[Nexus 6 Q&A, Help & Troubleshooting] khanhathan:
Good morning everyone.

So my phone has been constantly boot looping. It restarted one night by itself and has been stuck restarting at the google logo every time. I did a flash stock soft brick with wugs rootkit and still with no success. Here is what the command prompt is saying during the process. Any assistance would help, thank you.
