Repairing Huawei devices powered by Kirin chipsets often requires putting the phone into a specialized state known as “USB 1.0 Mode.” This mode is critical for unbricking devices, removing FRP locks, or repairing the bootloader. To make this happen, you must have the Huawei USB 1.0 Kirin Flash Device Driver installed on your Windows system.
This specific driver allows tools like SigmaKey, Chimera, or UnlockTool to communicate with the Kirin processor through a test point connection. Without these drivers, your device will show as an “Unknown Item” in the device manager, making any deep repair operation impossible.
When do you need the Huawei USB 1.0 Driver?
Normal Fastboot or Recovery modes are often locked on Huawei phones. USB 1.0 mode acts as a back-door for technicians. You need this driver if you are:
- Unbricking: Fixing a “dead” Huawei phone that won’t turn on or charge.
- Test Point Repair: Using a physical hardware jump to enter service mode.
- FRP Removal: Bypassing the Google Factory Reset Protection on Kirin 659, 710, 970, 980, and newer chips.
- Bootloader Operations: Reading codes or unlocking the bootloader via service tools.

Technician Tips for Test Point
If you don’t see the COM port, ensure your test point connection is solid. Use a fine pair of tweezers to short the point to the ground (shielding) while plugging in the USB cable. A common mistake is using a battery that is completely drained; some models require a minimum of 3.7V to trigger the port even in test point mode.
Disclaimer: Test point repair involves opening the device, which will void the manufacturer’s warranty. Proceed only if you are an experienced technician. We are not liable for any hardware damage.
