http://www.yafaze.com/wii/tutorials.html NO LONGER ANSWERING QUESTIONS.........sorry UPDATES GUIDE is now V4 (cleaned up and added more details and a big CIOS + HBC warning to save people making mistakes) IOS60 workaround for those that get stuck installing 15/15 files need to find a patched IOS60 wad and install via Wad Manager. NOTE: If you still have trucha (IOS60patched) installed and a modchip and you lose the Homebrew channel use THIS to install it again on 4.0 (Thanks to Davi92 for the edited HBC iso) NOTE2: Because the Wii will run games from SD doesn't mean it avoids the risk of banner bricks, the wii still loads the games into memory before running them. A note on trucha after updating If you want Trucha back after installing 4.0 using the Direct Nintendo update use Waninkoko's IOSDowngrader (not CIOS Downgrader) or use Gecko OS as that works 100% tested. Custom guitar Hero will require a IOSdowngrader run. I haven't had any problems with any VC games (SSB is said to be a problem but 100% works here), just make sure they are for your region machine. If you need help or don't know what something is in the guide DO NOT UPDATE ask around first.
