@Rodrigo I think @dobey has now fully answered all the technical issues you have raised in this thread, and the link I added will give you all the info you will need to take a helpful and contributive part in the UBports and Ubuntu Touch Community. Which you are more than welcome to do. We are a very friendly and welcoming community to those seeking advice and help. Negative, confrontational posts help no one and waste everyones time.
If you have any further specific questions on an item or process I would ask that you post it in the most suitable of the existing categories. Thank you for your understanding.
