It seems I've made several big mistakes here: 1. I installed cIOScorp to use the disc channel to load backups; 2. after reading about all the things cIOScorp changes, I attempted to remove it (using cIOS Downgrader, the official Nintendo upgrade, and AnyTitleDeleter); 3. I updated to 4.1U, and did not downgrade again before testing a fresh installation of Hackmii. In any case, now what I've got is a "nearly" virgin NTSC Wii (LU58), running 4.1U, without Hackmii or the Homebrew channel. It runs fine (for now, at least), but obviously I can't do anything with it without the Homebrew channel. Is there any way to make this baby hackable (if that's the word) again? Thanks in advance.
