The EDL test point is a specific contact area on the TCL 20 SE T671H's motherboard that allows the device to enter Emergency Download Mode when shorted. This hardware-level method is essential when the phone becomes bricked, stuck in boot loop, or unresponsive. Once in EDL mode, the device can interface with a computer using an EDL Flash Tool to flash firmware and recover functionality.
To put your TCL 20 SE T671H into EDL mode via test point, follow the instructions carefully below. This method is effective when software-based options (like ADB or Fastboot) aren't working.
