Custom Firmware | Huawei Hg658 V2

This is the most critical part of understanding Huawei HG658 v2 custom firmware.

The HG658 v2 uses a Lantiq VR9 chipset for its VDSL2 modem functionality. In the open-source world, support for this chipset is "OK" but not perfect. Most custom firmware (like OpenWrt) will disable the internal VDSL modem because drivers are either proprietary or unstable.

What does this mean? If you install custom firmware, you will likely lose your telephone line (DSL) port functionality. The router will become a pure Ethernet router/switch/Wi-Fi access point. huawei hg658 v2 custom firmware

To connect to the internet via VDSL/ADSL after flashing, you would need a separate VDSL modem (like a DrayTek Vigor 130 or an old TP-Link modem in bridge mode) plugged into the WAN port.

A smaller community has ported Padavan (a fork of Asuswrt) to the HG658 v2. Padavan is lighter than OpenWrt and retains slightly better driver support for the Lantiq chipset. However, it has not been updated since 2020. Stick with OpenWrt for security. This is the most critical part of understanding

To understand why there is no custom firmware, one must look at the silicon.

  • CPU & RAM:
  • Wireless: Usually a Broadcom BCM43217 or BCM4319. Again, these require proprietary binary blobs (wl driver) which are difficult to integrate into open-source builds.

    • Conclusion: Porting OpenWrt to this device would result in a router with broken DSL (no internet), broken Wi-Fi, and no storage space. It is technically unviable for a "daily driver" custom firmware. CPU & RAM:

    You cannot flash a standard OpenWrt .bin file through the stock web interface. Huawei has signed firmware protection.

    You will need:

    Warning: This process voids warranties and can permanently brick your router if you interrupt power during the flash.
