First:

These are the correct statements

[folders]
has_secondary_root=1
android_secondary_root_path="/sdcard0/Addons"
data="/sdcard0/Addons"

and this is a wrong statement:
android_secondary_root_path="/sdcard0/Addons

Sec.

To avoid problems with the creation of the file speedcam.spdb radar "speedcam.txt" files - ready file speedcam.spdb better to put in - /sdcard0/Addons/content/speedcam

Third.

You can try to install a "new" version of iGO
environment ART (Android folder / data /) - here you have an example - [Only registered and activated users can see links. ]
although I fear that the amount of memory may not be sufficient.

PS.
As the "little" was mixed throughout the system - I suggest you uninstall all cleaned up trash, residues and erroneous file - and then installed all over again.
Remember - to delete the contents of the SAVE, folder License - leave only files lic or Lyc, and delete the old files nng of the entire device.
good luck - like that - write
