i'm on the second part of the soft modding of the wii. i did "Install Bootmii as boot2 if you can". on my 4.0u wii, i installed cios bc boot2 was not an option. now i do not see the "launch bootmii" or screens as in the 2nd video. what do i do now to make a nand backup? i haven't done anything further.. waiting for advice.
