Wii Updated from Disk - USB Loader doesn't work anymore
My problem :
Wii bought in 2009, Chipped with Wasabi, Homebrew channel installed (I don't really remember how).
I live in Canada, so it's an NTSC version?
Data and WADs on SD card
Games on USB drive, accessed with USB Loader GX.
Never updated it (I think, I don't really remember).
The Skyander Giants disc was inserted, and it asked for an update. We clicked on yes.
The USB Loader doesn't work anymore.
Current situation :
The Wii still boots.
I can go in the Homebrew channel and start USB Loader.
When I select a game, the screen goes black and "reboots" to the Homebrew menu.
I don't have "installed" or "updated" any new software on the Wii for a long time. No prill Loader or BootMii for exemple.
What "solution" would be available? Can I "downgrade" the menu? Should I install prill Loader before trying to downgrade the menu?
