Huawei Usb Com 1.0 Frp Tool

When a Huawei device is in USB COM 1.0 mode, it means the phone is in a Serial Diagnostic Mode.

Unlock Tool is a widely used utility in repair shops. It has a specific "Huawei USB COM 1.0" tab where you can perform a "Deep Reset" or "Erase FRP."

Always ensure you have permission from the device owner or are the rightful owner before attempting these procedures. Modifying system partitions or using test points carries a risk of bricking the device permanently.

However, when the device's bootloader is corrupted, or when specific hardware key combinations are used (e.g., holding Vol-UP while connecting USB), the device may fall back to a download agent mode. In this state:

Third-party FRP tools exploit this mode by sending specific AT-like or proprietary S-commands over the COM port to reset the persistent partition (where FRP data is stored) or directly clear the FRP flag without authorization.

If that fails, try: Hold Vol Down or Vol Up only while plugging in.

The "Huawei USB COM 1.0 FRP Tool" typically follows these steps:

  • Handshake & Partition Access – The tool sends a sequence of handshake bytes to gain low-level read/write access to the eMMC/UFS storage via the CPU's downloader protocol. This content is for educational and technician training

  • FRP Data Location – On Huawei devices, the FRP flag is stored in the persistent partition (or within the nvme partition, depending on the chipset). The tool identifies the correct offset and writes zeros or a specific byte sequence to clear the FRP lock.

  • Completion – After resetting the FRP flag, the tool reboots the device. The next boot will skip Google account verification, allowing setup with any account.

  • Connect the phone to PC via USB. Confirm a new COM port appears in Device Manager.
  • In the tool select the detected COM port and the target operation (e.g., FRP remove).
  • Start the operation and wait; do not disconnect the cable until complete.
  • Reboot device and perform initial setup.

    • The tool is not universal. Compatibility depends on the chipset. It works best on:

    Not Supported: Most Kirin 980/990/9000 devices (Mate 30, P40, Mate 40) due to hardware-level FRP hardening.
