Any way to save my wii w/out sending to Nintendo?
So here's the situation. (There's a lot of stupidity in here, and I've already beat myself up over it.)
I used waninkoko's program to downgrade my IOS so that I could get wad manager to work. Everything was working fine, but then I tried to play punchout and it wanted me to do an update. I stupidly said yes b/c I didn't have the internet connection active and I figured that if it couldn't find the internet it would just skip the update (stupid move). So anyway, it updated anyway, from the disc I suppose, and now my Wii is fully bricked. No video, no sound.
I can get into bootmii, but unfortunately I never made a NAND backup (I wasn't aware of this option until after the fact).
So I'm wondering if there's anything I can do to recover my system's functionality given that I can get into bootmii. I tried going to the homebrew channel through bootmii but it won't load.
Is it possible for me to launch some kind of program from the SD card using bootmii that will let me do any kind of software changes/repairs?
Note: The Wii is not modded or anything, it only had changes to the software.
Any ideas or suggestions would be welcome. Thank you.
