I am trying to flash my Beaglebone Black, but I think perhaps there is a failure in the S2 boot selection button.

This is correct as per the downloads page.

Seems to write correctly.
With nothing plugged in to the device
I then insert the Micro-SD Card into the BBB when unpowered.
I hold down S2 and insert the power cable.
The result is always the same, the power light indicator comes on, but nothing else happens, no other lights come on or flash even if I continue to hold down S2 or if I release it. I definitely never get the 4 LEDs coming on for a few seconds which I would expect.
If I insert the Micro-SD Card and insert the power cable without holding down S2 then lights flash, but I can’t really tell what has happened because if I plug in the display, it is just a load of white dots. If I boot up with the HDMI cable inserted though, with or without the Micro-SD Card inserted, ubuntu boots (I previously was able to flash ubuntu onto the device once).
I also tried holding down S2 when powering on with the HDMI cable inserted, same result as with no HDMI, nothing happens except the power light comes on.
Any suggestions would be much appreciated.
Cheers,
Douglas
