I managed to create a Ubuntu Zesty rootfs (actually supported arm64 instead of xenial), and now im having a really really weird behavior
if i flash the hybris-boot.img i get this in the console
markus@markus-pc:~$ lsusb -vd 0fce: | grep -i serial
iSerial 3 1ee3fc01
but, also sometimes a "charging ??/100" flashes up on the screen (rest is always black), and sometimes the LED starts to light green.
The USB Tethering seems to not fire up completly though, atleast i dont get any connection via anything to it.
The debug mode works still though.
