Hi all,
I'm new to wii hacking, so please be gentle.

I have just got a pre-hacked wii from Thailand. After a bad experience with my old wii, I thought the first thin I should do is get a NAND backup of this one.
I tried the hackmii installer and get the no vulnerable IOS message. I've read this could be because a hack pack has been installed.

The thing is, I've got no idea what kind of hack is on the wii, so I want to be REALLY careful about what I do to it.

Anyone have any suggestions of how to go about identifying what is on it so that I can get my wii backed up.

It is running 4.1U and hass homebrew 1.01 USB Loader GX uLoader and a few other channels on it, if that helps.
