Yes there is an md5 file and the check does pass on those wads on my SD card. The check finishes without any error.
I'm doing a new nand.bin backup right now. I shall come back with the nandbincheck soon.
Edit: Also, now I can't access my Wii Menu. I think it's because I tried to uninstall it (that's when it froze at 3/9).
I was thinking about following the "Softmod ANY Wii" guide once more.
I tried the nandbincheck with an old backup I had and it give me a bunch of information.
Now, I did it with the recent backup I made and it stopped and gave me this message: "One of the shared contents in this nand is missing".
See for yourself:

Edit: I searched on Google and only got a few results. One thread on WiiBrew and another one on GBATemp but it does not help much (by the way, you posted on both threads). I also found the code for nandBinCheck.
Perhaps it's time to use that old nand.bin backup and "restore" my Wii? Unless you know it's not going to fix it and/or you still want to work with this broken Wii just for the sake of knowledge and future reference.
