I've just updated the keyboard firmware and the touchpad firmware on my first-batch ISO PineBook Pro, using the community updater, and the two steps went as expected. The keyboard remained usable after completing the first step, although something inside the laptop produced a hissing sound until the second step got completed. The hissing sound was there before and after power cycling the laptop, upon the completion of the first step.
I've also completed the third, flash-kb step, which unfortunately caused the Fn + NumLock key combination to stop working. The green LED still turned on and off as a result of depressing the Fn + NumLock key combination, but the respective "numpad" keys still produced letters instead of numbers with the green LED illuminated. I haven't attempted to debug that; instead, I've repeated the two steps, ending up with the latest unpatched version of the keyboard firmware.
There are a couple of questions arising from this:

There are a couple of questions arising from this:
- What's the source of the hissing sound? The keyboard controller IC? Has anyone else noticed that sound?
- There's something wrong with the keyboard firmware patch that gets applied in the third step. Could that be fixed?
