Posted this in the wrong forum, can't delete it there, mods wouldn't let me post here(hopefully goes through this time). Believe I completed a successful flash(crossflash? on what was a UD03?), but now won't read either of 2 rented discs to test, Blu or UHD, will play dvd. Many thanks to Coopervid ...
