and, what is your problem ?
you just said "I couldn't fix it" and that was it too, you didn't explain either.
Do not follow guide specific to other user's problem, yours could be different.
please, explain all you did, what you installed or replaced or deleted, which package content you used, and what is the current situation and we will see what we can do to help.
First of all, I was trying to download RiiConnect24 from https://wii.guide/riiconnect24.html . I was too notice the "Do not try this on Wii U" note. I installed one of WADS, Everybody Votes Channel, and when I returned to the Wii Menu, I saw the channel on there. Everything was normal, even though EVC could not connect to WiiConnect24. I installed the other 2 WAD files, IOS31 and IOS80. That was when I bricked my vWii.
Since then, I have tried deleting the existing slccmpt01 files from FTPiiU ( I think it was called that ) (Also I backed up the existing files too), took a NAND backup at some point before I bricked my vWii, and extracted it to the slccmpt01 folder. Still bricked.
