    Welcome to the CBHC hardmod unbrick guide. This is not for the "faint of heart". In other words, this is not a noob guide. I expect you to have skills in micro-soldering as well as a basic knowledge of windows file system. I will not hold your hand through every step. This guide is for IT professionals with micro-soldering skills. If you do not fit these qualifications then hire someone who does. I will not be held responsible if you permanently disable your Wii U. This guide is for users that inadvertently bricked by messing up CBHC. I know that you can use the same steps to fix other nand issues but I won't be covering that here.

    This guide assumes that you at least have a nand backup. This includes but is not limited to "otp.bin" and/or "slc.bin". Please read below for more information on what you actually need to make this work.

    Just make sure you already have nand backups!

    Thanks Jax. Took me long enough. Permanantly bricked one Teensy++ 2.0, one Wii U, and 3 voltage regulators figuring this out.

    Can't wait for the first reported CBHC brick fix using this guide (other than my own)

    Kinda it's impossible to read red text since it burns into my monitor but this guide is pretty good.
    Nice work as always, Kafluke.

    I appreciate all the efforts and the (hardware) sacrifices that went into this. Great job! And all this for the tiny less than 1% of users who couldn't follow instructions and warnings when they installed CBHC. You're a saint, Kafluke.

    This was a quick compile before I left town. I know the text and format sucks. I just wanted to get all the info that I had compiled posted for those that have been waiting.

    If anyone feels up for the challenge and would like to pretty up the guide please let me know and I'll make you an editor. I could use some help in that department. I'm not a designer.

    I'm getting 'Failed to determine dump type'
    "Error setting path to nand object"
    I have otp.bin in the same folder
    My slc.bin dump size is 2162688KB
    What could be wrong?

    @Kafluke , what's the size of the your mlc and is it needed really? my mlc is one gigabyte smaller than the one you mention in your tutorials. it's 29.1GBs instead of 30.1GBs. was/is that a typo?

    @Anonyamalious How did you get the slc.bin dump? was it from the hardmod dump or from the WiiU NAND Dumper software?

    The slc.bin (WiiU NAND) should be 528MB (540,672KB)
    The slccmpt.bin (vWii NAND) should be 528MB (540,672KB)
    The mlc.bin (Storage NAND) should be 29.7GB (31,162,368KB) (Toshiba eMMC chip inside) or 29.1.GB for the Samsung eMMC chip inside.

    hmm. ours is different from @Leeful 's though. I'm backing up my mlc using eyekey's app. I originally backed up everything with the fw.img. I thought the mlc was safe, so I fixed my slc and slcmpt with @EyeKey 's tools, then redumped them with eyekey's tools. I want to make sure my NAND dumps r complete. I haven't bricked or anything (on cbhc), but I want to have everything I need if that does happen one day.

    edit: btw, how do u merge these mlc files?
