as of Sept. 29th 2009 do not update your Wii. You will install System Menu 4.2 and this is dangerous for homebrew. Ive heard that a new 4.2 installer is currently being worked on but this is just rumors.
Tell everyone you know this will delete homebrew channel, update your boot2 v4, install stub IOS over cIOS. please do not update.
For now there is a new exploit using Lego Indiana Jones to hack your wii and install Homebrew channel. However not everything is still functional.
Version 4.2 of the System Menu was released on September 28, 2009.
[li]Deletes most homebrew.
[/li][li]Now uses IOS70. (No Preloader due to that)
[/li][li]Wii Shop Channel updated. Use WiiSCU to update the shop channel.
[/li][li]Most of the IOS’s have been updated or stubbed.
[/li][li]Updates your boot2 to boot2v4 (what LU64+'s have). (That means no downgrading of any IOS, and due to that, you can’t revert back to your old System Menu. So BootMii as boot2 installed is removed.)
[li]Bannerbomb - Doesn’t work.
[/li][li]BootMii - BootMii will cease to exist.
[/li][li]Homebrew Channel - It is uninstalled with this update.
[/li][li]cIOS - cIOS locations are stubed.
[/li][li]Preloader 0.29 - Not loaded any more due to IOS70 being used as the System Menu.
Wii Menu version 4.2 is now available for your Wii console. To update your Wii Menu to the latest version, please select the Update button at the bottom of the screen or select the System Update option in the Wii System Settings.
This update provides behind-the-scenes fixes that will not affect features but will improve the overall system performance.
Because unauthorized modifications to save data or program files may impair game play or the Wii console, updating to Wii Menu version 4.2 will also check for and automatically remove such save data or program files.
**Please note: If you’ve updated your Wii Menu after 9/29/09, you may not need to update again.
Thank you for updating your Wii console!
This is a solely anti homebrew update, it will delete anything and essentially everything to do with hacks.
I have uploaded this immediately so people can make sure their Wii is not updated. The update was released today.
Ok, here is more technical information:
What the update does is:
Install boot2v4 on your Wii. This makes any Wii like the new Wii with serial starting with LU64+. This is the first time boot2 has been included on a Wii system menu update, it means if you update, you can no longer downgrade to earlier firmware safely and do many things including bootmii as boot2. Watch out.
It deletes the Homebrew channel. This is huge.
It switches the system menu IOS to IOS70 and patches most IOS’s to fix vulnerabilities and so they can no longer run bugs, making Homebrew hard to install. There is a Lego game fix that can install Homebrew.
It installs stubs on IOS222, 223, 249, and 250, which are all custom IOS’s for running backup games or bootmii. This makes it almost impossible with the current tools to use USB Loaders, but later updates should easily get around this.
However, the patch on IOS250 doesn’t work very well, which means that it won’t patch over the cIOS if you have it.
Here’s the good news, Team Twiizers has released a new exploit for installing Homebrew. i will post the Indiana Pwns instructions and download link below.
