Connect the device and type:

an output like this will come out:

Bus 004 Device 010: ID 18d1:4ee1 Google Inc. Nexus 4 / 10

18d1 is the vendor id, 4ee1 is the product id.

Numbers may change with other devices.

Create /etc/udev/rules.d/51-android.rules with:

SUBSYSTEM=="usb", ATTR{idVendor}=="18d1", MODE="0666"
SUBSYSTEM=="usb", ATTR{idVendor}=="18d1", ATTR{idProduct}=="4ee1", SYMLINK+="android_adb"
SUBSYSTEM=="usb", ATTR{idVendor}=="18d1", ATTR{idProduct}=="4ee1", SYMLINK+="android_fastboot"

replace vendor and product identifiers with yours.

Now Reload uev's rules to make these changes effective:

sudo udevadm control --reload-rules

Reconnect your device.

Type:

sudo adb devices

your device will be listed.

1. Unlock the device

Go to the bootloader:

Power off the phone
Keep volume down and power pressed together until the bootloader is shown (the bootloader has an android with the lid open like this: )

From the Linux host type:

sudo fastboot oem unlock

Select "Yes" on the phone using volume keys, confirm pressing the power key once.
