I know it seems a repeated thread...but this is a bit more troublesome
I got a Japanese Wii 3 years ago. Haven't turn on and update the firmware for about 2 years. Yesterday I took it out (without wireless connection), put in a newest downloaded NHL2k10, the I forgot everything that I shouldn't update firmware from any game...and i did it. Yeah, they are all Japanese. I admit that I am so stupid! While the updating, I realized I shouldn't do that, so I quickly turned off the console. HOW STUPID I WAS!!!
Now, the Wii is semi-bricked. I couldn't go to the setting page. I downloaded Wii Fit Jap version, it does ask me to update the firmware, and I did that. This time successful, but still cannot open the setting page.
Treid the XXX-Jap-288-repad.iso disc, didn't work as the screen is showing some Japanese characters telling I properly unplug the power before while updating the firmware and ask me to refer to the user manual.
I guess no one is as stupid as I am...but hopefully someone can pelase enlighten me and guide me what should I do next to fix my Wii?
There is a way to convert systems to different regions. Do a google search for AnyRegionChanger. This can be dangerous if you don't know what your doing. So if you decide to do it make sure you learn before doing.
Could you explain me how you installed hombrew channel on Japanses wii?
I have the same problem , my wii is jap wii semi bricked by wii sports resort. I am having trouble installing homebrew channel.
