I contacted him and he said no problem, so here is my last tested build! (20180218) https://cloud.utc.fr/index.php/s/esCfNqYPBoFaZ1F
You can flash it on top of KonstaT's build, but I recommend to erase all and do a clean install, and don't forget to make a backup!
I did not made any modifications, I just built it using a fresh Ubuntu 16.04 installation. If you want to build it yourself, I made a compilation from various guides with the exact commands that I used: https://gitlab.utc.fr/amaldona/lineageos13-openC-build-guide/wikis/home
I'll post a new build every month or so, keep tuned!
