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:
    1. Run Decaffeinator.
    2. Let it remove the required files.
    3. Boot into Wii U System Settings.
    4. Remove the SD card.
    5. 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:

ISFShax is still functioning/installed, but not aware of any button combos I can access.

My questions:

  1. What causes vWii NAND Restorer to report "Error determining NAND type" when using a valid backup from the same console?
  2. Is there a recommended recovery procedure using ISFShax for this situation?
  3. Should I be restoring only slccmpt.bin, or is there another recovery method I should be using instead?
  4. 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.
