Test Point Driver Huawei |top| -

You should see a listing named exactly: HUAWEI USB COM 1.0 (COMx) (where 'x' represents an assigned port number, like COM3 or your specific port number).

Modern Huawei devices (EMUI 12 and newer, HarmonyOS) have strengthened security. In many 2021+ models (e.g., Mate 40, P50), test points no longer grant full EDL access for resetting locks—only for authorized service centers with proprietary signing tokens.

Windows will install the driver, and the device should now appear under "Ports (COM & LPT)" as Huawei USB COM 1.0 . Common Troubleshooting: Driver Not Recognizing

On Windows 10/11, restart into "Advanced Startup" and select (Disable driver signature enforcement). Install the Driver:

A Test Point is a physical electronic contact location situated directly on a smartphone’s motherboard. By shorting this specific point to the ground plane (usually a metal shield on the board) using tweezers, you force the device's chipset to interrupt its standard boot cycle.

Necessary for bypassing dead boot modes.

If your computer detects the phone but shows a driver error, follow these manual steps: Open Device Manager : Locate the "USB SER" or unknown device under Other devices Update Driver : Right-click the device and select Update driver Manual Selection Choose "Browse my computer for drivers".

Plastic spudgers, suction cups, and precision screwdrivers (typically Torx or Phillips) to safely remove the back cover and internal shields.

: A pair of metallic tweezers or a fine copper wire to bridge the test point to the ground.

Select Troubleshoot > Advanced options > Startup Settings > Restart.

To help give you the most accurate advice or troubleshooting steps, could you tell me:

The device should now appear in Device Manager as HUAWEI USB COM 1.0 or HUAWEI USB SER .

Use a suction cup and thin plastic prying tools to carefully separate the back cover. Watch out for delicate flex cables, such as the fingerprint sensor ribbon.
