ok, then again, all should be fine I'd better use USBGX dump, so it works with cIOS mode. neek should work fine with that dump too. when you launch neek, you'll get a version of vWii which is actually a rebooted/patched/redirected system menu. from here, you cannot launch homebrew or access SD/USB anymore. to exit neek, select "return to wiiu" channel to reboot the console and clean the memory patches.
