Unmodded wii won't boot disks
About a month ago, I tried to install the homebrew channel beta 8 after using twilight hack successfully for a while. Immediately after installation, the homebrew channel appeared so I stuck in my sd card loaded with homebrew. The first thing i noticed is that despite having about a dozen homebrew, there was no arrow on the screen to view past the first 4 options, though those loaded fine.
I then restarted my wii to play some brawl, and the error at top came up. When trying to troubleshoot, I once managed to not get that and I thought the problem was solved. It was back the next day.
Here's my major concern. The problem happened right after I installed the homebrew channel but because zelda won't boot, the homebrew channel is my only way to boot new homebrew so I can't delete it. What can I do to fix this?
The wii-ware and virtual console games work great still.
