GUIDE | How to unlock the bootloader of Nokia 7.2 and Nokia 6.2(Free method)

Nokia 7.2 Bootloader Unlock

We all are aware that Nokia Mobile doesn't officially allow bootloader unlocking and the available unofficial method is a paid process. This is the reason Nokia smartphones have a bad reputation among users who want more control over their devices and love to play with different ROMs and customisation options.

The things are about to change for good with the Nokia 7.2 as the device comes with an unlockable bootloader which can be unlocked in a very simple way. Below are the steps to unlock the bootloader of the Nokia 7.2.

Warnings: 
  • If you don't know what this then stop right here as this isn't for you. But if you want to read no one can stop you. :)
  • Unlocking the bootloader will void your warranty and all the data on your phone will be erased. 
Unlocking the bootloader of Nokia 7.2 is very simple and those familiar with the process will instantly what the steps are. Before you begin the process make sure you have a back up of your data and a charged up phone.

Steps to unlock the bootloader of your Nokia 7.2 and Nokia 6.2

Step 1:

You will need ADB installed on your Windows PC. Download ADB and extract it in a folder.

Step 2: Enable Developer Options

Head to Settings > System > About Phone > Tap "Build number" seven times and if you have set a password for your phone then you will be asked to re-enter the password.  Entering the password will enable developer options.

Once your device is in bootloader/download mode, type the following command "fastboot flashing unlock". You will see a confirmation screen on your Nokia 7.2. Use the Volume Down button to highlight "UNLOCK THE BOOTLOADER" option (see image above) and use Power Key to select that option. With this done, the phone will start erasing the data stored on internal storage and will restart. The bootloader of your Nokia 7.2 is now unlocked.

Critical Unlock is recommended as it allows recovering the device in case it gets bricked. To do a critical unlock, Enter download mode once again and type the following command in the Command Prompt window "fastboot flashing unlock_critical". Now, confirm the bootloader unlock again which will erase all the data and reboot your phone back to the Android system.

The bootloader of Nokia 7.2 can be unlocked with these simple steps and I hope this attracts buyers who look for an unlockable phone and the developer community to build ROMs and various other ports for this device. These steps might also work on the Nokia 6.2. So, if you are familiar with this stuff and have a Nokia 6.2 please try it and see if it works. :)
