Test Point Driver Huawei
With Huawei moving to HarmonyOS and using newer Kirin chips (like the 9000S), test point methods are becoming obsolete for security reasons:
For 2024-2025 Huawei models (e.g., Pura 70, Mate 60), the test point method is no longer viable without proprietary Huawei engineering boxes. The community is shifting to eMMC/UFS direct flashing (chip-off), which requires expensive programmers like EasyJTAG or Medusa Pro.
The test point driver for Huawei is not just a piece of software; it is the gateway to the motherboard’s deepest recovery functions. Whether you are a professional technician recovering a customer’s locked Huawei P30, a hobbyist unbricking a Nova 5T, or a security researcher exploring boot ROM interfaces, understanding this driver ecosystem is crucial.
To summarize the process:
Armed with this guide, you now have the complete knowledge to source, install, and utilize the test point driver for any compatible Huawei device. Remember: precision, patience, and proper research are your best allies. Proceed with caution, and happy repairing.

What is a Test Point Driver?
A Test Point Driver, also known as a Test Point (TP) driver, is a small software component used in Huawei devices to facilitate communication between the device and a computer. Its primary function is to provide a test interface for engineers and developers to diagnose and troubleshoot issues with the device.
What is the purpose of a Test Point Driver in Huawei devices?
The Test Point Driver is used in Huawei devices to:
How does the Test Point Driver work?
The Test Point Driver works by creating a virtual serial port on the computer, which allows the device to communicate with the computer. The driver uses a specific protocol to transmit data between the device and the computer.

By following this content, users should be able to understand the basics of the Test Point Driver Huawei and how to use it to test and troubleshoot their Huawei devices. test point driver huawei
To connect a Huawei device to a PC via a hardware test point, you must install the Huawei USB COM 1.0 driver
. This driver is essential for the computer to recognize the device when it is in "Emergency Download" (EDL) or factory mode, often appearing as "USB SER" in Device Manager if the driver is missing. 1. Understanding Huawei Test Point Mode
A test point is a physical contact on the device's motherboard. Shorting this point to ground (usually a metal shield) while connecting it to a computer forces the device into a low-level service mode.
: Used for repairing "bricked" devices, removing FRP (Factory Reset Protection), or flashing firmware when standard software methods fail. Connection Type : Devices in this mode are identified as Huawei USB COM 1.0 ports rather than standard mobile devices. 2. How to Install the Driver
If your device shows up as "USB SER" or an "Unknown Device" in Windows Device Manager after shorting the test points: Huawei USB COM 1.0 other devices drivers - DriverHub
To access the "Huawei USB COM 1.0" mode (Test Point mode) on Huawei devices, you need specific drivers to allow your PC to communicate with the Kirin processor's BootROM. 🛠️ The "Huawei USB COM 1.0" Driver
When you short the test point on a Huawei device and connect it to a PC, it should appear in Device Manager as Huawei USB COM 1.0. If it shows as "USB SER" with a yellow triangle, the driver is not correctly installed. Core Driver Components Driver Name: Huawei USB COM 1.0 / USB SER Driver
Purpose: Enables flashing, unbricking, and FRP (Factory Reset Protection) removal.
Compatibility: Essential for Kirin chipsets (e.g., Kirin 710, 810, 980, 990). 📥 Installation Steps To ensure a stable connection, follow these steps: Disable Driver Signature Enforcement:
On Windows 10/11, restart into "Advanced Startup" and select Option 7 (Disable driver signature enforcement). Install the Driver: With Huawei moving to HarmonyOS and using newer
Download the Huawei USB COM 1.0 driver package (often found on community forums like XDA Developers or provided by tools like UnlockTool). Right-click usb_ser.inf or use the provided .exe installer. Manual Update (If needed): Open Device Manager. Right-click the "USB SER" device -> Update Driver.
Select "Browse my computer for drivers" -> "Let me pick from a list". Select Huawei USB COM 1.0. 📍 Understanding Test Points
A test point is a physical contact on the phone's motherboard that, when grounded (connected to a metal shield), forces the device into a low-level service mode. Common Troubleshooting
Not Detecting: Ensure the battery is disconnected before shorting the test point.
Resistance Issue: Some newer models (like those with Kirin 990) may require a 10k ohm resistor on the test point cable to trigger the mode correctly.
Security Patches: Huawei released a "Test Point Break" patch for newer firmware that disables standard test point access; these may require specialized hardware or software "downgrade" methods. If you'd like to proceed, please tell me: What is your phone model? Which chipset does it have (Kirin 710, 980, etc.)? Are you trying to unbrick the device or remove FRP?
I can provide the specific test point diagram for your model once I have those details.
A Huawei Test Point Driver is a specialized piece of software that allows a computer to communicate with a Huawei smartphone while it is in "Test Point" mode. This mode is primarily used for advanced hardware diagnostics, physical data extraction, or reviving "bricked" devices that cannot boot normally. Understanding Test Point Mode
Test points are physical metal pins or pads located on a device's motherboard. When these points are "shorted" (connected together or to a ground) while the device is powered on, it forces the device to enter a special low-level boot state.
Recognition: When a Huawei device is successfully in this mode, it appears in the Windows Device Manager as Huawei USB COM 1.0. For 2024-2025 Huawei models (e
Purpose: This mode is critical for performing tasks like bypassing FRP (Factory Reset Protection), flashing board software to unbrick a device, or conducting forensic data extraction on Kirin-chipset devices. Key Scenarios for Using the Driver Huawei Physical Extraction Method: Test Points
