Interesting, my variant of the M8S has only allowed the MXIII Plus version to be updated to it since about June 2017. The Lan100 version seems to brick the device outright.
I've messed around with flashing so many variations of img.gz and TAR updates that I can't really remember the order. For the current Nov 23 Lan_100, I either loaded the April Lan 100 img.gz to the June Lan 100 TAR and then to the Lan 100 TAR that balbes_150 posted Nov 23, or I flashed the April Lan 100 followed by the M8S June TAR followed by the Nov 23 Lan 100 TAR. I probably did it both ways.
Anyways, I followed 7ups advice that the June updates were the last flashable http://img.gz/TAR updates without error and then flashed the version 17.6 updates that balbes posted on Nov 23. They flashed, but still with the error as shown on my last post #706. Everything seems to run OK.
