What MCU do you have ? Try updating it, if its the latest version then try downgrading and updating again, this may fix some of your problems, sometimes ROM updates do make the MCU go a bit funny, so its worth trying.While we're waiting for 6.0
I installed the October ROM, mainly because I wanted to try Android Auto.
I also installed L Speed, that made Lollipop usable
The issues I have with this ROM now:
Control Settings app (canbus) - starts OK but when clicking on Car Settings it crashes
Waze - installs OK but crashes at start - I guess it happens when it tries to access the network
Tomtom GO 1.2 - installs OK but crashes when clicking Get Started.
Any app that could log what's going on?
We may get 6.0, we may not, theres no guarantee, lets hope we do.
