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.

How is the theme use and safety in 2024? Is it still a risky process and prone to bricking?

Nope. Using the search function would be great. There is a thread for this.

Nope, you can use SDCafiine if you don't want to make it permanent, but if you want to, you can use Theme Manager, which is safer than FTP. And even if you brick it, you can restore it by having a coldboot CFW
