Microsoft & Nokia made it very difficult to modify the system by locking down the bootloader of Windows Phone devices. Now with more developments and availability of better tools, it is very easy to unlock the bootloader of Lumia phones. An unlocked bootloader opens many customization options, even making installing Android OS a possibility. Just follow the below steps to unlock the bootloader and get the root access for your Windows device.

- Over the right side, you will see a header saying, ‘Flash Original FFU‘. Under that, just browse the FFU of your device and click on Flash FFU Image. Wait while the software flashes the original firmware.
- Once your phone boots back after the flash, under ‘Unlock‘ header select ‘Unlock Bootloader‘.
- Confirm by clicking OK in the prompt to switch the phone into flash mode.
- Now under ‘Resource for Flashing‘ section, click on ‘Select your FFU image’ and browse the FFU and click ok.
- Now click on ‘Select the folder with Lumia Emergency Driver’ and select the ‘MPRG_HEX’ folder and click OK.
- Now click on ‘Optionally Select an FFU image or raw image with an Engineering-SBL3 Partition’ and browser the file for your device from the folder named ‘Engineering-SBL3s’.
- Once it’s done just hit ‘Continue’. That’s it and wait till the process is complete.
