So here's the situation. (There's a lot of stupidity in here, and I've already beat myself up over it.) I have a US NTSC Wii bought in December 2006. This week 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. To reiterate, I guess one of the big questions I have is this: Given that I can't open the homebrew channel from bootmii (when I try it just gives me a corrupted screen), is there any other way I can launch an application using bootmii, such as from the SD card? And if I can launch an app in this way, is there anything I can do to save my system. If not, then I'm probably screwed and I'll have to send to Nintendo? But if there is still a way for me to run some software that could allow me to try reinstalling the IOS or something, then maybe there's something that can be done. But I just don't know. I'm willing to try anything short of opening up the system. I don't want to mess with the actual hardware because then Nintendo might not actually fix the system for me.
