I have an igo folder in internal memory and on sd and Primo works on my smartphone, which is the same smartphone as De5i (s4 mini)
However in that (internal) igo folder are only these folders:
config (in it a folder 'devices', which does not hold the s4 mini)
No igo folder, so De5i, what is in that igo folder in the igo folder??
I have the same lines in sys.txt. I commented out the linked root list, but that appears to not make any difference.
On my first attempts, Primo did startup and close right away until I put the basemap, a language file and a voice in the "main" content folder in internal memory.
