    Once you hit 'A' it will revert to the 'Wii U Menu' splash screen and then into the program. It shows the progress just like when it writes redNAND. Mine froze too at first when I use it with Mocha sysNAND but when I tried Haxchi sysNAND it worked.

    I assume a 32GB Wii U? What card are you using? Maybe try a different card. I remember it took a couple of hours for me (maybe more), so >24 hours is clearly wrong.

    please rework fat32 check, many users have issues with the current way.

    On my 16GB 64k cluster status is "Invalid paritition status" and after a proper reformat with guiformat its "first partition not fat32" but there is just one... I also rebuild MBR

    I need to see an example of such format, can you send me the first few KBs of your SD? (Of the raw data)

    Sorry I can't anymore the old SD is reflashed already. Just bought another SD (MicroSD SanDisk Ultra 32GB Class 10 A1) and its working now :)

    Maybe some cards just dont like the check. I hope @ceevee can provide his dump.

    I sent the first few KBs of a raw data copy. I'm not sure if I did it correctly.

    Thanks for that, but that is the start of the FAT32, I need the MBR.
    One simple way is to download hex workshop, and use "Open Drive", select the USB, and than "Save As..". It should be 512 bytes.

    So is there any way using software/homebrew with CFW to write the NAND back into the Wii U without resorting to a hardware mod? Are there any technical limitations standing in our way?

    Is this just a raw encrypted dump, or is the dump decrypted on the SD card?

    Update: I had trouble (i.e. "first partition not being fat32") with the Samsung EVO 64 GB card. No error with the SanDisk 128 GB Switch card.

    Why can't we write the NAND back to the Wii U? We can on the Wii, and we have all the permissions we need on the Wii U to do so. Nobody can ever explain the WHY, they just reply with the useless "You need hardmod" response, not caring to explain the technical limitation(s) standing in the way of NAND R/W on Wii U.

    Feel free to implement it. But it is risky and useless. If your NAND filesystem is functioning, I don't see any reason to overwrite it and having a chance to brick it.

    i have a semi borked nand wiiu (wiiu bootloop) - oddly haxchi is still loading elf files, even more weirder is i don't have cbch installed,

    anyway, i replaced the hbl elf file with that of mocha, mocha logo will show but will still result on bootloop
    nand dumper boots when i replaced the elf file of hbl with nand dumper.

    hence the question, if i could write it back. I know this is a lazy excuse to totally avoid hardmod, i'm totally comfortable with it. it's just that, the write feature is usually available with the dump tools
