Found a URL with some links.. https://files.myharmony.com/Assets/Firmware/VersionDbDefaults2.xml
Towards bottom, there's a section called <Name>Harmony082</Name> <!-- Olive-AMR --> and Olive appears lots in the memory dumps I've been playing with.
Grab these files..
wget http://files.myharmony.com/Assets/Firmware/82/Region_{0..8}.EzHex
binwalk shows lots of interesting stuff..
Region_0 shows a file install.sh including:
reginfo="
1 Region_1.zip zImage-olive.bin kernel
2 Region_2.zip olive-image-olive.cramfs cramfs
3 Region_3.zip userconfig.ubifs usrconf
4 Region_4.zip logitech.ubifs logitech
7 Region_7.zip zImage-safemode-olive.bin kernel_sm
8 Region_8.zip olive-image-olive-safemode.cramfs cramfs_sm
"
Nice to know what each file represents!
Each of the files will be placed under Region directory..
