Test Point Driver Huawei Install Better

Installing the Huawei USB COM 1.0 driver is essential for repairing bricked devices or removing locks using the physical test point method. This guide will walk you through preparing your PC, manually installing the driver, and confirming the connection. 1. Preparation and Prerequisites Before starting, ensure you have the necessary environment:

Driver Files: Download the driver package (often labeled "Huawei USB COM 1.0" or "USB SER") from a reliable source like Android File Host.

Administrative Access: You must run all installers with highest privileges to ensure they register correctly in the system.

Hardware Setup: You will need a USB cable to connect your device and a tool (like tweezers) to short the physical test points on your phone's motherboard to enter "EDL" or COM 1.0 mode. 2. Putting Your Huawei Device in Test Point Mode Power off the device completely. Open the back cover to access the motherboard. Locate the specific test points for your model.

Short the test point to the ground (shielding) and simultaneously connect the device to your PC via USB.

If successful, your PC will likely recognize a new device as "USB SER" or "Huawei USB COM 1.0" in the Device Manager. 3. Step-by-Step Driver Installation

If your device shows up as "USB SER" with a yellow warning triangle, follow these manual installation steps:

Installing the Huawei "Test Point" driver—officially known as the HUAWEI USB COM 1.0 driver—is necessary for the computer to recognize your phone when you physically short the test point to enter factory mode. Step 1: Disable Driver Signature Enforcement

Modern versions of Windows (10 and 11) will block these drivers because they are often older or unsigned. Click Start > Settings > Update & Security > Recovery. Under Advanced startup, click Restart now.

Navigate to Troubleshoot > Advanced options > Startup Settings > Restart.

After your PC restarts, press 7 or F7 to "Disable driver signature enforcement." Step 2: Connect the Device in Test Point Mode

Your PC will not see the device correctly until it is physically in the right state. Power off the phone and disconnect it from the PC.

Open the back cover to locate the Test Point (refer to a diagram for your specific model).

Use metal tweezers to short (connect) the test point to the ground (usually a metal shield or the frame). While holding the short, plug the USB cable into the PC. Installing the Huawei USB COM 1

Check Device Manager; you should see a device named "USB SER" or "Unknown Device" under "Other devices". Step 3: Manually Install the Driver

Since Windows won't find this automatically, you must point it to the driver files manually.

Based on your search query, it seems you are looking for a guide or review on how to use a Huawei Test Point Driver to unbrick or repair a Huawei device.

Because "Test Point" is a hardware procedure rather than a specific software product, this review covers the methodology, the drivers involved, and the safety/risks of the process.

Step 2: Download the Correct Driver

Do not use random "Driver Updater" tools. You need the official Qualcomm QDLoader 9008 driver (modified for Huawei). A safe source is usually inside flashing tools like IDT (Huawei Download Tool) or HCU Client.

What to look for:

Troubleshooting the “Test Point” Driver

Q: I disabled signature enforcement, but I still get "The hash for the file is not present." A: You missed a step. Reboot and repeat Step 1. You must be in "Test Mode" or have signatures off. Also, disable your antivirus temporarily (Windows Defender blocks these drivers). Windows PC (Windows 10 or 11 recommended) USB

Q: My phone disconnects after 5 seconds. A: The battery is dead, or you are not holding the test point steady. Solder a small wire to the test point if possible, or use a tweezer that keeps constant pressure.

Q: Windows sees "Android" or "Huawei" but not COM 1.0. A: You are not in Test Point mode. The phone is booting normally. Reshort the test point before plugging in the USB cable.

Q: Do I need to keep signature enforcement off forever? A: No. Once the driver is installed, it will work even after a normal reboot, unless Windows updates and resets the driver policy. If it breaks, just reinstall while signatures are off.

Part 5: Flashing the Firmware (Putting the Drivers to Work)

Installing the driver is useless unless you use it. Once the test point driver is active (COM port visible), you need a flasher tool.

The "Uncertified Driver" Nightmare

Modern Windows 10 and 11 aggressively block unsigned drivers. Huawei’s test point drivers (specifically for the HS-USB Diagnostics port or MediaTek PreLoader USB VCOM port) are rarely digitally signed by Microsoft. Consequently, when you short the test point and plug in the phone, Windows sees an unknown device, tries to install a driver, fails, and labels it “Unknown USB Device (Device Descriptor Request Failed).”

The "Hidden" Driver Path

Most users fail here because they look for "Huawei Modem." In Test Point mode, you are not installing a modem. You are installing a Download/Upload interface.

Look for:

For FRP Removal only (Without full flash):

If you only need to bypass Google lock (not fix a brick), you don't need a full flash. Use tools like HCU Client (paid) or Free Huawei FRP Tool.

Step 1: Disable Driver Signature Enforcement

Since the test point driver is unsigned, you must force Windows to accept it.
