I temporarily uninstalled CBHC and temporarily reinstalled Haxchi so I could fully dump a proper NAND (OTP, MLC, SEEPROM, etc.) in case I bricked and had to use a hardware mod to unbrick it. I used Wii U NAND Tools and apparently the tool dumps the MLC in 15 parts in the format mlc.bin.partXX. How do merge the files into one? Because I'm pretty sure to restore a bricked Wii U it has to be merged into one mlc.bin.
