Hello, I am a new in this community. Nice to meet you everyone. I'm pretty noob about Wii U hacks so you guys might heard this question a lot but please help me. I have Wii U with 5.5.1 U firmware + RedNAND Mocha CFW and I like to change the system region to Japanese. First I thought I can switch through using SysConfig Tool in RedNAND but it didn't work. I've tried to edit sys_prod.xml file but it just bricks the System. Is there any way to install Japanese firmware on US console? (Something similar with using CTRNAND Transfer on 3DS). If I get fw.img from Japanese system, will it switch to Japanese if I install RedNAND again? I know it is region-free since I've got Mocha CFW, I wish I can have this option. Thanks.
