The air in the small electronics repair shop was thick with the scent of solder and frustration. Leo squinted through his magnifying lamp at the Huawei P30 splayed open on his desk. It was "hard-bricked"—a high-tech paperweight that refused to vibrate, light up, or acknowledge the world.
"Soft resets won't save you now," Leo muttered. He knew exactly what he needed: the Test Point. The Hidden Contact
Under the hood of a Huawei device, the Test Point is a tiny, unassuming gold contact on the motherboard. When shorted to the ground (usually the metal shield) with a pair of tweezers, it forces the phone's Kirin processor into a special state called USB COM 1.0.
This is the "emergency room" for smartphones. It bypasses the corrupted operating system entirely, allowing a computer to talk directly to the hardware. The Missing Link: The Driver
Leo connected his tweezers, touching the gold dot to the silver shield, and plugged in the USB cable. His computer chimed, but the screen showed a dreaded yellow exclamation mark: Unknown Device.
"The driver," Leo sighed. Without the Huawei USB COM 1.0 Driver, his PC was speaking English while the phone was speaking Martian.
He navigated to his digital toolkit and initiated the install. This specific driver is the translator; it tells Windows that this silent, unresponsive slab of glass is actually a Kirin-based device waiting for instructions. The Resurrection
With the driver finally active, the Device Manager refreshed. Port (COM & LPT) -> HUAWEI USB COM 1.0 (COM5)
The bridge was built. Leo opened his flashing software, loaded the factory firmware, and clicked "Start." A progress bar—the most beautiful blue line Leo had ever seen—began to crawl across the screen.
Minutes later, the phone vibrated. The screen flickered to life, displaying the red Huawei logo. The "test point" gamble had worked. The driver had found its mark. The brick was a phone once again.

The Huawei Test Point Driver, officially known as the HUAWEI USB COM 1.0 driver, is essential for repairing "soft-bricked" or completely dead devices. It allows a PC to communicate with the phone’s processor (CPU) when the standard operating system fails to boot. 1. When to Use the Test Point
You need this driver if your device is in Emergency Download (EDL) mode or "soft-bricked".
Identification: When connected to a PC, the device appears in Device Manager as "USB SER" or "HUAWEI USB COM 1.0" (often with a yellow exclamation mark if drivers are missing).
Capabilities: Once the driver is active, you can flash firmware, unlock bootloaders, or remove FRP (Factory Reset Protection) using service tools. 2. Physical Setup (The "Test Point")
To trigger this mode, you must physically "short" specific points on the motherboard.
Hardware Prep: Remove the back cover and disconnect the battery.
The Short: Use a metal tool (like tweezers) to touch the specific test point dot and a metal ground (like the EMI shield) at the same time.
Connection: While holding the short, plug the USB cable into your PC. If successful, the PC will "ding" and recognize a new device. 3. Installation Guide (HUAWEI USB COM 1.0) The air in the small electronics repair shop
If your PC shows "USB SER" instead of the proper COM port, follow these steps to manually update it:
To install the Huawei Test Point driver (commonly recognized as Huawei USB COM 1.0), follow these steps to resolve "USB SER" errors and enable flashing or unlocking on your device. 1. Download the Required Driver
The specific driver needed for Test Point mode is the Huawei USB COM 1.0 driver.
Official Tools: You can use the HUAWEI One-click Driver Download Tool or HUAWEI PC Manager to manage standard drivers.
Specialized Driver: For manual installation, many technicians use version 2.0.6.725 (often found in technical forums like VLab) which supports Windows 8, 10, and 11. 2. How to Install (Manual Method)
If your device shows up as "USB SER" in Device Manager after shorting the test points, follow these steps to manually update it:
Open Device Manager: Right-click the Start button and select Device Manager.
Locate the Device: Look for "USB SER" or "Other Devices" with a yellow exclamation mark.
Update Driver: Right-click the device and select Update driver > Browse my computer for drivers.
Select from List: Click Let me pick from a list of available drivers on my computer. Choose Ports: Select Ports (COM & LPT) and click Next. Feature: Allows flashing of full factory firmware (including
Have Disk: Click Have Disk... and browse to the folder where you extracted the downloaded Huawei COM driver (look for the .inf file).
Select Model: Choose HUAWEI USB COM 1.0 from the list and click Next to install. 3. Verification
Once installed, the device should no longer appear as "USB SER." Instead, it will be listed under Ports (COM & LPT) as: Name: HUAWEI USB COM 1.0 (COMxx) Provider: HUAWEI Incorporated Troubleshooting Tips
Disable Driver Signature Enforcement: On Windows 10 or 11, you may need to disable driver signature enforcement to install older or unsigned COM drivers.
Battery Level: Ensure the phone's battery is above 30% before attempting to flash via test point.
Cable Quality: Use a high-quality USB cable; generic cables often fail to trigger the COM 1.0 port correctly.
Huawei’s IDT (Interactive Download Tool) only works when the phone is in COM 1.0 mode.
xloader, fastboot, modem, kernel) that is impossible in Fastboot mode.Many modern dongles (like SigmaKey, Octoplus, or Easy JTAG) now offer "Auto Test Point" or "TP Over USB" for newer Kirin chips (Kirin 710, 980, 990). These tools use a voltage glitch to simulate the test point without opening the phone. However, they are expensive and usually subscription-based. For a one-time fix, manual TP with the correct driver is the only free method.
After installing, the driver name will appear as:
