Using tweezers, to the metal shielding on the motherboard.
The device will likely appear under "Other devices" as . Manual Driver Installation : Right-click USB SER and select Update driver . Choose "Browse my computer for drivers" .
It is high-risk. It requires a steady hand and technical knowledge. It is not for beginners.
Select the driver and click if a security warning appears. Verifying the Connection
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. test point driver huawei install
A is a specific location on the smartphone's motherboard used to monitor circuitry or inject signals. By grounding this point (shorting it to a metal shield) while connecting the device to a PC, the phone enters a special service mode—Emergency Download (EDL) or COM 1.0 mode. For the PC to recognize this mode, the Huawei USB COM 1.0 driver must be correctly installed. Steps to Install the Huawei Test Point Driver Hardware Connection :
| Problem | Solution | | :--- | :--- | | | You installed the wrong driver. The device needs to appear under Ports (COM & LPT) , not Network adapters. | | Error 10: Device cannot start | Power cycle. Unplug, wait 10 seconds, re-short the pins. Windows lost the handshake. | | Error 52: Unsigned driver | You forgot Step 0. Reboot with signature enforcement disabled. | | Device disappears after 10 seconds | You aren't shorting the pins correctly. The bootloader is timing out and booting normally. |

Download one of the driver packages above. Right-click the .zip file and select "Extract All..." to a known folder (e.g., C:\Huawei_Drivers ).
When you successfully use a test point, the phone enters a low-level state called . In this state, the phone does not boot the operating system; instead, the processor initializes a serial interface, identified by the computer as HUAWEI USB COM 1.0 under the "Ports (COM & LPT)" section in Device Manager.
For advanced Huawei device repair, gaining direct access at the hardware level is sometimes the only option when a phone is bricked, stuck in a boot loop, or beyond standard software recovery. This is where the concept of a "Test Point" comes into play, along with the specialized drivers that allow a PC to communicate with the phone in this low-level emergency mode.
Once the progress bar completes, Device Manager will refresh. The yellow exclamation mark will disappear, and a structured entry will show up under reading: Huawei USB COM 1.0 (COMx) (where x represents the specific index assigned by your system).

Open your preferred service software (such as SigmaKey, EFT Dongle, Octoplus, or DC-Phoenix).
(optional, but installs base Huawei USB drivers that help stabilize connections). Step-by-Step: How to Install Huawei Test Point Drivers
A test point driver allows your computer to communicate with a Huawei device that has its hardware test points shorted. Huawei devices primarily use HiSilicon Kirin processors. When you short the correct test point to the ground on the motherboard and plug in the USB cable, the device bypasses the standard bootloader and boots into mode. Without the specific test point driver installed, Windows will display the device as an "Unknown Device" with a yellow exclamation mark, preventing service software from interacting with it. 2. Prerequisites Before Installation
Once completed, Device Manager should refresh and explicitly display under the Ports (COM & LPT) section. Verifying the Installation To ensure everything is working correctly:
Installing the test point driver Huawei requires careful attention to detail. Here are the steps to follow:
A: While drivers are not required on Linux/macOS, the test point tools (like PotatoNV cross-platform) exist for these OSes.
