So your warrenty resets once you call it in? So if I get it repaired with like 1 month on it I'll get another one (refurb or whatever) with another 1 year warranty?
It was wierd for me. I updated everything to the latest version. But the first time i tried the card I got an error. I then reset the 3DS and tried it again and it worked.
Make sure you have the DSi Kernal 1.44 and Firmware 1.47 with the Caspian logo and you'll be fine.
Some people say it works on the new firmware and some say it doesn't. Everywhere I look people are giving conflicting information. I'm still on the launch 3DS firmware and would like to update to the new one. I don't have a NDS so I have to be careful.
My card's current firmware is 1.47. I'm on...
If you feel comfortable in doing the repair yourself, by all means try it. If you don't feel comfortable, sell it on eBay. You'll get a good amount still.
