alright i gut a question for you wii gurus out there i modded my brothers wii (the first one i have done) a while back it was a lu64 wii when they were first becoming moddable i used a guide on here that included a file called the lu64 fix....since this was my first mod i neglected to to make a nand backup or any of the other precautions in the event of a brick...i have since learned alot modded alot of wiis using the current guide sticky and feel it would be best to re-mod his wii to have a backup plan if the wii does brick.. and it would also be nice to get him on the latest system menu 4.2 that being said i have not ever done anything to a already modded wii would the new guide be safe to use on his wii considering his current configuration and mods that have been done to it??? would it be best to use the update files here or update through nintendo to kinda clean the old files off??? any help with this would be really appreciated
