@rubencarneiro : Your are welcome. By the way as Info for all, that are seeking having VollaOS on their phone, even when it comes with ubuntu touch. I think now to sideload Volla OS is much easier, because when I did Install Volla OS with ubport I had the situation, that it loaded VollaOS12.1 and got an error message that the phone has been manipulated. It took me also quite some time to update to volla OS 13. I have seen in different posts in differen forums, that people normaly live with that. But I have now no error message at the beginning and as I have understood from Ruben, that the sideload way also flashes the boot partitions, so everything is fully conform for Volla OS and secure now. If my thoughts are wrong, please correct me for the help for other Volla Phone Users. Thanks Dom
