Using the bmap-tools solution worked! Booting using the S2 button pressed worked and a desktop became visible!
I first downloaded the bmap file for the BeagleBone Debian 8.7 image: https://debian.beagleboard.org/images/bone-debian-8.7-lxqt-4gb-armhf-2017-03-19-4gb.bmap (linked from https://beagleboard.org/latest-images) I then followed the bmap-tools installation instructions on the following URL: https://github.com/MarkAYoder/BeagleBoard-exercises/blob/master/setup/bmap.sh <https://lh3.googleusercontent.com/-8b08EZXCnIU/WN194FrRhEI/AAAAAAAAAGI/vgu_hsW1s9E3BZFv_ZtTrNgLaggaitspQCL4C/s1600/beaglebone-bmap-tool.png> To flash the eMMC you need to change a file in the boot partition.

It shows a knight rider animation on the LEDs, indicating that the image is written to the eMMC memory.
