The Huawei test point driver is a powerful but risky tool for low-level device recovery. It allows you to communicate with a bricked phone through a COM port — but requires technical skill, correct hardware understanding, and patience.
If you are not confident handling motherboard-level repairs, seek professional help. If you are a technician or advanced hobbyist, always double-check test point locations, use genuine drivers, and keep backup firmware handy.
Since many test point drivers are not digitally signed (or use expired certificates), Windows will block them by default. test point driver huawei

For a generic Huawei (e.g., Y9 2019 – JKM-LX1): The Huawei test point driver is a powerful

You must install the correct signed driver before connecting the phone in test point mode.
Some Huawei devices present as a composite device (CDC + COM). In such cases, you need to install the manufacturer’s diagnostic driver from the official HiSuite package, then manually force the test point driver via Device Manager.
Used for older HiSilicon bootloaders (Kirin 620-960). Often provided with HCU (Huawei Cleaner Utility).
