: Check your WADs against No-Intro dat files to ensure they are clean, verified dumps. "You're safe installing wads to nand which are good dumps (check their hashes against nointro), match your region and are not system app".
If you are a beginner, start with to understand how WADs behave. If you are experienced, treat real NAND installation like surgery: prepare, measure twice, cut once.
It is important to distinguish between the tool and the content.
If a channel WAD causes issues (like a broken banner that crashes the System Menu), you can uninstall it using the same WAD Manager. However:
Your console should be modded using an environment like Tiramisu or Aroma. vwii wad

On an original Wii, if you bricked the system menu, you could restore a NAND backup using BootMii (installed to boot2). The vWii . If you brick your vWii by installing a bad WAD, the only fix is a full NAND restore using UDPIH (a hardware-level exploit) or sending your console to a professional. There is no software-only recovery.
The original Wii had a relatively small NAND (internal storage), but the vWii partition on the Wii U is even stricter. Installing too many WAD channels consumes blocks of memory rapidly. Users often find themselves with a "Full NAND" scenario, which can cause instability or prevent the installation of essential system components later on. If you are experienced, treat real NAND installation
