Did you use ohneschwanzenegger to do it? If not, if you send me a full bootmii NAND backup with the keys.bin I can generate you a completely stock NAND image to flash onto your Wii. AFAIK it's the only way to completely reset a Wii to stock, the other tools always miss something.
Yes i did use ohneschwanzenegger.
I compared the 2 syschecks before and after putting the new reseted nand, and i can confirm all ios'es were removed.
Then i installed the 3 cios'es (249-250-251) using the tutorial at wii.guide/cios
Then i did a syscheck and i see the 3 cios'es were succesfully installed.
I have around 15 spare wiis with dead drives that i use either for parts or to modify them, i have one which is a similar model, and the same usb key works fine and loads games. Since the wii i'm troubleshooting has been modified a bit : RTC battery relocation+ dvd drive removal(yes it doesnt boot games if i connect the drive, i checked...) + other things, maybe the wii has a problem.
So what i'm going to do is that i'm going to swap parts between the 2 wiis and see if i can confirm the problem is in the wii motherboard itself or if i have another problem, with one of the wifi/bt modules or something else
I think this wii has a very big problem, games dont load or shows "an error has occured, press eject etc.." or shows exception DSI occured , and games doesnt want to save if there isnt already a game save in the wii...
Help me man i'm losing hope
EDIT : I FIXED IT!! remember the part when i said "i tested with a dvd drive still doesnt work"?? I started swapping parts between the 2 wiis and guess what? I SWAPPED THE 2 DVD DRIVES AND NOW IT WORKS!!! maybe dead dvd drive controller board? Idk but it works now...
The games still doesnt want to save though, for mkwii i managed to transfer a savegame file but for animal crossing the savegame manager says i need an existing savegame file... idk what to do
Thanks a lot
