How to Put Your Android Device into EDL Mode

Understanding EDL Mode

EDL (Emergency Download) mode is a special state on Android devices that allows you to directly flash firmware to the device’s intenal memory, bypassing the bootloader. This is a powerful tool that can be used to repair bricked devices, flash stock firmware, and even unlock the bootloader in certain cases.

Why Use EDL Mode?

How to Enter EDL Mode:

There are several ways to enter EDL Mode. Here are the most common:

1. Hardware Key Combinations:

  • Samsung: Typically, this involves pressing and holding the Power, Volume Down, and Bixby buttons simultaneously.

  • Xiaomi: Commonly involves pressing and holding the Power and Volume Down buttons.

  • Other Brands: Check online for specific instructions for your device model.

2. Fastboot Mode:

  • Use the Command: On some devices, you can use the fastboot reboot edl command while in Fastboot Mode.

3. Deep Flash Cable:

  • Force EDL: This tool, available for purchase or DIY, can force your device to enter EDL Mode even if the bootloader is locked.

4. Test Point Mode (PCB Test Points):

  • Specific Locations: Qualcomm devices may have test points on their PCB (printed circuit board) where you can connect probes to force EDL Mode.

Important Considerations:

  • Data Loss: Entering EDL Mode will erase all data from your device. Always back up your device before attempting to enter EDL Mode!

  • Device Compatibility: Not all Android devices support EDL Mode. Make sure your device is compatible by searching online.

  • Flashing Tools: You’ll need the right flashing tools (like the Android SDK Platform Tools or specific software provided by your device manufacturer) to flash firmware in EDL Mode.

  • Risk of Bricking: If you’re not careful and don’t follow the correct steps, you could brick your device. Proceed with caution!

5 Methods To Boot EDL Mode on Any Qualcomm Device

Pre-Requirements:

  • Qualcomm SoC: This guide works for Qualcomm-powered devices.

  • USB Debugging: Enable USB Debugging on your device (you may need to enable Developer Options first).

  • USB Cable: Use a USB cable to connect your device to your PC.

  • Android USB Drivers: Install Android USB drivers on your PC.

  • ADB and Fastboot: Install the Android SDK Platform Tools (which include ADB and Fastboot).

1. Boot EDL Mode via ADB Commands:

  • Connect your device: Connect your device to your PC via USB.

  • Enable Debugging: When prompted, allow USB Debugging.

  • Open Command Prompt: Open a Command Prompt window (hold Shift and right-click in an empty area of your “platform-tools” folder and select “Open command window here”).

  • Enter the command: Type the following command and press Enter:

    adb reboot edl

  • Check for EDL: Your device should enter EDL Mode. The screen will likely dim.

2. Use Fastboot to Boot EDL Mode:

  • Enter Fastboot: Power off your device, then press and hold the Power and Volume Down buttons until you see the Fastboot Mode screen.

  • Connect your device: Connect it to your PC.

  • Enter the command: Use the “platform-tools” Command Prompt to enter one of the following commands:

    fastboot oem edl

    or

    fastboot reboot-edl

    or

    fastboot reboot edl

  • Check for EDL: Your device should enter EDL Mode.

3. Use Hardware Buttons:

  • Power Off: Turn off your device.

  • Press the Buttons: Hold the Power and Volume Down buttons simultaneously.

  • Connect to PC: Immediately connect your device to your PC. It should enter EDL Mode (you might see an LED blink).

4. Use Deep Flash Cable:

  • Purchase or DIY: You can buy a Deep Flash cable online or build one yourself.

  • Force EDL: This cable can force your device into EDL Mode, even if the bootloader is locked.

5. Use PCB Test Points:

  • Find the Test Points: Qualcomm devices may have specific test points on their motherboard where you can connect probes to force EDL Mode.

Remember, entering EDL Mode is a powerful but potentially risky procedure. Always back up your data and proceed with caution! If you’re unsure about anything, consult online forums or communities dedicated to rooting and flashing.
