You can officially unlock bootloader in your phone by visiting the ZUK's bootloader unlock [1] site and submitting a request there.

Recovery mode is (usually, depending on implementation) a separate kernel bootable on your phone providing a segregated environment to perform certain emergency functions as factory reset, wiping cache, installing updates, data recovery, etc.

Booting to recovery mode

Please notice that this action will start your device in recovery mode which has functions that can erase all user data from the device memory. Be careful.

To start in recovery mode :

  1. Turn the device OFF
  2. Press & hold VOLUME+ button and VOLUME- button, then press POWER button
  3. Wait till green android appears on the screen
  4. Release POWER button, continue holding VOLUME buttons

Stock recovery mode

Usually limited functionality. New default Google recovery now shows "No Command" and requires user to press Power & Volume+ to show menu of available actions.

TWRP Recovery

TWRP Recovery is recovery on stereoids. It's been expanded from stock default to include plethora of additional functionality
