Hacking Change Wii Region forever

[OldClassicGamer]

Hello, I have Wii 4.3E and I would like to change system menu to 4.3J
I used AnyRegionChager but because my system menu is not matching when I change everything else, I get Semi-Bricked Wii. I can of course restore it back and it wont be semi bricked anymore. But What I want to do is change Wii region from 4.3E to 4.3J forever so it is my main system menu. How can I do it?
Also a question, if this can be done, can I later change back system menu to 4.3E? Just asking.
