F ollowing the custom ROM of the Fusion smartphone, here is an opportunity for Skyline owners to use a custom ROM on their mobile phone. Back in the day, it was a "fashion" for many to use custom ROMs or even make their own. But the primary attraction of the HMD Skyline is the ability to replace the back cover, battery and screen yourself, thanks to the collaboration with iFixit. The phone also offers long battery life, fast charging and decent performance. However, it is not without its drawbacks, such as an unattractive design, so-called cameras and limited software support. The biggest highlight of the device is its outstanding design and being the first Android device to support magnetic Qi wireless charging.

Any smartphone can face problems such as getting stuck in fastboot mode or receiving/installing software updates. The common solution to such issues is to flash the latest firmware in fastboot or EDL mode. However, HMD does not provide EDL firmware. So, fastboot flashing is the only way to flash HMD Skyline and other new HMD smartphones.

Warning: Never attempt to downgrade the HMD Skyline’s software version. It has anti-rollback enabled and will not boot on older firmware versions than what was already installed.


Below is a list of HMD Skyline firmware files that you can download. You can use the flash files to unbrick your bricked phone or update it to a newer version. If you are a researcher, you can examine the firmware and extract apps or other files from it. Whatever your use case, here are the files that are available for you.

How to flash firmware on HMD Skyline:

The files in the firmware package are only suitable for flashing the phone in fastboot mode. The files are not suitable for performing EDL (Emergency Download Mode) flashing. So, you cannot use tools like Qfil or Qpst with the firmware package.

If the bootloader is unlocked (device status: unlocked):

  • Download the firmware file.
  • Extract all the files in the firmware zip file to romAll.zip.
  • Use Android Platform Tools (Minimal ADB and Fastboot) to flash all the images to your phone.
  • For example: And so on…fastboot flash abl_a abl.elf fastboot flash boot_a boot.img
  • Finally, set slot a as the active slot and reboot the phone:
  • fastboot set_active a fastboot reboot

    If the bootloader is not unlocked (device state: locked)

    You cannot flash the firmware by yourself. A connection to the HMD Care service is needed to gain flash permission.

    You can use our Nokia phones stock ROM flashing service, and we will help you flash the firmware to the phone. Otherwise, you will need to use the services of an HMD Care center. Alternatively, you can send the device for repair using HMD’s pick-and-drop service.
