    This is amazing! Good Job Dude im on 5.5.2 but am sure i have backed them up
    Edit: Correction i don't have seeprom.bin dump but i havent done a factory reset. Is there a seeprom.bin with these characteristics?

    Can it be used on GNU/Linux if I build it from source?
    I assume it can, since I managed to build it successfully.

    Yes, just copy the "data" folder from the zip, and use /dev/sdx

    I have not seeprom.bin backup, if I just use otp.bin to inject the haxchi can I brick the wiiu?
    Has anyone tested?

    It just won't work. But you can do hardmod and do the same thing to the MLC, because it only uses the otp.bin for the wfs encryption. But it is probably better to wait for new exploit...

    It is possible to extract otp and seeprom from emmc nand ?
    I had extracted the emmc nand with sd card reader hardmod.

    I don't understand. Do you have the otp of your console or not? If you do have, and you have sd card reader hardmod, you can just apply my tool on the mlc instead of the usb. (just don't specify the seeprom and use the --mlc flag). It is more risky than doing it for USB of course.

    If you don't have it - no it isn't possible to extract them from the nand.

    Thanks this is great, Excellent!

    For the confused replies to why you would want this. As I understand it, if you have your seeprom.bin and a otp.bin you can install Haxchi to a WiiU USB device from your PC.This means if you ever loose your softmod you can simply reinstall Haxchi with your PC even if you don't have an entry exploit for the sysNAND (like 5.5.2 which patches the browser).

    * seeprom.bin is unique to your WiiU no one can give you a replacement (I believe it changes in a small predictable way with each factory reset).
    * otp.bin al WiiU's share this same encryption key.

    @EyeKey Thanks you for the tools!! I have made a GUI for your file injector (simple but I think it works well). I posted a thread this morning .Check it if you want and tell me your opinion :)

    Could this mean a new (kinda) exploit for those on 5.5.2? i know your just quoting here (i have modded my vWii before i got updated) but i'm curious, if the pins could be accessed, could this help those who updated but have hacked vWii
