    This is a complete dumping/backuping too. It allows you to dump the NANDs, OTP and SEEPROM, per your selection.

    This is the first tool to dump the SLC and SLCCMPT properly, including the ECC the spare data. Other tools are missing those parts, so they aren't proper backups, and can't be flashed back with hardmod. (But it can be fixed with the OTP and the tools that I released)

    This homebrew dumps those things to the root of the SD, so make sure to have enough free space for your selection.
    Options:
    Dump SLC (full and proper dump)
    Dump SLCCMPT (full and proper dump)
    Dump MLC
    Dump OTP
    Dump SEEPROM

    Big credit to @dimok. This tool is based on his Mocha CFW, seeprom2sd and otp2sd.

    SLC and SLCCMPT are both 512MB. so you need ~1GB to dump both. You can select which you want to dump.

    Gambia, The
    AFAIK (or remember one C3 conference) there is just 1 NAND, but divided in two (four) Pieces. One (two) for the WiiU and one (two) for the vWii.

    There are two NANDs, one is split in half for vWii and Wii U (512MB for each) and the other is the 8/32GB chip that is used for Wii U system and installed software.

    Nope, there are two internal memories:
    The eMMC NAND, for the friends MLC, of 8 or 32GB, with all the user data;
    The TSOP48 NAND, split in two partitions of 512MB: the SLC, with the wii u firmware, and the SLCMPT, with the vWii formware+internal memory.
    The MLC was already correctly dumpable with any rednand CFW, the SLC+SLCMPT not.

    So with this tool we can make a NAND backup and when the day come (or has already came?) those with a bricked Wii U will be able to restore it? Did I understand correctly?

    It's impossible to have a one file with all for now?

    Just one more question: do I have to backup something else or this tool does the entire job?

    This tool backups only the SLC and SLCMT, you need to backup the MLC and the OTP via rednand for 100% brick safety.
    Put please, this is still very WIP. Wait until tomorrow before use it on your console.

    Does it have a progess bar or something like that? Or does it seem like it is freezing but working in the background?
