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.
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.
If the Telnet method fails or passwords are changed, you must attack the configuration backup.

Once decrypted, you have a plain XML file.
Once inside the Linux shell (BusyBox), you have "custom" control without new firmware:
The Huawei HG658 v2 custom firmware scene is niche but alive. OpenWrt offers a second life to this outdated ISP router, transforming it into a flexible, open-source gateway. The trade-off is losing the DSL port and needing technical skill to flash via serial console.
If you have an HG658 v2 gathering dust in a drawer, grab a USB-to-TTL adapter and give it a try. You’ll learn more about networking in one evening than years of using stock firmware. But if you just want better Wi-Fi? Buy a new router. The custom firmware journey here is for the brave, the curious, and the frugal tinkerer.
Disclaimer: Modifying your router’s firmware may violate your ISP’s terms of service. Always back up your original firmware (using the md command in U-Boot) before flashing. huawei hg658 v2 custom firmware
Huawei HG658 V2 is a DSL/VDSL home gateway often provided by ISPs like Orange or Telekom. While it is a reliable workhorse for basic connectivity, finding true custom firmware (like OpenWrt or DD-WRT) for this specific model is challenging due to its chipset architecture and closed-source proprietary firmware. Review: Huawei HG658 V2 (Standard vs. Modded) Stock Experience
: Out of the box, the HG658 V2 is a capable N300 Wi-Fi router. It supports DSL and Ethernet uplinks, NAT, and basic port forwarding. However, ISP-branded versions are often "crippled," locking users out of advanced settings or forcing specific certificates onto connected devices. Custom Firmware Support OpenWrt/DD-WRT
: Official support is largely unavailable for the V2. While the older HG658b/c models have some history with , the V2 often uses a different HiSilicon chipset ( cap S cap D 5610 cap H ) that lacks wide community development. "Unlocked" Official Firmware
: Many users seek generic, unbranded Huawei firmware (e.g., version V100R001C192B019
) to bypass ISP restrictions. This "de-branding" unlocks full administrative control, though it isn't "custom" in the sense of adding new features. Performance & Hardware
: Solid for standard VDSL connections; it handles 1080p streaming and general browsing well.
: Includes a USB port that can be used for basic Network Attached Storage (NAS). Limitations : It is limited to
(N300), meaning it won't perform as well in areas with heavy Wi-Fi congestion compared to modern Dual-Band AC or AX routers. The "Patchwork" Mod Approach This is the most critical part of understanding
Since full custom firmware is scarce, the most popular "mod" for this device is repurposing it. Convert a HG658 Huawei Router to a Repeater - Instructables
Huawei HG658 V2 is a versatile VDSL2 home gateway often provided by ISPs like Vodafone, Teledyne, and various Middle Eastern or European providers. While it is a reliable modem-router, many users seek custom firmware to unlock restricted features, enable bridge mode, or use it with a different internet service provider (ISP). Hardware Overview: The Chipset Barrier
Before attempting any flash, you must identify your specific hardware version. The HG658 series has two main variants:
Standard HG658/HG658b: Often uses the Broadcom BCM63168 chipset. This version has historical support in the OpenWrt Table of Hardware, though modern support is limited.
HG658 V2: Frequently utilizes the HiSilicon SD5610H chipset. Because HiSilicon is a proprietary Huawei platform with limited open-source drivers, true custom firmware like OpenWrt or DD-WRT is generally NOT available for this specific V2 model. Unlocked vs. Custom Firmware
, "custom firmware" usually refers to debranded or unlocked stock firmware rather than a completely new operating system.
Debranded Firmware: Stock Huawei firmware without ISP-specific skins or restrictions. It allows for full control over WAN settings, VoIP, and hidden menus.
ISP Alternatives: Some users flash firmware from a different provider (e.g., using unlocked O2 Ireland firmware on a Vodafone device) to bypass regional locks. Why Flash Your HG658 V2? Editing config
Full Admin Access: Gain access to the "super admin" account (often different from the sticker on the back) to change DNS, MTU, and other advanced settings.
Bridge Mode: Many ISP-locked firmwares disable bridge mode, preventing you from using a high-end secondary router. Unlocked firmware typically restores this feature.
VLAN Tagging: Essential for using the router with ISPs that require specific VLAN IDs for IPTV or internet traffic. How to Flash Unlocked Firmware
Warning: Flashing firmware carries a high risk of "bricking" (permanently disabling) your device. Proceed at your own risk.
The only viable, modern custom firmware for the HG658 v2 is OpenWrt (version 19.07.7 or newer). DD-WRT and Tomato do not officially support this chipset.
