While my Wii U is fine, I've been scarred by many horror stories like NAND corruption... and I would love to have some kind of protection against this in case it ever starts to occur. After doing some searching, I found out about redNAND, where you can boot the entirety of the Wii U on a SD card (that really says something about how good the hardware is on the Wii U)... but the latest tutorials I've seen of anyone doing it was from late 2016-early 2017 leading me to the conclusion of the fact that it has indeed been patched. Is this true? And while I'm at it, are there any good tips I should know about future-proofing (I already have a full NAND backup as well as the 4 important files backed up to the cloud so no need to worry about that)?
For anyone who stumbled upon this thread looking to answer the same question I did, here's the TL;DR:
1. Using CBHC + Mocha instead of using IOS hacks AND using a NAND backup checker in order to make sure that you aren't missing any critical files will minimize the chances of the redNAND bricking. (guide for that can be found here)
2. For NAND extraction, try using the NAND extractor found here for the SLC, SLCCMPT, and OPT as well as something called wfs-extractor for your MLC and SEEPROM files
3. Depending on how bad NAND corruption is, you might be able to do the switch to redNAND before the corruption gets too bad. But if you use IOS hacks, good luck with that
4. Unless you're really paranoid (like me), redNAND really isn't that good of a deal to switch to because you can't use the vWii. Maybe in emergency situations, but it might just be better to stay in sysNAND for now
