@Kafluke @HunterMK8 HBL2HBC does not work unfortunately. It loads to the same vWii black screen.
The way in which I bricked my vWii is just careless and stupid, so please excuse me:
I modded my original Wii years ago and when Zelda BOTW came out, I got a WiiU and modded it, so I could pass off the Wii to a friend. I hacked the vWii with a 1gb SD, then brought over the 32gb SD from my original Wii. Everything was fine except for that I couldn't get USBloader working with a USB drive to load Wii/GC games. I've been playing Zelda for so long that I didn't touch the vWii until months later (today). So i was messing around trying to get different versions of USBloader working and decided I would try WiiFlow. BUT (and here is the stupid part), I saw Priiloader in HBC and though, "that should be installed as a backup and I probably haven't yet", obviously forgetting everything from vWii hacking guides that advised against doing so. I installed Priiloader in HBC, it failed (obviously), I turned off the unit, took my SD, put WiiFlow on it for installation, then booted back up the WiiU, then the vWii into the black screen of death.
So now I need to figure out how to get vWii running again... and here I am. Please help! I miss my Wii games...
Any help in rectifying my blunder is extremely appreciated!
