Jmm-al10 Test Point -

Physical disassembly and probing the PCB require advanced skills. Incorrect shorting can damage the SoC or PMIC.

: Using a metallic tool (like tweezers) to "short" or connect a specific copper pad on the board to a ground point, such as a metal EMI shield. jmm-al10 test point

While holding the short, plug the micro-USB cable into your PC. Physical disassembly and probing the PCB require advanced

: Look for "MediaTek USB Port" or "Preloader USB VCOM" under the Ports (COM & LPT) section. Alternative (No PC Needed) While holding the short, plug the micro-USB cable

This paper provides a technical overview of the JMM-AL10 test point, its legitimate applications, precise location, and the necessary precautions for its use.

After removing the motherboard, locate a small unpopulated area with two copper dots. Using a multimeter in continuity mode, one dot will show 0 ohms to ground (GND test point). The other dot will have high resistance to ground – that is the signal test point .
