Some-YAWMM-Mod VS vWii-Decaffeinator

First, try installing this version of the homebrew channel. It is a slightly more updated version that contains a few vWii fixes (although none that directly affect your use case). To install it I would recommend YAWMM. (If it complains that you don't have AHBPROT, then say yes to changing the IOS and switch to 249 and that should allow you to install stuff.) This homebrew channel won't overwrite the one you currently have installed, but it does have the same banner, so I would recommend moving the HBC you have now to a random spot on the home menu so that you can differentiate them. Now that you have it installed and located, run it as normal and see if CleanRip (or any other app complaining about AHBPROT) still has that error. If it does, try the next step, if not, then woo!

- Download the zip archive from this site https://github.com/FIX94/Some-YAWMM-Mod/releases/tag/v1.0

I'm not really sure what is going on then. You can try downloading a fresh IOS 80 and System Menu WAD using NUS Downloader and installing them with a WAD manager like Some-YAWMM-MOD Note this will remove Priiloader in the process, but since you have BootMii as boot2 it is safe to do this. It would be weird if that fixed it though, since it was working recently and nothing has changed.

It's better to use the one from FIX94 since it's the most up to date one, as well as the most stable.

try another wad manager like SomeYAWMMmod

Either Some-YAWMM-Mod or WiiModLite are better alternatives.

I personally use Some-YAWMM-Mod, but YAWMM is just as good. Some-YAWMM-Mod is mostly just for WiiU compatibility, but it works just fine on Wii.

Do you have homebrew? If yes then this tool is what you need

The second step requires the WiiU side of the console be modded, which I have no idea if yours is or not. If not, follow https://wiiu.hacks.guide/#/ to get it hacked (don't worry, it's quite simple.) If it is already hacked, download vWii Decaffeinator (either from the HBAppstore or here), and launch it from the HBL. Choose light mode, and let it do its thing. Now shutdown the console, take out the SD card, and turn it back on. You'll get an error saying the SD card wasn't found and eventually end up at the home menu. If it asks for an update, then choose update. If not, go to system settings, then system update from there. Once the update is done, now go try and see if AHBPROT is fixed.

If you backed up your Wii U before, then you backed up your vWii. If you have slccmpt and otp, then you have vWii backups. But you also don't need them! Use vWii decaffeinator (Download via the link earlier on or via the Homebrew AppStore) to restore the vWii via software update. However, IT WILL NOT WORK IF YOU ARE BLOCKING UPDATES OR IF YOU DELETED THE UPDATE FOLDER!!! If Tiramisu boots up automatically every time you turn on your Wii U, then you have update blocking. You will need to disable auto-booting before using it, or it won't work! Note that you might need to rehomebrew your vWii when everything's said and done.

Download and install vWii Decaffinator and place it in the same place all the other homebrew goes

And now for why I'm so casual about you basically losing half your Wii U's functionality-- You can easily get it back! Once you redownload homebrew (preferably via this guide), and have a NAND backup (this is important in case something goes wrong!) saved to a safe place (like a cloud storage service), download something called "vWii Decaffinator" from either the Homebrew Appstore on your Wii U, or just add it manually by downloading the latest version (as of writing) here and yeeting it into wiiu --> apps with all the other homebrew.
