Common reasons to use FFU image flashing include: "to unbrick your Lumia - to flash with other software variant aka debranding". This method allows you to completely replace the existing firmware even when standard recovery tools cannot communicate with your device.

Microsoft officially removed the Windows Device Recovery Tool (WDRT) archives for the Lumia 650 in late 2022. However, preservation communities have kept the files alive.

Even with a black screen, you can often still use the Windows Device Recovery Tool. Connect the phone to your PC using the USB cable and launch WDRT. The tool may detect your device regardless of display status, allowing firmware recovery even when you cannot see anything on the screen.

Using WDRT will wipe all data on the device, returning it to a factory-fresh state. Do not disconnect the phone during the process, as this can cause permanent damage.
