(tried editing, but can’t seem to figure out how to do that on these boards?)

I had my H90 hooked up to my setup while doing the update, and my master clock was sending clock (as they do), so I disconnected the MIDI cables from my H90 and tried updating the firmware again and it worked perfectly this time round.
Coincidence? Or is this actually something that can prevent an update? If the latter it’d be cool if it was possible to avoid having to unplug it in future updates, as I imagine many likely have theirs hooked up similarly.
