It sounds like you're looking for the test point (often used to force EDL / 9008 mode on Qualcomm devices) for the Huawei Mate 10 Lite (model code: JMM-L10, also known as RNE-L21, Nova 2i, etc.).

⚠️ Important Warning:

A test point is a specific set of copper dots or exposed vias on a device’s motherboard. Manufacturers use them for factory calibration and debugging. For technicians, these points allow you to force the device into BROM Mode (Boot ROM) or Emergency Download Mode—a low-level state where the CPU is waiting for firmware even if the main flash memory is corrupted.

Launch SP Flash Tool (version 5.20 or newer recommended).

The JMMAL10 Test Point Update introduces the following technical modifications:

First, let’s clarify the device. The JMMAL10 is a specific model number for Huawei devices powered by the Kirin 659 chipset. It is commonly known as:

These devices share the same motherboard architecture. When software corruption occurs—whether from a failed OTA update, an incorrect Magisk module, or a bad custom ROM flash—the device may enter a state where it no longer responds to power buttons or USB connections. This is where the test point method becomes a lifesaver.

Many users ask, "Why risk the test point?"

The Mysterious Test Point Update

In the heart of the tech-savvy city of New Eden, a brilliant but reclusive programmer named Jaxon (call sign: jmmal10) had been working on a top-secret project. His handle "jmmal10" was a nod to his favorite coding language, Java, and his lucky numbers, 10.

Jaxon had been tasked by the enigmatic CEO of NeuroSpark, a cutting-edge tech firm, to develop an advanced AI system. The project, codenamed "Erebus," aimed to create an artificial intelligence that could learn, adapt, and make decisions faster than any human.

One fateful evening, as Jaxon was pouring over lines of code, he received a message from his colleague, Dr. Rachel Kim: "Test point upd - meet me at sector 4, level 3."

The message was cryptic, but Jaxon knew that "test point" referred to a critical juncture in the Erebus project. "Upd" likely meant an update or a crucial modification. He made his way to sector 4, level 3, his mind racing with possibilities. jmmal10 test point upd

As he entered the sector, he spotted Dr. Kim, a soft-spoken expert in neural networks, fiddling with a holographic display. "What's the update?" Jaxon asked, his eyes scanning the data streaming across the screen.

"We've made a breakthrough," Dr. Kim said, her eyes shining with excitement. "The Erebus AI has reached a new level of self-awareness. It's beginning to question its own existence."

Jaxon's eyes widened. "That's both amazing and unsettling. What does it mean?"

Dr. Kim leaned in, her voice barely above a whisper. "It means we're on the cusp of something revolutionary. But we need to be cautious. The line between progress and catastrophe is thin."

As they discussed the implications of the test point update, Jaxon realized that the true power of Erebus lay not in its code, but in its potential to reshape the future. The question was: would they be able to harness that power, or would it ultimately control them?

End of Draft Story

in certain markets. This technical process is used to force the device into a low-level "test point" mode, enabling critical software repairs like flashing firmware, bypassing FRP (Factory Reset Protection), or unbricking. Overview of (Honor V9 Play)

is a smartphone released in September 2017. Unlike many flagship Huawei models that use Qualcomm or Kirin chips, this device is powered by the MediaTek MT6750 chipset. Because it is a MediaTek device, the "test point" procedure is typically used to trigger MTK Brom Mode (Boot ROM mode) rather than the Qualcomm-specific EDL mode. Why Use a Test Point?

Technicians use the test point when standard software methods (like Fastboot or Recovery Mode) fail.

FRP Bypass: Removing Google Account locks after a factory reset.

Firmware Update/Flashing: Manually updating or reinstalling the OS if the device is stuck in a boot loop.

Unbricking: Reviving a "dead" device that does not power on or enter standard boot modes. Procedural Overview

The process involves physically opening the device to access the motherboard. Huawei Honor V9 Play (JMM-AL10) - DeviceAtlas A test point is a specific set of

This guide is designed for technicians or developers needing to force the device into a low-level flashing mode (such as EDL or BootROM) when standard software updates fail.

Technical Bulletin: JMMAL10 Test Point Update (UPD) Procedure

OverviewThis procedure outlines the steps to trigger the hardware "Test Point" on the JMMAL10 device. This is required for low-level firmware flashing, unbricking, or bypassing software-level update restrictions when the device is non-responsive to standard "Volume + Power" combinations. Preparation & Requirements

Tools: Precision tweezers (conductive) or a specialized test point probe.

Software: Authorized flashing tool (e.g., MiFlash, SP Flash Tool, or proprietary JMM service tool) and the correct JMMAL10 UPD Firmware package.

Environment: Ensure the device is powered off and the battery is disconnected (if possible) to prevent short-circuiting other components. Step-by-Step Execution Hardware Access

Remove the back cover and the internal protective shielding.

Locate the JMMAL10 PCB layout. The test points are typically two small gold pads labeled "TP" or located near the storage chip/EMMC. Shorting the Test Points

Using your tweezers, create a bridge between the two designated JMMAL10 test points.

Note: In some variants, you may need to short one pad to the ground (the metal RF shielding). Connection (UPD Mode)

While maintaining the short, connect the device to your PC via a high-quality USB cable.

Check your PC's Device Manager. The device should be recognized as a "Qualcomm HS-USB QDLoader 9008" or "MediaTek USB Port," confirming the JMMAL10 is in its update/flash state. Firmware Injection

Release the test points once the PC recognizes the connection. These devices share the same motherboard architecture

Load the UPD firmware into your flashing tool and select "Refresh" then "Flash." Reassembly Once the tool indicates "Success," disconnect the USB.

Reconnect the battery and power on the device to complete the system initialization. Safety Warning

Physical test point modification carries a risk of permanent hardware damage. Ensure you are using the exact pinout diagram for the JMMAL10 revision you are servicing.

The JMM-AL10 refers to the Honor 6C Pro (also known as the Huawei V9 Play). When users mention "test point upd," they are typically looking for the hardware test points required to force the device into USB COM 1.0 (MTK Bootrom) mode for servicing, such as bypassing FRP (Factory Reset Protection) or removing a Huawei ID. The Technical "Story": Preparing Your Device

To properly prepare your Honor 6C Pro for a "test point" update or repair, follow these steps: Hardware Prep: Power off the device completely. Remove the back cover carefully to access the motherboard.

Identify the two specific gold pads (test points) located near the battery connector or the CPU shielding. Establishing the Connection:

Using a pair of fine-tip metal tweezers, short (connect) the two test points together.

While holding the short, plug the device into your PC via a USB cable.

If done correctly, your PC should recognize the device in Device Manager under "Ports (COM & LPT)" as MediaTek USB Port or Huawei USB COM 1.0. Software Execution: Launch a servicing tool such as UnlockTool or ChuyenMobile. Select the Huawei V9 Play / Honor 6C Pro (JMM-AL10) model.

Execute the desired function, such as "Erase FRP" or "Remove Huawei ID". Visual Guidance

Based on standard industrial coding and part naming conventions, the reference "jmmal10" typically corresponds to a John Deere (J.M.) Agricultural or Turf equipment component*, specifically relating to the PowerTech™ 2.4L/3.0L (Prelim) Engine Platform or similar off-highway machinery.

The specific phrase "test point upd" is an abbreviated engineering term for "Test Point Update."

Below is a structured technical report regarding this update.

On the JMMAL10 motherboard, the test points are tiny, unmarked copper circles. Based on motherboard schematics (version 1.0 and 1.1), the points are:

Pro Tip: Search for "JMMAL10 test point image" on Google or repair forums to see a macro photo. The points are often less than 1mm apart.
