The correct IOS and IOS revision (this is very important) for that System Menu.The System Menu version you wish to downgrade to.BootMii NAND Backup (not required but highly recommended)īefore you start, you need to know a few things:.An SD card, and a way to transfer files to it.A softmodded Wii ( make sure that if you have a custom theme installed, you restore the default theme).A Windows computer with internet access.In order to downgrade, you’ll need the following things to start: This creates an extra step when downgrading, as the stubbed IOS must be unstubbed. For example, IOS70 was stubbed out with the 4.3 update. When Nintendo updates the System Menu, they also stub out (meaning making it useless) the previous System Menu IOS. The main exception to this rule is System Menu 4.0 and 4.1, which both use IOS60. It’s not too often that the same System Menu IOS is used for multiple System Menu versions. For example, the latest System Menu version is 4.3, and it uses IOS80. The System Menu has two major parts: the System Menu itself, and the corresponding IOS. If you don’t understand it, you probably shouldn’t be trying this.Īnother thing to note is that if you have a Wii that is incompatible with BootMii as boot2, and you are trying this anyway, absolutely do not downgrade below 3.2. There are parts of this guide that will not go fully into detail, acting as a safety check. Otherwise, you could cause a permanent brick (only fixable with a hardware NAND programmer!).

It’s highly recommended that you only try this if you have BootMii installed as boot2. WARNING: Downgrading your Wii is highly risky and not very useful.

I don’t know why you’d want to downgrade your Wii, but alas, here you are.
