@fredldotme thank you so much for your awesome work. I just flashed the port a few days ago and everything is working super smooth.
I followed during the installation process your instructions and of @christophe14 (post 160). It helped me a lot.
The ubports installer caused a lot of trouble during the installation. I got a lot of error messages (they are already on github). The biggest problem for me was for some reason to boot into fastboot mode. It took me easily 40 attempts. Don't know why. For some reason the ubports installer also did not recognised the device (all the necessary drivers were installed. Switched over to the installer on fedora and did not had any problems.
Keep up the great work. I am amzed by this wonderful community and what you all have already achieved.
