Possibly a type of bricking/Semi-bricking, hoping it can be fixed.
For a while now I've been having problems making my Wii play GameCube retail discs, it did years ago before I hacked. After my brother convinced me to let him softmod my Wii saying he knew what he was doing it wasn't hard I decided fine, so he did it (following a YouTube video which I now know wasn't smart but it seemed to have worked). Little by little I had started being greeted with Disc Read Errors for GameCube games (didn't notice till about a month ago so I can't say for sure if the way my brother modded it had anything to do with it at all), Wii games work with little to no issues (once in a while a disc tells me to eject and try again but some of my discs are a bit scuffed anyway)...GC games just don't read at all for more than a few minutes if I'm lucky. So I thought "maybe I should just rehack it myself using the guide on WiiHacks.com, they've always been a good source", so I did. Sadly the issue still persists. Here's what I've tried:
Getting a new laser put in...no good, worked the same as the old laser), was told it could be the softmod
Replaced the BC and mIOS files, no good. Tried using several different IOS (58,236,249) to install them with MMM but still nothing
Cleaned all my discs and had the Wii cleaned...No good.
Re-hacked...no good, followed the Softmod ANY Wii guide on this site, not skipping ANYTHING (even the optional steps...only thing I did different than the guide was using MMM instead of WiiMod as WiiMod would not launch the HackMii installer) and still no change.
This leads me to wonder if it could be a type of semi-brick? Please experts of WiiHacks, enlighten me here...if it's not the laser, the discs or the Softmod, what else could it be? I must be overlooking a possibility here. Could it be something to do with the NAND? I've read that the first NAND block stores important system things...perhaps there's some partial data corruption going on? These are the only things I can think of, as you can tell I'm not all that knowledgeable about all this stuff (yet), so I'm pretty much grasping at straws here...all I know is I want to fix my Wii, don't want a new Wii or a workaround (though I am much more open to a workaround than a new Wii).
Thank you for any advice, info, or anything you can offer :)
