My Wii is at version 4.1U right now. (I did it by following these steps for BannerBomber/HackMii method (3.x to 4.1 method) from GBATemp ). (I started fresh from version 3.1) I then installed a Homebrew app called USBLoader_GX. It installed OK. USBLoader_GX came up fine, I was able to see the GUI, I attached a WBFS formatted USB drive - no problem. But when I went to add any games, it gave me an error message of: "Exception (DSI) occurred!" So then I went to the Homebrew Channel to see if I can reinstall USBLoader_GX, and I was not able to see anything from the SD card. Nothing would load up. Not even a fresh SD card with the "app/appname/installation files.." scheme, the Homebrew channel would open and freeze or show up upside down, etc. So then I went to wii maintenance and deleted the Homebrew Channel, thinking I could re-do the install. I tried installing the SD card with all of the boot.elf files, .wad files etc.. just like I did in the beginning. But no luck, no dialog came up asking me to install. Could there be an issue with version 4.1U not being able to use BannerBomber? Basically, I am stuck now with my Wii at version 4.1U without Homebrew and cannot use BannerBomber v1 to reinstall Homebrew. This is a difficult problem to solve. But I figured I would ask, does anyone know how to resolve this?
