As you'll see from my previous posts I had a Wiifree chip and have been unable to get Wiifit working. Managed to take my Wii back to the shop I got it modded and had it changed to the latest version of YAOSM. Now everything works just fine, even games that needed freeloader boot ok without freeloader and no more unauthorised device detected messages. Probably not what you want to hear but it's time you changed your chip for something better.
