see Backup#ADB

Kill the user started adb server:

adb kill-server

Start server as root:

sudo adb start-server

Or you can basically do any adb command with sudo to start it. I typically use:

sudo adb devices

This starts the ADB server and tells me my phone is definitely hooked up.

logcat to file:

adb logcat -d > logcat-`date +%F_%H-%M-%S`.txt
