What should one see when it updates, and how long should it take? Is there some way to force it?
I’ve Power cycled mine four times, and it still boots normally (Huron) and still shows v2.8.8 for the Bridge. I tried it with and without the SD card.
On my DSJ, after a single power cycle, the update was available on the selectable “Bridge II” update screen. A long press of the selection button started a process which showed the words “updating” (I think), preceded by an asterisk or something that was flickering very quickly - too fast to really tell what it was. Anyway, it at least demonstrated that something was indeed happening.
I left the DSJ to update, so don’t know exactly how long it took. But was definitely more than a few seconds, and no more than a few minutes.
