I had the same FC "voice commands" as smccloud. What's strange is that while that was going on I was unable to boot into recovery to wipe the data / cache. I could get the Android guy to come up with the start + x method, but it wouldn't respond after that.
I'm now halfway through the SBF process (installing TBH GB). Ah well, serves me right for not wiping data during the upgrade to .8.
