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.

So when I load the transfer tool on my Wii u and my USB Helper on my PC, it says this "The requested FTP command is not supported when using HTTP Proxy." so I was just wondering if you guys could help me?

This tool doesn't allow you to install titles that are too big for your SD card. All this tool does is transfer the files over the network from your PC to the SD card, located inside your Wii u. The files still need to fit on your SD card in order for this tool to work.
