This guide will explain how to boot Qualcomm chipset devices into Emergency Download (EDL) Mode. The exact procedure varies with device so we'll cover the principles here.

What is the EDL mode?

EDL Mode is a mode for downloading to your device, what you're downloading (flashing / writing) to the device is the firmware or single files. EDL will come in handy in a case where reviving the device via fastboot or stock recovery isn't an option.

How do I use EDL mode?

To use EDL, you must first be able to get the device into this mode then have the firmware / files (programmer, patch, mbn, rawprogram etc) you wish to flash.
You are to use Qualcomm flash tools (like QFIL) which support flashing in EDL mode for the flashing process.

Steps to boot into EDL on Qualcomm devices

Method 1: Button Combo

• Power off the phone
  
• Hold both Volume Up and Down buttons (don't release) [if both vol buttons doesn't work then ensure to either try vol up OR vol down only]
  
• Connect the phone to a PC via a USB cord while still holding both volume buttons
  

Method 2: ADB Method

• Setup ADB
  
• Enable USB Debugging on the phone
  
• Launch ADB and run the following commands
  
  Code:

  adb devices
adb reboot edl
• The phone should boot into EDL Mode. You can verify by checking device manager for an entry like QHSUB_BULK or Qualcomm HS-USB QDLoader 9008 (if you have installed drivers)
  

Method 3: Fastboot method

Try commands like

Code:

fastboot oem edl
fastboot reboot-edl
fastboot reboot edl

Method 4: Motherboard / Test Points

Some phones require that you dismantle the phone and short two points on the motherboard in order to boot into edl mode. e.g
Infinix X608, X622 e.t.c; see https://forum.hovatek.com/thread-23298.html
Vivo Y71; see https://forum.hovatek.com/thread-26914.html
any many other models, you could run a quick search on google for edl test point for your specific qualcomm model



Important Notice
Some boxes / dongles have the Boot to EDL function
