Finally it started working. I used some 3rd party tool to format an old hdd to fat32. Then what i had to do was delete wiiflow data from the wii data menu. And now it all works! Unbelivable. Thank you very much.
I have used this tutorial to soft mod sites.google.co m/site/completesg/
I recently did a factory reset and soft modded again.
Put the files at the usb with a wii backup manager.
Tried it with wii flow and gx loader. Again no success.
No game runs, and im out of ideas how to make it work.
although i ended up accidentally changing my nand with no way of going back bc i didn't know you needed a gamecube controller to restore it (i have a wii minus/1.1, which doesn't have gamecube controller support)
and if i find the sd card i have my NAND backed up on, i can not only restore the NAND if i solder the right part in, but i can also put my NAND on dolphin, then i can play dolphin online, like PMEX Remix or MKWii Riibalanced
