I apologize if I shouldn't be bumping this due to the long period of time since the last post, but I couldn't find anything in the rules saying otherwise. Of course, I may just be blind.
Anyway, I got the SaveMii chip afterwards and it didn't do anything; no green light, no text, no nothing. Tried with a disc in, no disc, with an sd card in, no sd card etc. Seems the console is beyond SaveMii recovery :/ I don't trust myself with that Infectus modchip since I'd probably fail to solder it on correctly. I don't think there's anything else I can do so I'll probably just give up and try to get a new Wii at some point in the future. If there's any other options I'd be happy to hear them, but yeah.
