Hi.
I did get mine reset yesterday after receiving the D802 from UK :-) I just used Autoscan and at first try it didn't disappear. So I went to check the User Manual. Didn't find any spesific there, so I did a new try. Now it disappeard just after rescan. Guess it was either turning ignition off or reconnecting the tool that did the work. I suppose you have already solved the problem since this post :-)
