I bought a second hand refurb Wii with a low serial number from ebay LU37... As soon as I got it I called Nindy to ensure that it wasn't Hot or a gray market item. Nintendo's response was puzzling. Me: Hi nintendo? I would this Wii and want to make sure it's a "valid" console... Serial number: LU37..... CSR: I'm showing that serial number, but not as a retail unit. Me: Is it stolen, should I call the cops and get a refund? CSR: Hold on... let me get my supervisor. Super: That serial number is no longer under warranty but there are no recalls or defects with your specific unit. Me: So it's a legal sale and I can keep the unit. Super: Yes, the console is a valid serial number. Me: thanks. OK.. so I'm guessing from their response that either this unit was a rebuild, a re-case, or refurbished. So... how do I get the "real" serial number. The one on the case is the "case" serial number, but I suspect the NAND has the serial number stored somewhere as well. Q: Is there a location in NAND, or some homebrew app, or system menu navigation that will tell me what the Wii "thinks" it's serial number is? Thanks.
