It honestly does not matter. I purchased a savemii bc I hates screwing around with the GC controller, but I still keep it plugged in anyways when doing repairs and it never once has made a difference.bazamuffin said:
The fact that he was able to get a code dump is at least a little bit better of a sign than a full brick. He might have a chance to repair it on his own, but it is slim. He could send it to N, but personally I would not.
(Not trying to make money for myself), but honestly, if I were the OP I would send the wii to me or someone else who does wii repairs bc he has a working NAND backup. Whats great is, like xflak said, since the OP has the keys, I can dump his NAND with the infectus, use betwiin to convert it over to my boot1 vulnerable wii, repair the issue, convert it back to run on his wii and nothing is lost. All savegames and everything are still in tact. It does take a little longer for me to do but it is a guaranteed fix and I still only charge $40 for the repair (which is half of what nintendo charges in the US).
If you send it to N, and you're out of warranty or they find homebrew, then they charge a lot of money and you lose everything that you worked for and had installed. Worst thing is if you did have a DVD drive that could use burned games, N makes sure every wii they send out now has the newest drive in it so you will lose that functionality.
It is worth it to send it to me or another qualified repair person. (there's like only a dozen of us worldwide that do this service)
