The JMM-AL10 test point is used to force the device (Huawei V9 Play or Honor 6C Pro) into Emergency Download (EDL) or Bootrom mode. This is typically required for service operations such as bypassing FRP (Factory Reset Protection), removing a Huawei ID, or unbricking the device when standard software methods fail. Test Point Location and Method For the Huawei V9 Play / Honor 6C Pro (JMM-AL10):

Hardware Setup: You must remove the back cover of the phone to access the motherboard.

Action: Use tweezers to short the specific gold test point to a metal ground (such as a nearby RF shield or the metal frame) while connecting the USB cable to a computer.

Device Recognition: If successful, the computer will recognize the device as "MediaTek USB Port" (since the JMM-AL10 uses the MT6750 processor) or "Qualcomm HS-USB QDLoader 9008" depending on the specific model's chipset architecture. Common Uses

FRP Bypass: Resetting the Google account lock after a factory reset.

Huawei ID Removal: Bypassing the manufacturer-level account lock. Introduction The JMM-AL10 test point is a diagnostic

Flashing Firmware: Recovering a "dead" device that cannot boot into Fastboot or Recovery mode.

Unlocking the Hardware: An Analysis of the JMM-AL10 Test Point

In the intricate world of smartphone repair and Android software modification, the term "test point" represents a critical gateway. It is the "backdoor" through which technicians revive devices that have been bricked, bypass forgotten credentials, or perform deep-level firmware flashing. Specifically, regarding the JMM-AL10—a model number associated with the Huawei Enjoy series (specifically the Huawei Enjoy 6s)—the test point procedure is a quintessential example of the intersection between hardware engineering and software recovery.

This essay explores the concept of the JMM-AL10 test point, examining its technical function, the methodology involved, and its significance within the broader context of mobile device forensics and repair.

3. Error: "Status_BROM_CMD_SEND_DA_FAIL"

Technical Procedure (Conceptual)

Note: This requires disassembly, conductive tools (tweezers or wire), and proprietary software. Incorrect execution can permanently damage the device.

  1. Disassembly: Remove the rear glass cover and the plastic mid-frame shielding to expose the main logic board.
  2. Locate the Test Points: On the JMM-AL10, the test points are typically two very small, unlabeled circular copper pads located near the HiSilicon Kirin 659 processor or the EMI shield edge. (Exact location varies, but common references point to pads near the battery connector or SIM card slot area on the board).
  3. Short and Connect: While holding the conductive tool to short the two pads, connect the phone to a PC via USB. Then, release the short.
  4. Software Interaction: The PC should detect the device as “Huawei USB COM 1.0” (or similar). Specialized flashing software can then communicate with the bootROM to write new low-level firmware.
