Nand damage? Unusual problem on my Wii

[TheInsaneDarkOne]

Guys, I need to get a clue here to see if I´m thinking things right

My Wii started going weird last day by bugging on a green screen when I try to launch Nintendont and, if I try to run a retroarch emulator also, it locks up with that buzzing noise

The thing is, the only thing I did different was that, a night before that started to happen, I was playing the "Neo Geo Mod" on retroarch to play Garou there, nothing wrong with the game when I was playing, but, as I´ve stopped the gameplay, I simply "forced the Wii" to shutdown by holding the power button instead of leaving RetroArch and going back to HBC before shutting down

This mod, since it runs bigger games, creates a NAND page for memory storage, so, my theory there is that, by forcing the shutdown, I might have damaged a nand part or something

The thing is, if this is a possibility, how I should proceed? A full nand restoration? Or re-installing some IOSand such? I´m quite confused now since I never seen such specific thing happening, its either a full brick or something more "in your face" that we see here in the forum

Would truly appreciate some help here, let me know if you guys have something!

Not much risk in trying to restore a nand backup, or a freshly built ohneschwanzenegger nand.

You could also post a syscheck, but doesn't sound like your issue would be reflected in a syscheck https://gbatemp.net/threads/posting-a-system-check.300279/

Could your USB or sd have been corrupted or otherwise damaged/dying? Have u tried redownloading the problematic apps or trying a different device?

I have a second wii here which is newer in terms of hardware and, putting the SD card and External HD of this problematic Wii in it, I had no issues, so I think the problem is NOT on the SD card or External drive files

The funny thing is that now testing Nintendont, I just can´t enter a game via the newer USBLoader GX (version 3.0 r1272) and the Nintendont app directly on the HBC, but, it ENTERS normally if I use the old USBLoader I still have on SD (version 3.0 r1235) or the Nintendont app accessed via MMM (Multi-mod Manager)

Also, the NeoGeo mod now on retroarch can compile a game creating a Nand page, but always crashes as soon I start playing

I do have a syscheck here but, I don´t know if this might be a problem with the IOS or such, let me know, if needed, can post it here!

Tried to do a Nand backup here but my bootmii (boot2) don´t let it go trought, it says the Nand dump is from another Wii (which is nonsense since I only did a backup for this one)

Tried also using the BootMii-keyfix.exe found here in the forums, but, still couldn´t get things to work, any clues on why the software isn´t working here? Tried to do the prompt code to join the nands (also found on the forums here) and it doesn´t work either =z

Make a new nand backup and then use it to create a new compatible virgin nand.bin using ohneschwanzenegger and try restoring that
