[Nexus 6  Original Android Development] relaxable:
Autoflash'd r64 from FrancoKernel app & on reboot, phone gets stuck on boot animation. I was on r61. PureNexus ROM (20170106 version), SELinux enforcing, encrypted FS

Resolution for now - I downloaded and flashed r63 and boots fine.

Stuck on the boot animation, I did an adb logcat and below is

1) the last few lines:
