Firmware

Page history last edited by haruspex 14 years, 4 months ago

 

Note: This page is about the Firmware on your Wii and upgrading/downgrading it.  For hacking any Wii, please refer to the Hack Your Wii guide.

 

Korean Wii Systems: Don't alter your firmware at this time.

 

Which Firmware is on my Wii?

 

On the channels page of your Wii, in the lower-left corner, is the Wii Options button.  Click on it.  Now click on Wii Settings.  You will be presented with the Wii System Settings 1 page.  In the upper-right corner is the current Wii Firmware you are running. 

 

Which Firmware is most recommended?

 

At the moment, 4.1 is the most recommended firmware.  The least recommended is 4.2, please don't use it.  4.2 did not add any positive capabilities to the system, only tactics for hindering homebrew (all of which have been bypassed at this point using methods described on the Hack Your Wii page).

 

Firmware 4.1 is the same as 4.0 with only one difference.  Firmware 4.1 includes a fix for a bug with Wii Sports Resort.  That's it.  There is no reason to be on 4.0 instead of 4.1.  The better choice is 4.1, hands down.

 

All firmware is fully hackable, with varying degrees of issues.  There is no need to remain on any firmware below 4.0.  If you are on a firmware below 4.0, then you are missing out on SDHC support and the ability to store games and channels and launch them from the SD(HC) card.

 

For more detailed information on the differences between firmware/System Menu versions, review the System Menu page on WiiBrew.

 

How do I upgrade/downgrade my Firmware to 4.1(J/U/E)?

 

It's super easy with dop-IOS MOD (although requires a WiFi connection).  This is included in the Wii Hacks Package.

 

If you have not yet installed the HomeBrew Channel, then you'll need to head over to the Hack Your Wii guide and learn how to hack your Wii. Once you are done with that guide, then come back here and follow the steps below to install the most recommended firmware 4.1 on your Wii system.

    2. Select your region
    3. Press A to select
    4. Press A to continue

Is there a method for Wii systems which aren't connected to WiFi?
