A Test Point is a specific copper pad or hole on a smartphone’s motherboard. By shorting this point to the ground (metal shield or negative terminal), you force the device’s processor to bypass the standard boot sequence and enter a low-level diagnostic mode. This allows professional tools (like UnlockTool, UMT, or SP Flash Tool) to communicate with the phone to unbrick it or flash firmware. | Error Code | Message | Solution |
