Huawei Hg658 V2 Custom Firmware -

  1. Open the device; locate UART pads. Use 3.3V TTL adapter to connect TX/RX/GND (do NOT use 5V).
  2. Open terminal (115200 baud typical).
  3. Power on and interrupt bootloader at prompt.
  4. Configure network and load firmware via TFTP with bootloader commands (e.g., tftp, loadb, flash write).
  5. Verify partitions and boot. Notes: This method allows viewing boot messages and precise control; risk of bricking if incorrect flash writes executed.
  • Open PuTTY (115200 baud, 8 data bits, no parity, 1 stop bit).

    • Step C – Flash via web interface

    1. Disconnect all devices except the PC used for flashing (use LAN cable, not Wi-Fi).
