Tried the twilight hack but it failed? Yeah that exploit was fixed in 4.0
This guide will allow you to install homebrew channel and downgrade to 3.2 to get rid of all of nintendos hack blocking, then return to a modified unlocked system menu 4.0.
From there you can do everything, run back ups, load from usb, play dvds etc.
This is only for North American and European wii's ONLY!!!
This will not work on korean or japanese wii's This will not work on your Wii if its serial number starts with LU64 or LU65 or anything higher
I must state that you are following this instrucatable of your own violation, there is always the possibility of bricking your Wii. I take no responsibility for your actions and do not encourage piracy if/when these features in your Wii are activated.
