    serial number is stored in a file at nand:rw/sys/SecureInfo_A (sometimes _B). it's signed. if you want it to work on a stock system, it must remain signed (so you can't come up with your own).

    Nintendo signs these, so no; use some cfw if you want to use an unsigned one.

    what are you trying to do with this?

    Anyone know if the serial number is stored in writable memory? If so it's changeable. Highly doubt this though. If it's in non writable memory then it's possible to spoof the ID in memory as the system boots cfw but that's the closest you'll get to a changed serial number.

    afaik changing it isn't enough for an unban though. I don't know all the steps, never looked into it

    In which case it is changeable but yeah I don't know the urban process either.

    On Luma you can also use SecureInfo_C instead, to avoid modifying the original file, and making it easy to revert the changes.
    You can unban at least partially. NNID login won't work along with anything that requires it, but everything else should. Try method 3 here: https://gbatemp.net/threads/all-3-methods-to-get-unbanned-from-recent-ban-wave.450679/
    You don't need to modify SecureInfo_A to play online, only to access eShop.
