    Just fyi, I confirmed this observation a long time ago by looking into the IOSU code. Actually the whole seeprom usb seed acts as one big number. Meaning if the last byte runs over you have to increment the byte before it by one and so on (just like any normal integer incrementation in big endian). There is even a "bug" in nintendos code where the first 4 bytes would also increment, if the number ever gets that big (which I doubt). I can give you guys the IOS MCP position of the function, if you want to patch it to stop doing that, I would need to look it up though.

    Sorry for the noob question, I have a 5.5.2 wii u and I'm going to get one of the lego games for vWii. Can I backup seeprom from the vwii mode?

    Read what he wrote. He talking about how the Wii U adjusts it's seed for usb encryption. You can't guess it if you don't know what value it started from and an old post says we can't read it from the vWii, however he knows the address to patch out the seed changing meaning you could format and still use your usb drives without formatting them.

    Hello,
    i hope someone here can help me.
    I have formatted my wiiu but not formatted my old hdd that has my wii u games and saves.
    now I want to make it work again as it is not recognized by the wii u anymore
    I have downloaded seeprom.bin and otp files.
    I will change the values for usb key seeds but I want to make sure they are the right ones.

    so should I decrease this 1 value to A4?
    and after that how can I make use of this file? should I use mocha cfw? can someone guide me through?

    Running the command
    Code:
    Get-WmiObject Win32_DiskDrive
    yields the error:

    You should clarify this part or provide an alternative.

    That looks suspiciously like you're trying to issue powershell commands in to the Windows Run command box.. You need to use powershell.

    Of course not, stop asking people. How hard is it to understand you need the NAND dump in advance?

    A bug that was already fixed in wfslib, but I haven't update this program yet. I will update it today.

    If you're in a hurry, I compiled this like 2 days ago so it has the error fixed.
