This is all I can help you.
Now about the settings for some advanced functions
To do, you need to install the application [Only registered and activated users can see links. Click Here To Register...] and make initial configuration.
After installation, go to the settings of this application in Android settings and allow it to work with external drives.
The file tools.lua should be placed in the internal memory (ibid .. in the same wear should be your iGo_xxx) along the path /storage/emulated/0/Android/data/com.caharkness.lua/files . (your drive names. /storage /emulated /0/Android /data you ALREADY have, only with their own drive names).
If the com.caharkness.lua / files directory itself is not created, create it.
The second set from the file iGO.lua will have to be configured separately
