Ok so first I checked what was done with it, I couldn't identify everything as I didn't mod that Wii myself and I didn't do any specific diagnostics, though the Wii now refuses to update, via games or online (her Wii plainly rejects wifi) the customer expressed that what she wanted was to play any original game. So I thought updating it and removing any "visible" hacks would do. So I thought I'd check if priiloader was installed, it is so I check the hacks. Disc updates weren't blocked and no Wifi update block were installed. So I tried blocking updates to see if her problematic game could run, it brought me to a blue screen with error 02 or 03... don't remember. So... I guess I need help to unlock her wifi so I can update the system, I even tried installing sys menu 4.2 manually but I don,t have IOS70 which is required by it and most likely few others, so I kind of failed there too. I guess there were hacks installed by someone else, her system menu is 4.1 do you think there could be old system menu hacks that are preventing me from updating it?
