I softmodded my wii u, installed homebrew and got all the emulators and roms to work, but then i installed menuify and updated the theme to darkwii and since then when i go in to my vwii and click on anything it freezes and I have to unplug my wii u to restart, is my vwii completely screwed? is there anyway of restoring it or getting it to not freeze?
The vWii does not use the same system menu as the Wii, which is why neither Priiloader nor BootMii work. This means that SM Themes will also not work, and have the potential to brick your console.
Your only hope is if you had a backup of the NAND and keys so that when, in the future, someone successfully builds a NAND re-flasher, you can send it in to them. I'm very sorry to be the bringer of bad news here
