Follow these instructions carefully and don't stray from the steps unless you are experienced enough with the flashing commands of the Teensy and want to explore other fixes.
- Create your folder structure to make this easier. Create a blank folder on your desktop and copy "otp.bin" or "slc.bin" to this folder. (You must already have one of these files to use this guide)
- Back in the Pre-Setup you downloaded a .zip file that contained the .hex file we needed when setting up the Teensy. There is another file in that .zip that we now need. It is "NANDway.py". Copy this file to the same folder that contains "otp.bin".
- Download the file "release.zip" from here (eyekey's nand tools). Copy all the files in the zip to the same directory as above.
If you ONLY have otp.bin then follow these steps. If you have a full slc.bin backup BEFORE installing CBHC then skip this section.
Start out by first dumping a copy of your current slc.bin from the Wii U.
- Start out with the Teensy disconnected from the PC.
- Make sure that your optical drive, power button and your fan are all connected to the Wii U.
- Plug in your Wii U power connector.
- Turn on your Wii U. The power LED should turn blue and your fan should spin.
- Plug in the Teensy to the PC via USB cable.
- Open a command prompt from within the folder that you created above.
- Type this command: "NANDway.py COM3 0 info" (Remove the quotes and substitute the COM3 with whatever COM your Teensy is using. See "PREPARE YOUR TEENSY" step 1.)
- You should see a reply after pinging your Wii U NAND that looks like this:
9. Dump your current slc.bin by running this command: "NANDway.py COM3 0 dump slc.bin" (again, remove quotes and replace COM3 with your correct COM port for Teensy)
10. Open the folder where you dumpted "slc.bin". It should be the same folder where you have otp.bin.
11. You should have all of eyekey's NAND tools in the same directoy as your slc.bin file if you followed the instructions above. This next command will not work if you are missing "otp.bin" from the same directory as "slc.bin" and "nandCbhcRemover.exe". Run this command to fix the CBHC install. (This will remove CBHC). Open a prompt in that directory and run this command:
- nandCbhcRemover.exe slc.bin
12. This command will fix your slc.bin by removing CBHC. Move on to the next step to flash your now fixed slc.bin.
13. In the same command prompt run this flash command (again replacing the COM port with your own. Do I need to keep saying that?) to fix your CBHC brick:
- NANDway.py COM3 0 vwrite slc.bin
That's it. You're Wii U should now boot to non-CBHC system menu allowing you to fix anything else that you need to. Test this by pluggin in the AV cord and booting again (unplug the Teensy from your PC). If it boots okay then unsolder all your connections and reassemble your Wii U.
If you still are having issues then see the Troubleshooting section
If you have a full slc.bin backup BEFORE installing CBHC then follow these steps.
You don't need otp.bin if you have a full slc.bin backup that you made before installing CBHC. You can simply flash the full backup to the NAND.
- Start out with the Teensy disconnected from the PC.
- Make sure that your optical drive, power button and your fan are all connected to the Wii U.
- Plug in your Wii U power connector.
- Turn on your Wii U. The power LED should turn blue and your fan should spin.
- Plug in the Teensy to the PC via USB cable.
- Make sure that "slc.bin" is located in the same directory as "NANDway.py".
- Open a command prompt from within the folder that you created above.
- Type this command: "NANDway.py COM3 0 info" (Remove the quotes and substitute the COM3 with whatever COM your Teensy is using. See "PREPARE YOUR TEENSY" step 1.)
