I followed this guide
from the start to the bit where it says The following are really optional and not needed to play backups. Also mind that incorrect use of them might brick you!! so use with caution!!
using all of the first downloads but when i try to change the view of the HDD (Carousal or Grid) or change the settings then the wii starts to do a stack dump.

I have tried restoring it with the NAND and starting again but it still does the same thing.

Please help me as i have no idea what has happened. Do i need to continue on with the tutorial for these to work? or is there somthing else i need to do? or should i try one of the other downloads?

Please Help
