Android/adb

Install ADB and Fastboot

Fastboot is included with ADB inside the dev-util/android-tools package::

Enable USB debugging

Enable the USB Debugging option on the Android device under Settings > Developer options.

For Android 4.2 and later, Developer options is hidden by default; use the following stepsː

1. On the device, go to Settings > About <device>.
2. Tap the Build number seven times to make Settings > Developer options available enable.
3. Go back to system settings and scroll down to bottom > Developer Options.
4. Now hit Enable USB-Debugging.

Tips: You might also want to enable the Stay awake option, to prevent Device from sleeping while plugged into the USB port.

Detect devices

If the device is listed then connect to the android devices shell (the first time an authorized request on the device must be accepted when typing adb shell):

List of devices attached 
8NH7N17B0XX9898        device

To run adb without root privileges then the unprivileged user account must be added to the plugdev group:

Enter shell

Set TCP port

To use adb over a WiFi connection instead of using the cable, type the below command with the USB plugged in first timeː

restarting in TCP mode port: 5555

Print IP address

To get the IP of the connected Android device (cabled connection):

192.168.1.51 

Connect

Once the IP address is known, use it to connect to the device:

connected to 192.168.1.80:5555

Now control the device as usual via adb.

Start ADB daemon

Kill ADB daemon

Sometimes it may be necessary to kill adb if the device is not showing up connect. This can occur when adb is running before connecting the device. In this case kill and restart the adb server:

System reboot

The device can be rebooted from adb:

Recovery mode

Bootloader mode
