This app dumps the NAND to USB and SD. Before you can use USB 2.0 you have to install the "modded" version of the USB 2.0 cIOS (cIOS rev7 + USB 2.0), don't worry it, won't overwrite anything, it installs as IOS222.
Download: WiiND v2
To extract the dump you need your NAND AES KEY, you can get that by using the "Key Grabber" included it's xyzzy but it dumps nand-key.bin and common-key.bin to sd card. When you run the program there will be a nand-key .bin in the sd card (also a common-key but that's not necessary for unpacking but can be useful for other things ;))
Copy the nand-key.bin to c:keys (make the folder keys on your c drive if it doesn't exist) and then just run "extract.exe" and select the nand-dump.img file. It will copy the nand.img to the folder where extract.exe is and extract it!
