Qualcomm EDL (Emergency Download Mod) is a Qualcomm proprietary protocol that allows firmware flashing or unbricking a device when it cannot be booted up normally. It is also known as Qualcomm HS-USB QDLoader Mode.
EDL Mode is often used by device manufacturers, developers, and enthusiasts to perform advanced operations such as unlocking the bootloader, installing custom firmware, and recovering a bricked device. However, entering EDL mode typically requires specialized tools and technical knowledge, and not all devices support this mode.
Once the device is in EDL mode, it can be connected to a computer and Firmware can be flashed using specialized software, such as the Qualcomm Flash Image Loader (QFIL) or Qualcomm Product Support Tool (QPST).
It is important to note that entering EDL mode and flashing firmware can potentially brick a device if done improperly, so it should only be done by experienced users who understand the risks involved. Here’s how to reboot your Qualcomm device into EDL Mod
