OK, I had created this thread about my semi-bricked vWii here. It seems that the source of my problems is a nand file stored in /title/00000001/00000002/data/cdb.vff and this file I need to manually delete it from my vWii. But I do not know any app that let me doing something like this. FSToolbox seems to only copy the files in the SD card. (correct me if I am wrorng) WiiExplorer while offers such an option for Wii,it seems that it cannot access fully vWii's nand yet. So,are there any other choices?
