My wii almost completely stopped reading discs recently, as a possible solve I bought a wii lens cleaner kit from hong kong, which besides from removing a ton of yellowish looking gunk from the lens, had absolutely no effect on the usability of the drive. So I decided to try an official system update. The reasoning behind this was that I might have messed with some of the IOS since I downgraded from 3.4 to 3.2 previously and thought that an update might fix them (dont point out im a Noob, I know that already). My wii is hardmoded with a wiikey and softmoded with a backup loader (just for kicks) but no starfall, preloader etc. Im an impulsive person so I just went straight to the update option in wii settings and gave it the go ahead. Last I was on GBAtemp (been a lurker for a while) the newest system menu upgrade was 3.5 so that was what I was expecting. Low and behold my system menu went straight to 4.0. That made me turn on the old PC and have a browse around for info on 4.0.. Wiibrew stated that "Installing new homebrew is disabled by this version", so I got a bit of a sweathy palm syndrome right there.. Browsing GBAtemp I noticed a new thing popped up, a wii USBloader.. Now I was really kicking myself, because I read somewhere that I couldent downgrade from 4.0 and wasent able to install new homebrew, which I though the USB-loader would be. Finally here is the point of this rant.. I had absolutely no issue installing the USB loader or installing new homebrew.. It all works just as it did under 3.2 (havent tested the twilight hack, but I dont need that anymore).. I dont know if its because my wii is hardmoded or because I previously stuffed some cIOS in there. But it can still do it all.. Is the info at wiibrew wrong? Why are people using a custom install of 4.0 if the official upgrade method works fine? In short... What gives?
