Bootloader Unlock Service for Nokia 3.4 (DRS) and Nokia 5.4 (DRD)


Bootloader Unlock is now possible for HMD Global’s Nokia 3.4 (codenamed Doctor Strange or DRS) and Nokia 5.4 (codenamed Doctor Droom or DRD). Both devices share a similar motherboard (known as Bengal). Hence the process to unlock the bootloader is identical. We utilize the application bootloader derived from these phones’ engineering (prototype) models to perform the bootloader unlock. You can revert to any official version of abl once the bootloader is unlocked.

The service is performed over a remote desktop session. This can be done using TeamViewer, AnyDesk, or a remote desktop utility.


  1. Windows computer. We cannot support Linux and Mac OS.
  2. Nokia 3.4/5.4 with working fastboot mode and 10% or higher battery charge.
  3. TeamViewer or any other remote desktop app.
  4. 10 minutes of execution time (after we connect)

Product Description

Nokia 3.4 and Nokia 5.4 were the last models in HMD Global’s x.4 Nokia series. The numerical series numbers dropped thereafter in favor of Nokia phones’ X, G, and C series. Nokia has prevented bootloader unlock on most smartphones by shipping a bootloader that does not support unlocking commands. However, thanks to Hikari Calyx, who managed to access engineering units of these models to dump the application bootloader (abl), the bootloader is now unlockable on Nokia 3.4 and Nokia 5.4 by utilizing these abl binaries.

We make it easy for you to unlock the bootloader by providing guided assistance. Just buy this service, and we will unlock the bootloader for you.

You do not need to disassemble the phone or undergo complex procedures. All that you’ll need to do is to connect the phone to the computer in fastboot mode, and we will handle the rest of the process. You will see the bootloader unlock prompt on the phone in a few minutes. At this point, you must confirm the unlock by utilizing the volume and power buttons to operate the menu and approve the unlock.
