CRCinAU: As a comparison, this is the mtd layout for a working r813 installed via sysupgrade:
EDIT: Nightly images to check are available at: http://openwrt.crc.id.au/ |

CRCinAU: Just to update the record, I pinged yousong regarding this as suggested by jow - got the following reply:

john: can you please test if this still happens with yousongs patch which i applied to my staging tree ? |
CRCinAU:
The LEDE Project factory images do not boot when flashed from either the web interface or the emergency recovery web site.

I CAN install openwrt-15.05.1-ar71xx-generic-mynet-n750-squashfs-factory.bin, then sysupgrade to r813 sysupgrade image without a problem.
I built r813 with a test patch from jow: http://openwrt.crc.id.au/r813/EXTRA_PATCHES/00-try-to-fix-factory-images.patch
This did not fix the factory images. I tested as far back as r555 - which also did not boot correctly when flashed via the emergency httpsvr in uboot.
