One problem I did face with the script is that the files fstab,extlinux.conf and boot.ini were being modified on the microSD card but the UUIDs could not be changed on the partitions because there were automounted by the system. That's why the REAME says "Make sure you have unmounted all partitions on the device before executing this script.". Could that have been the case with you too? Regards Mandar Joshi
