i just bought a wii from the internet and its a 2006 model and it has 3.3u, should i upgrade to 4.2u and mod it from there, or 4.1u or leave it as is and mod it form 3.3u
Just follow any wii hacking guide by Mauifrog step by step - you will find there part "Downgrade to/Upgrade to/Install System Menu v4.1". It's optional, but Recommended!!
Do not forget to follow part with IOS update and shop channel update (Chapter 2).
