How to Put Your Android Device into 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.

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.
