Smartphones with a Qualcomm chipset under the hood comes with a special boot called the EDL mode or Emergency DownLoad mode. EDL mode can be used to force flash firmware files to unbrick your device or to restore the stock ROM. If your device software gets corrupted, it can happen due to flashing wrong ROM or any software which was not compatible with your device, you can revive your device by flashing firmware by going into Fastboot and Download mode. But sometimes, it can even corrupt your bootloader and due to a corrupt bootloader, you won’t be able to boot into Fastboot and Download mode, that is, your device just got hard-bricked.
