While there isn't a single definitive long-form article titled "JMM-AL10 test point," various technical resources and guides discuss this hardware entry point for the Huawei Honor V9 Play (JMM-AL10)

. This specific test point is a critical hardware bridge used by technicians to bypass software locks or unbrick devices that no longer boot normally. Technical Context & Purpose

The JMM-AL10 test point is primarily used to force the device into a low-level diagnostic mode (often referred to as MediaTek (MTK) USB Port

) by physically shorting a specific point on the motherboard to the ground. Bypassing Security : Technicians use this point to remove a

or bypass FRP (Factory Reset Protection) when standard software methods fail. Unbricking Test Point Location : A visual guide showing

: If a firmware update fails and the device is stuck in a boot loop, this hardware method allows for a "Dead Boot Repair" by forcing the computer to recognize the chipset for direct flashing. Software Requirements

: Once the hardware bridge is established, professional servicing tools like UnlockTool are typically required to execute the repair. Physical Location & Process Locating the test point requires disassembling the phone

, which typically involves removing the back cover and metal shields covering the motherboard. Identification

: It is usually identified as a small, circular copper pad on the PCB. On Huawei devices with the MT6750 chipset (like the JMM-AL10), it is often found near the battery connector or the EMMC chip. The Procedure

: A technician typically uses metal tweezers to connect the specific pad to a nearby metal shield (ground) while plugging the device into a PC via USB. Limitations & Risks Hardware Damage

: Opening the phone and shorting pins carries a significant risk of permanent motherboard damage if the wrong points are bridged. Modern Security

: Newer Huawei security patches have made some test point methods less effective

The "JMM-AL10" is a model of Huawei Honor 9 Lite (also known as the Honor 9i in some regions).

A test point is a specific pair of contacts (tiny copper dots or pads) on a device's motherboard. Shorting these points forces the device into a special processor mode (like Download Mode or EDL mode - Emergency Download Mode) without needing a working battery or display.

Suggested workflow for UART log capture

1. Power off and open device.
2. Locate GND, TX, RX pads. Verify with multimeter.
3. Connect GND and RX/TX lines to adapter (cross TX/RX).
4. Start serial terminal.
5. Power on device and capture boot logs; save output for analysis.

Method 2: For Dead Boot Repair (Using SP Flash Tool)

1. Download Firmware: Obtain the correct "Stock ROM" (scatter file format) for the JMM-AL10.
2. Launch SP Flash Tool: Run the tool as administrator.
3. Load Scatter: Click "Scatter-loading" and select the MT6737T_Android_scatter.txt from the firmware folder.
4. Select Download Only: Ensure you are in "Download" or "Format All + Download" (use the latter only if absolutely necessary, as it wipes IMEI).
5. Short test points (same as above).
6. Connect USB: While shorting, plug in the USB. Hear the connection sound, then release.
7. Click Download: Immediately click the "Download" button in SP Flash Tool. The red progress bar will appear, followed by a yellow bar. This indicates the BROM is being written.
8. Wait for completion: Do not disconnect until you see a green checkmark.

Detailed Technical Guide: JMM-AL10 Test Point

Hardware identification:

• The test points are usually two small gold/copper pads on the main board, often near the processor or under a shielding can.
• For JMM-AL10 (which uses a Kirin 659 SoC — not Qualcomm), the test point method is less common than on Qualcomm devices. However, Huawei/Honor devices do have test points for Download Mode.
