My Wii U should be on 5.3.2, but it's spoofed to 5.5.1. I was told that I should try to update to 5.5.1 while I can, but updating through the system settings says it's on the latest version. Since I believe the spoof is permanent and the system believes I'm on 5.5.1 and won't attempt to update further than that, would I be able to update my Wii U's actual firmware to 5.5.1?
