Hello WOB.
I tried to follow exactly same steps mentioned by you to change the installation directory(data folder directory) for iGO (iGO Primo-ANS India version).
I am trying to change the default data folder name from default name "iGO" to some other name like iGO_Ans. But no luck.
After installing modified APK, it still hunts for "iGO", instead of "iGO_Ans"

Can anyone help please?
Thanks
Regards
