A friend accidentally installed IOS58v6432 on his Japanese Wii U, but fortunately I have a NAND dump of a Japanese VWii, (dumped by using USB loader and in FS dump form), and here's what I decide to do: 1. Pack the wad with showmiiwads 2. Unpack the wad with Wii Cs tools 3. Replace the ticket with the real one and pack w/o Tricia signing. Are the steps practical?
