If you happen to own an Android device running a Qualcomm processor chances are that your device supports Emergency Download Mode aka EDL Mode.
EDL mode is a Qualcomm enabled feature, that is useful to unbrick device, unlock bootloader or modify protected device parameters. However, not all Qualcomm based device support it.
The easier way to boot into EDL mode is via ADB. However, if your device is bricked and you can’t boot into system or recovery, then ADB isn’t helpful. For such cases, xda user emuzychenko, has found a workaround to boot into EDL mode from Bootloader/Fastboot mode by modifying the Fastboot.exe file used to manage Fastboot functionalities.
