    I bought this new a couple of days ago and it arrived today, checked serial and based on it, assumptions was that it was "definitely patched".

    [​IMG]

    However I tried anyway and it worked.
    At first I thought this is a shell swap but it isn't. I matched the serial numbers with the serial numbers inside the OS against the shell's sticker.
    And interestingly enough, BIS Key generation isn't working properly, apparently according to SciresM my console needs a "fix" that he will help with in "~6 hours".

    [​IMG]

    This also means that it isnt a first revision unit due to it having revised BIS key generation.
    Because of this, as of right now I cannot safely use the switch as I cannot get a proper backup as the BIS keys currently gotten from Lockpick_RCM/biskeydump isn't working, it's entropy doesn't match the NAND.

    Pretty odd stuff.

    Update 29th Aug 2019:
    https://github.com/Atmosphere-NX/Atmosphere/commit/600d68bd1aa6f13b47b1482e48110b2e3c2684ed
    SciresM pushed a fix for BIS Key generation to Atmosphere-NX, and Shchmue pushed a fix to Lockpick.nro
    I confirmed they both work for BIS key generation on my unit. I managed to decrypt SYSTEM.bin, and mount it.

    After scraping through the SYSTEM.bin's NCA Headers, SciresM was able to confirm that there isn't anything of interest left behind on my unit.

    Update 18th Sep 2019:
    https://github.com/shchmue/Lockpick_RCM/releases/tag/v1.5.0
    Shchmue released a fix to the RCM version of Lockpick
    https://github.com/Atmosphere-NX/Atmosphere/releases/tag/0.9.4
    SciresM released a fix to Atmosphere CFW

    All that needs updating is rajkosto's biskeydump

    Im just showing this to notify people to not take serial number as face value on if your switch is patched or not, clearly it could be a case like mine, shell swap, e.t.c

    I wouldn't see why Nintendo would do that to be honest. It wouldn't make any sense from an anti-piracy perspective.

    This is absolutely remarkable to say the least. I would've never guessed that could be possible. I hope the opposite isn't though (i.e switch that's definitely supposed to be vulnerable but isn't)

    Possible that they forgot to apply the ipatches, or ran the wrong factory firmware?

    The OS prints the serial on PRODINFO. I will be interested in knowing whether the Device ID in eFuses matches the Device ID in PRODINFO.
    Feel free to DM me if you want me to calculate your BIS keys. This will require a FUSE+KFUSE dump for your console, though.

    At first I thought this was one of those "I got a patched switch, can I hack?" Threads.

    Can it actually boot CFW or is it unable to with what's available

    I would check that but I don't have BIS keys to read PRODINFO. Id rather wait for the fix from sciresm though.

    Takes like 2 seconds to try, so I said why not.

    So basically everyone with a patched switch needs to try it, and even buying a patched switch could be actually unpatched?

    Yeah it seems like they sometimes have old stock that are shipped with new serial numbers. Not the first report I've heard of this.
    Which edition Switch is it? Neon, gray, etc.

    Guys, chill out. Comparing Serials was never an accurate science. To make predictions, we need data, the less data we have the less good are the predictions.
    This is the reason why we can pretty accurately tell if a Switch is unpatched. Since this is a hacking community, people bought the unpatched Switches and
    the potential patched Switches stayed mostly in the shelf. Since we had to establish a boarder somewhere, the cutoff point to "patches" was more or less
    arbitrarily. It just means that where was never a Switch with this high of a firmware reported to be unpatched. Your find means that the boarders for potential
    unpatched units will be moved.

    That it doesn't support the BIS Key Generation is intersting however.
