It is true that modding a wii can be quite risky, specially if you dont follow the right procedures!
But that is not the case here. I have modded about 20 wii's and still keep in touch with every owner to check if they are experiencing any problems with their modded wii.

The other point you made was that you have a bricked wii, my guess by from what you wrote on your post is that you had your wii modded on a certain version and then tried to update through nintendo. This would have not happened if i had modded your wii as i always make sure to be on the latest version so that you dont have to avoid any updates or that by accident you update your wii.

There is no use in keeping your wii on a old software version as everything you could do on a 3.2 system you can do on a 4.2 system now which is the latest version...

As you see I'm not someone who doesnt know what he is doing. I hvae been doing this for months now and have modded several wii's including my own which works flawlessly.

I might be able to help with your bricked wii, if you give me some information about what firmware version it was, softmodded or chipped, how it got bricked, etc i might be able to find a solution for it as there are many ways to unbrick a wii.

Regards

Edit: All of the respective owners from the wii's I have modded are yet to experience any kind of problems with their wii's due to the modding. In fact they are all glad that they modded their wii as now they do not have to worry about pal or ntsc games
