ISFShax + Decaffeinator recovery help: vWii won't boot, vWii NAND Restorer "Error determining NAND type", Wii U now 160-0101

Hi everyone, I'm looking for help from someone experienced with ISFShax, Decaffeinator, and vWii recovery. I've reached a point where I'm not comfortable trying anything else without advice. System setup: Wii U (USA) ISFShax installed Tiramisu/Aroma installed Full NAND OG backup Backup files: otp.bin seeprom.bin slc.bin slccmpt.bin What happened: I was working on my vWii while setting up WiiLink. After making those changes, the vWii stopped booting. Selecting "Wii Menu" from the Wii U Menu shows a black screen for a few seconds before returning to the Wii U Menu. Priiloader is no longer accessible. What I've already tried: Ran vWii Decaffeinator. Initially it failed because FTPiiU was enabled. After disabling FTPiiU, Decaffeinator launched normally. My usual recovery method is: Run Decaffeinator. Let it remove the required files. Boot into Wii U System Settings. Remove the SD card. Perform a Wii U system update to reinstall the missing vWii titles. Unfortunately, that workflow is now broken due to a 160-0101 error being thrown at me if I attempt to access the default WiiU meny (which has forced me to boot around it into tiramisu) I also tried vWii NAND Restorer (the Wii U application), using my original slccmpt.bin and matching otp.bin from this same console. The files are in the correct location, but the application always reports: Error determining NAND type After the Decaffeinator attempt, the Wii U now throws: 160-0101 ISFShax is still functioning/installed, but not aware of any button combos I can access. My questions: What causes vWii NAND Restorer to report "Error determining NAND type" when using a valid backup from the same console? Is there a recommended recovery procedure using ISFShax for this situation? Should I be restoring only slccmpt.bin, or is there another recovery method I should be using instead? Is there a way to force the Wii U to reinstall the required vWii titles if the normal Decaffeinator update workflow can no longer be completed? I'm trying to avoid making the situation worse, so I haven't continued experimenting beyond this point. Any help would be greatly appreciated. Thank you.

I bought myself a gamecube adapter, which works fine. On my Switch it sees it as a pro controller which is fine. On PC it has problems but still works. But on my Wii U i can only use it on games like Smash Bros for Wii U. However i want to use this gamepad on Nintendont and other gamecube injects. My Wii U has Aroma cfw, is there a way i can use this adapter for this. Can anyone help me?

Not all brands work as expected.

Which brand is yours?

Nintendont recommends Mayflash GC adapters and the official Wii-U adapters. For something else, you need a 3rd party GC controller INI file, and make sure it is set to PC mode. They're currently working on the 3rd party GameCube controller support for Nintendont right now.
