===== Unlock Bootloader =====
The steps below only need to be run once per device. Unlocking the bootloader will erase all data on your device! 
  - Prepare phone:
    - Enable Developer options: Settings > System > About. Tap repeatedly on “build number” 
    - Go back to System, then go to developer options. 
    - Enable **USB debugging**
    - Enable **bootloader OEM unlocking**, if present
    - Enable **advanced reboot** options.
  - Connect the device to your PC via USB.
  - Boot into fastboot mode. Open a terminal window, and type: <code>adb reboot bootloader</code> You can also achieve this via a key combination: [[android:oneplus:enter-fastboot-recovery|Enter-fastboot-recovery]].
  - Once the device is in fastboot mode, verify your PC finds it by typing:<code>fastboot devices</code> Tip: If you see no permissions fastboot while on Linux or macOS, try running fastboot as root. 
  - Now type the following command to unlock the bootloader:<code>fastboot oem unlock</code>
  - If the device doesn’t automatically reboot, reboot it. It should now be unlocked.
  - Since the device resets completely, you will need to re-enable USB debugging to continue.
  - You can check if the device is actually unlocked by executing: <code>fastboot oem device-info</code>It will tell you something like “device unlocked: true”. Please note it will ask you to erase all of your data, and that you must accept to continue.
