There have been success reports. So we know that it CAN work (in some situations). This is all new stuff, so there may be undiscovered dragons that must be slayed before it works reliably for everybody.
I (and others) will have to do this for about 60 (good) demo K3 units I got off eBay. I hope we do not run into this problem.
You (or we) may need to drop down into serial mode to fix this? Not sure yet.
