Hello.....
For this model installation can use any of three posted...
better use from #1 "original" and enable in your sys:
has_secondary_root=1
android_secondary_root_path="/storage/extSdCard/addons"
"addons" is folder that contain: content/ (all big files) dem, map. ... etc..
also can you change the name: see the screenshot from mine... i have "SharedMaps" instead "addons"
