My Wii's having some strange behavior that I haven't been able to explain at all. It is a JPN wii I believe to be non-autoboot chipped (picked it up when in China about 2 years ago), I regionfrii'ed it to NTSC and had it updated to 4.2U for months now with no issues. I used it some on the last weekend and everything was fine and I shutdown normally. I came in on Wenesday and found that pushing the power button I just got a blank screen, no health screen, no sound. I also can't use a remote to power on. I got BootMii put back on my SD and loaded into that and saw that I couldn't load homebrew channel either. I decided to try and load my backup NAND and I see that I still have "Unknown, boot1, boot2v3" instead of what my system is, so I'm pretty sure my NAND is toast. I'm planning now to try and format and rebuild the NAND completely, but I was wondering if there were any good guides for this since I'm not sure if regionfrii will effect things, and if I'll need to format back into Japanese or if I can stick with US system menu. If anyone has a good guide to doing this I'd be very grateful since my google-fu hasn't found anything that addresses my problems with out be being wary of totally bricking this thing. Thanks for any help you can offer.
