I'm just using the LOS 16 and works excellent.
Used the last update and i had one random reboot while using whatsapp. After that android was updating 2 apps and everything worked ok.
This is your first kernel right?
Edit: Sorry for wrong info, I mixed up replies from my email and this thread. Forgot to notice I was replying at xda. Just flash optimus zip from flashify and select to clear dalvik. It's done!
