Note to anyone who has enabled multi boot (two boot partitions/operating systems)
Do not Install the basebuild on the 2nd partition.
The online downloader and flash tool overwrites partition 1, instead of the usual outcome of images Flashing the partition on which it was ran.
Luckily I'd recently made a backup of my own build, that used to be on partition 1. So I flashed openatv 6 over the base build image on Partition 2 and then flashed the backup over it
