I recently followed the softmod any wii guide to update my wii because I had already installed HBC and BootMii via hackmii installer a few years ago and never updated since then. Everything went fine except my NAND back up. I also realized that I LOST my old NAND backup that I made previously. So I wanted to make a new one but when I tried to load BootMii my wii restarted. Everytime I try to load BootMii from HBC the menu pops up really quickly like a flash and then my wii reboots itself as if the program isnt working correctly. How do I make a new NAND backup?
