I just bought a used Wii and it came on 4.1U, with all sorts of hacks installed like piracy channels, external dvd drive, and I could find all kinds of strange IOSes installed, like even Korean IOses. I used Dop Mii to get rid of what I could installing the original unpatched IOSes on top of modified ones. Then I tryed to UPDATE the Wii using normal means, but after like 2 minutes it gives the error 32007 telling me then to connect to a Wi-Fi network. Well... I could do everything using Dop Mii to Download from NUS perfectly! Ok so then I used DOP Mii to install System Menu 4.3U and that really removed Priiloader, then I tryed to make it update again to make sure no hack would be still there. No good, it gave the same error as before. Ok, then I went to Nintendo Shop to download Netflix... and like after 99%, after Mario jumps the last block like crazy, the Shop gives me an error telling me that the transaction had a problem and telling me to try to download later. I left IOS36 patched to try NandClean, but it oly gives me blackscreen! After all this stuff I found on the internet about that NAND Formatter, that gets rid of everything, and after using it I was at 4.1U again and used a Batman LEGO game to let it install the missing channels, since after NAND Formatter you only have the disc channel. After all this thing, my Wii CAN'T UPDATE, and Nintendo Shop can't download Netflix and Opera! But I could install YouTube!... Any ideas friends???
