@UKPhil Thanks for your answer, if I read your comment I should be a lucky guy with a running ubports on my BQ M10 FHD...
I've flashed my device by using my desktop-pc with ubuntu 16.04. LTS, a usb-cable und the "magic-device-tool". There was no problem, it works perfekt. Wipe and upload the image to the device without any trouble. I am really happy, because I am only a User and I don't understand what is happening behind the GUI ! When I start the device the first screen is the white screen "BQ powered by ubuntu" and it takes more than 2 minutes before the ubports-screen comes up. From this time the device boots quickly forward...
The OS ist ubports ubuntu 15.04 r1
By the way, it's the first time I am using a forum and post something, perhaps can your remove my posting to the right place...
