Of course, my Wiikey 1.9b update failed. I got the error message "Test failed ... Check your connections and try again" (or similar). This poll is for those getting this "Test failed ..." message, especially if you were able to figure out why it happened. Me, I haven't got a clue why it fails. I bought my Wii with Wiikey pre-installed. The company guarantees it's a genuine Wiikey and they have no clue (they are supposed to be good, i.e. probably not a bad wiring job). I'll have to send it in for them to look at it, but ... I'm too tired to do that now. BTW, is there any reason why it wouldn't work from a DVD+RW, the only thing I buy/use, as compared to a DVD-R? I can't see why, but that's basically my only option before sending it in - could try a Wii shake also Don't give me the tip about pulling out the disc just before starting test/upgrade - it does not upgrade your Wiikey. I hope someone knows.
