I'll post this in case anyone else likes rednand. The reason I enjoy it is because it's safe and I can have 2 separate firmware for my WiiU. Why this tutorial? Because if you are on rednand and try to update using the system menu it will fail giving you error 162-4023. You will need: 1. Mocha CFW or other patch of your choice. 2. Ftpiiu everywhere 3. Homebrew channel 4. Haxchii 5. Crediar Wup installer the first version (the Wup Y mod will give you error when trying to do this method) So this is what I did: 1. Launch Mocha CFW with Rednand, you can choose rednand or sysnand within mocha cfw menu (hold B while launching to select rednand on or off). This will give you the patches needed for ftpiiu everywhere to browse the needed files and folders. 2. Start the update and close to the end of the download click "not now" 3. Go to download management and watch the download complete. This will create the following folders: /storage_mlc/sys/update/0005001010041100/ /storage_mlc/sys/update/0005001B10051000/ /storage_mlc/sys/update/000500301001210A/ /storage_mlc/sys/update/000500301001A10A/ Now don't update. 4. Launch FtpiiU everywhere and browse those folders. 4.1. Copy each folder to your PC. 4.2. Copy the FILES from inside each folder (ONE AT A TIME) to your SDCard folder install. 5. Now while still on rednand launch crediar WUP Installer 5.1. install the first title 0005001010041100 5.2. Exit, open crediar wup installer, and install the next. 6. PROFIT After installing all those files you will be on REDNAND with firmware 5.5.2 and sysnand 5.5.1. You can disable wifi, or block updates on sysnand the way you prefer and enjoy keeping the exploit entry point and having DLC, eshop, sigpatch and a nand safe on your SD card. EDIT: THE FILES I MENTION ON THIS THREAD ARE FOR USA CONSOLE.
