Well, if you could post the output of the changeuuid.py script, either here or there; I can have a look if anything is going wrong. To ease out your testing issues, instead of writing to a microSD everytime, you could uncompress from the original *.xz everytime and setup the raw image using losetup and partprobe before runnning ./changeuuid.py # losetup /dev/loop0 <path/to/img> # partprobe /dev/loop0 # ./changeuuid.py change /dev/loop0 /tmp/temp/ # losetup -d /dev/loop0 Regards Mandar Joshi
