Nokia 8 receives official bootloader unlock – Here’s how to unlock!

Nokia Mobile (HMD Global) has finally listened to the demands of the developer community. Nokia 8 is the first among several Nokia devices which can be unlocked. That means, there are no tricks or workarounds to follow. Simply request an unlock key directly from Nokia and you should be ready to unlock the bootloader of Nokia 8. We are also stopping our unlock service for the Nokia 8.

Bootloader unlocking allows full access to the system partitions. That is, you can decide what OS is installed on your phone. You can also make changes to various areas of the system, including rooting and flashing custom recovery (TWRP etc). Nokia already released the source code of Nokia 8, so, the device should be all ready to receive custom ROMs and development from the community.

Part 2: Unlock the bootloader

Once you have acquired the unlock key, it is time to use the key to unlock your bootloader. The unlock key contains an encrypted signature which is a combination of your IMEI and other details. So, it is specific to the device which was used to generate the unlock file.

  1. Ensure that ADB and Fastboot are installed on your device. It is a part of Android Platform Tools. But if you do not need the entire package, then you can install just the minimal ADB and fastboot.
  2. Boot your Nokia 8 to download mode by pressing and holding Volume down key and then connecting USB cable from a power off state.
  3. Open Windows command prompt (or Powershell) if you are using Windows. Mac and Linux users should open the Terminal.
  4. Send the following commands to unlock the bootloader.
    fastboot flash unlock unlock.key
    fastboot oem unlock
  5. Accept the unlock prompt on your phone and wait for the device to wipe.
