I have a old wii, it was chipped with a wiikey i think,
then a couple years ago i soft modded it, had usb drive working with it, happy days.
it then went into a box.
the older kids changed to xbox, now my younger ones are after the wii again.
also they want to watch netflix. so i need to update the channels.
then it wants a system upgrade which i presume is no go.
the system is saying 4.1E
What can i do to update the latest wii channels
Look at the "Softmod Any Wii" guide in my signature and go through it again. This will get you all of the updated cIOS files that were missing/updated since you last softmodded and will include how to update Wii Shop to the latest version (v21).
Once that is done, then you should be able to download Netflix from Wii Shop just fine.
