Hi All, Got forwarded to this forum by a friend of mine since he says you guys are the specialists . I just bought a Wii U from someone else who said he was using homebrew on it for playing the games and was running on v5.3.x. Now he cleaned the WiiU before he sold it to me and i think that in the process it got updated somehow since it now says 5.5.1 (E) which is the latest and greatest version. Now to make a start it would be nice to run from a SD/HD but not a pre since most Wii U games go on sale in my region anyway so i don't mind buying software once in a while. But the problem is that the game which came with it gives an errorcode 150-2031. After some investigation this seems to be a pretty common error so i thought this was the fault of the lens. After some more investigation (and since the fact i only got Nintendoland) I tried the following: - cleaning the disc (with whipe or alcohol) : result : Still errorcore. - Try to blow into the reader ( sometimes this helps....) : result : Still Errorcode. - Tried Wii games : these all seems to work without problems : result : Works!! - Tried a dvd movie (but not sure if it should be able to play them :S) : disc error. Is there any way or anyhow for me to check what might be wrong? I do have a bunch of codes from the error if that helps. Thanks in advance!
