What you need:

Steps:

  • Detection: The tool should automatically detect your device connected to the COM port.
  • Start Flashing: Click Next or Start. The progress bar will move. Do not touch the device or computer until the process reaches 100% and the tool prompts you that it is finished.
  • Factory Reset: It is often recommended to reset the device to factory settings after a manual flash to prevent configuration conflicts.

    • Before any update (even OTA), export your current configuration. This saves you hours of re-entering APN settings, Wi-Fi passwords, and port forwards.

    Overall:
    The E5573CS-323 is a legacy device (released ~2018-2019). Huawei no longer supports it directly. If you must update, first check your current firmware version (192.168.8.1/api/device/basic_status). If it ends in ...21.333.xx or higher, there’s likely no official update available anywhere.

    Better use of time: If the device is unstable, try factory reset, change Wi-Fi channel, or disable power saving mode – not a firmware hunt.

    Cause: The device requires >50% battery. Fix: Keep the device plugged into a charger (2A output) during the entire update.

    This is the safest method. It checks for official updates specifically approved for your specific device model.

    What you need:

    Steps:

  • Download & Install: If an update is found, click Download. Once downloaded, the interface will prompt you to install. Confirm the action. The device will reboot automatically several times.

    • Note: If it says "No updates available," your carrier has not pushed a new version to the server yet.
