I downloaded the 1.23 ROM files to my 860 and installed as instructed. However, on several attempts things get as far as the first post-install boot, then after calibrating the screen I get a message "Please wait, loading time and date dialog" and the system sits there forever. The Back and Forward buttons are alive and I can skip past this point, but the time/date tool will never launch; neither will several other Settings tools. Strangely, going back to a new download of 1.22 exhibits the same effect, though before I started the whole process the machine was fine on that version.
Is there some step I'm missing out?
