An exclusive Qualcomm protocol known as Qualcomm EDL (Emergency Download Mod) enables firmware flashing or unbricking in situations where the device is unable to boot normally. You may hear it called Qualcomm HS-USB QDLoader Mode as well.
To accomplish complex tasks like unlocking the bootloader, installing custom firmware, or recovering a broken device, device makers, developers, and enthusiasts frequently employ EDL Mode. Unfortunately, not all devices are compatible with EDL mode, and entering it usually necessitates technical know-how and specialized tools.
Devices can be flashed with firmware using specialized software like the Qualcomm Product Support Tool (QPST) or Qualcomm Flash Image Loader (QFIL) once they are in EDL mode and connected to a computer.
Flashing firmware and entering EDL mode are two processes that, if done incorrectly, could brick a device; thus, only experienced users should attempt this. To enter EDL Mod on your Qualcomm device, follow these steps:
