Jmm-al10 Test Point
is the Chinese variant of the Huawei Honor V9 Play (also known as the Honor 6C Pro in international markets). It is powered by the MediaTek MT6750 DeviceAtlas In mobile repair, a test point
is used to force the device into a special low-level mode (such as
for MediaTek devices) when the standard boot sequence fails or when you need to perform actions like FRP bypass, bootloader unlocking, or unbricking. 1. Preparation and Disassembly
To access the test point, you must partially disassemble the phone to reach the motherboard. Tools Needed
: SIM ejector tool, Pentalobe (0.8mm) and Phillips (1.5mm) screwdrivers, and a pair of fine-tipped tweezers. : Remove the SIM/SD card tray.
: Unscrew the bottom Pentalobe screws and carefully pry off the back cover.
: The fingerprint sensor is attached to the motherboard via a fragile flex cable; do not pull the back cover away too quickly. Disconnect this cable first. : Disconnect the battery connector to prevent short circuits during the process. 2. Locating the JMM-AL10 Test Point
Because the JMM-AL10 is a MediaTek-based device, the test point procedure typically involves grounding a specific pin on the motherboard while connecting the USB cable to a PC.
: On the motherboard, look for a small copper circular pad (often labeled as "KOLO" or located near the CPU/EMMC shielding).
: You must use tweezers to short this specific pad to any metal shield or "GND" (Ground) on the motherboard. 3. Entering BROM/Download Mode

A test point on the JMM-AL10 consists of small metal pads on the motherboard. Shorting these pads to the ground (GND) while connecting the device to a computer triggers a hardware-level override.
Primary Function: Forcing the device into MediaTek USB Port (VCOM) mode. Use Cases:
FRP Bypass: Removing Google Account locks after a factory reset.
Unbricking: Repairing devices stuck in a boot loop or with a "black screen" (dead boot).
Firmware Flashing: Writing raw system files directly to the eMMC storage. Location and Procedure
The test points for the JMM-AL10 are located under the back cover, requiring careful disassembly of the phone.
Disassembly: Power off the device and remove the back panel to expose the motherboard.
Locating Pads: Look for a cluster of test points near the battery connector or the CPU shielding. Note that while modern tools like UnlockTool provide specific diagrams, users often have to short a specific pad to a nearby ground (like a metal shield).
Connection: Use tweezers to bridge (short) the test point pad to the ground while simultaneously plugging in the USB cable connected to a PC.
Verification: The PC should detect a new device under Ports (COM & LPT) as "MediaTek USB Port". Alternative Methods

Understanding the JMM-AL10 test point is essential for technicians and enthusiasts working with the Huawei Enjoy 7s. When a device becomes software-bricked, stuck in a boot loop, or locked out of its FRP (Factory Reset Protection) account, standard USB debugging often fails. The test point provides a hardware-level bypass to force the device into a state where it can communicate directly with flashing software. What is the JMM-AL10 Test Point?
The JMM-AL10 is the specific model number for the Chinese variant of the Huawei Enjoy 7s. The "test point" refers to two specific metal contacts on the phone's internal motherboard. By shorting these two points—connecting them with a conductive tool like tweezers—you trigger the Emergency Download Mode (EDL) or Huawei USB COM 1.0 mode.
This mode allows the Kirin 659 chipset to accept commands from a computer even if the Android OS is completely corrupted. Why Use the Test Point?
FRP Bypass: Removing Google or Huawei account locks when you’ve forgotten the credentials. Device flashing and firmware updates : The test
Unbricking: Fixing devices that show no signs of life or won't enter Fastboot mode.
Firmware Flashing: Installing stock ROMs when the standard recovery method is unavailable.
Bootloader Operations: Performing low-level modifications that require COM 1.0 access. Prerequisites for the Procedure
Before opening the device, ensure you have the following tools and software ready:
Hardware Tools: A fine-tipped pair of metal tweezers and a precision screwdriver set. Drivers: Huawei USB COM 1.0 drivers installed on your PC.
Flashing Tool: Professional software such as SigmaKey, EFT Dongle, Chimera, or free alternatives like IDT (Image Download Tool).
Firmware: The correct XML or board firmware file specifically for the JMM-AL10. How to Locate and Use the JMM-AL10 Test Point
📍 Safety Warning: Opening your device voids the warranty and carries a risk of hardware damage. Proceed with caution. Step 1: Disassemble the Device
Power off the phone and remove the SIM tray. Carefully pry open the back cover using a thin plastic tool. You will need to remove the metal shielding covering the upper part of the motherboard to expose the test point contacts. Step 2: Identify the Points
On the JMM-AL10 motherboard, the test point is typically located near the battery connector or the Kirin chipset. It consists of a single small gold dot that must be shorted to a "Ground" (any nearby metal shield or the battery negative terminal). Step 3: Trigger COM 1.0 Mode Disconnect the battery cable from the motherboard.
Using your tweezers, touch one tip to the Test Point and the other to the Metal Shielding (Ground).
While holding the short, plug the USB cable into the phone and your PC.
Check your computer's Device Manager. Under "Ports," you should see Huawei USB COM 1.0. Step 4: Flash or Reset
Once the port is detected, you can release the tweezers. Open your chosen software, select the JMM-AL10 model, and proceed with the FRP reset or firmware flashing operation. Troubleshooting Common Issues
Device Not Recognized: Reinstall the Huawei VCOM drivers and try a different USB cable or port.
Stuck on 0%: Ensure the battery is disconnected during the initial connection process, as some tools require the phone to be powered solely by the USB.
Wrong Port: If the device shows as "Unknown Device," the short-circuit contact might not have been firm enough during the plug-in.
💡 Key Takeaway: The JMM-AL10 test point is a powerful tool for device recovery, but it requires steady hands and the correct software environment to be successful.
