hi there, I've been thinking. If you use NUS1.1 to download the WADs necessary to upgrade to 4.0, and these WADs are official, non-hacked. like IOS60. Can it be possible to install System Menu 4.0 from a LU64+ Wii with 3.4FW?? If I don't use Hacked IOS nor lower version IOS, it should be fine.......right??? Any input is welcome.
