREEZES YET AGAIN! Furious, I get Nintendo on the phone, get passed off to the technical department, and the rep couldn't figure it out. He said to me they had no records of this problem in their repair logs. Considering the hundreds of thousands that have been sold in the US, I find it extremely difficult to believe I'm they don't have a single record of another occurance on file. Trying to think outside the box, I thought maybe the memory card could be the problem since Nintendo requires you not send that or the stylus when you go do a return. I copied all the data files from my original SD card, transferred it all to my PC, formatted the new card, and then put the files on. I got back to activate streetpass and it freezes. The only other thing I could think of was to try to activate it through a game, so I put in Super Street Fighter. You can activate streetpass there in the options. I go to do that and surprise...it froze. I've had three different 3DS systems now (according to one of Nintendo's reps, they have three serial numbers on file. My original worked fine. The only thing I can think of is maybe it's a file on the SD card that's causing this. I'm on the latest firmware. I've never put a flash card in there. I've never messed with the battery. I'm at a comple loss. I'm absolutely stunned a company would send back a repair, say it was fixed, and have the exact same issue pop up. Don't they test these things before they say it's good? Any ideas? I'm open to any suggestions and figure you guys probably would be ahead of Nintendo anyways. They seem clueless about their own hardware. Thanks in adavance.
