This guide will explain how to boot Qualcomm chipset devices into Emergency Download (EDL) Mode. EDL enables you read or flash a Qualcomm Android phone's stock rom.

Method 1: Button Combo

• Power off the phone
  
• Hold both Volume Up and Down buttons (don't release)
  
• 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
