: Safely dump the nvram , nvdata , and protect partitions to preserve device-unique IMEI registers and calibration values prior to broad system overhauls.

Check your PC's Device Manager. The phone should appear under COM ports (e.g., HUAWEI USB COM 1.0 or MediaTek USB Port ).

Refer to your specific JMMAL10 schematic. Typically, you are looking for two small gold or copper circles labeled TP or TST . They are often near the processor or EMI shield. Common points include TP_KCOL0 or TP_DET . jmmal10 test point upd

To access the test point, you must perform a hardware teardown.

: Remove the metal shielding brackets covering the main logic board by unscrewing the small Phillips-head screws. : Safely dump the nvram , nvdata ,

The utility will send a custom Download Agent (DA) file, bypass the secure boot protection, and clear the lock screen or Google account security partition within seconds.

Before you begin, you will need to gather a few essential hardware and software tools: Running a Windows operating system. Refer to your specific JMMAL10 schematic

The concept of a test point is universal and used across many smartphone brands, especially those with MediaTek or Qualcomm processors. For example, for the or Honor 7X (BND-AL10) models, the process is fundamentally the same, requiring you to open the device, locate the specific test point, and short it to ground. Other Huawei and Honor devices, like the Honor 10 (COL-AL10) or Huawei Nova (CAN-AL10) , also support this procedure. The main difference is the physical location of the test point on the PCB, which can vary significantly between models.

This 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.
