Test Point | Jmm-al10

Locate the metallic shield plates covering the upper motherboard. Unscrew the small Phillips screws holding it in place, then lift away the shield to uncover the electronic components.

When you short the JMM-AL10 test point to ground (usually by connecting it to the metal shield or a specific capacitor), the phone bypasses the normal boot sequence and enters a state where it can communicate with specialized flashing tools (like IDT, SP Flash Tool, or HCU).

Before diving into hardware specifics, it's crucial to understand the device itself. The Huawei is the official model number for the Honor V9 Play , an entry-level smartphone announced in September 2017. It featured a 5.2-inch HD display and was powered by a MediaTek MT6750 octa-core processor, paired with either 3GB or 4GB of RAM. The phone ran on Android 7.0 Nougat out of the box.

For the JMM-AL10, using the test point allows the user to force the MediaTek MT6750 processor into its lowest operational state: the . This is the MediaTek equivalent of Qualcomm’s Emergency Download (EDL) mode. Successfully entering this mode enables a technician to perform several advanced tasks, including:

Once the back cover is off, you will see the battery and the main board. There is usually a plastic mid-frame held by screws. Double-check that the correct COM port is displayed

A common analogy is that a test point acts as a "hardware kill switch" to a phone's deepest operation mode. When a phone is "bricked" (frozen on a logo, stuck in a boot loop, or completely dead) and cannot enter Fastboot or Recovery mode via software button combinations, a test point is often the only way to re-establish a connection with the device.
