No full custom firmware like OpenWrt.
Reasons:
What you can use instead:
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.
If you’ve been holding onto a Huawei HG658 v2 router—perhaps it was your ISP’s “freebie” from a few years back—you might have noticed it’s showing its age. Stock firmware often feels sluggish, lacks advanced features like VPN support or VLAN tagging, and can leave your network vulnerable to unpatched exploits.
But before you toss it in the e-waste bin, let’s talk about custom firmware.
Flashing a third-party OS onto the HG658 v2 can unlock hidden potential. However, this journey comes with significant risks and rewards. Let’s break it down.
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.
Potentially, yes—but with heavy caveats.
The HG658 v2 is based on a Broadcom chipset (BCM6361), which is notoriously tricky. Unlike routers with Atheros or MediaTek chips, Broadcom requires closed-source drivers. This means you won’t find OpenWrt (fully open) support.
However, there are two main custom options:
Huawei HG658 V2 does not have a widely available or stable custom firmware (like OpenWrt or DD-WRT) because it is based on Broadcom chipsets
, which often use proprietary drivers that are difficult for open-source developers to support. Super User Status Summary OpenWrt Support: no official support in modern OpenWrt releases
. While similar models like the HG658b/c exist in the hardware table, they are often marked as partially supported or community-maintained with significant limitations. Hardware Barriers: The device typically uses the Broadcom BCM63168
SoC. Broadcom's "closed source" nature makes it a poor candidate for custom firmware. ISP Restrictions: units are issued by ISPs (e.g., Orange, TPG) and have locked bootloaders
or custom firmware that automatically reverts any manual changes. Existing "Workarounds"

Custom firmware options for the Huawei HG658 V2 do not include mainstream Linux-based platforms like OpenWrt or DD-WRT. Instead, users must rely on unlocked original equipment manufacturer (OEM) or ISP-unrestricted firmware to gain full administrative control.
This guide details why third-party firmware support is restricted for this model, what alternatives exist, and how to flash unrestricted firmware safely. 🛠️ Hardware Profile: Huawei HG658 V2
Understanding the hardware is essential before attempting any modifications. The Huawei HG658 V2 is a popular, budget-friendly VDSL2/ADSL2+ gateway often distributed by telecom providers. Specification Processor (CPU) Broadcom BCM63168 (MIPS architecture, dual-core at 400 MHz) RAM 128 MB DDR2 Flash Memory 128 MB NAND (e.g., Spansion S34ML01G or similar) Wi-Fi 802.11b/g/n (2.4 GHz, up to 300 Mbps) with MIMO technology Wired Interfaces 1× 10/100 Mbps WAN, 3× 10/100 Mbps LAN ports Expansion & VoIP 1× USB 2.0 port, 2× RJ11 FXS phone ports 🛑 The Status of OpenWrt & DD-WRT on HG658 V2
If you are hoping to flash OpenWrt or DD-WRT, you will encounter major roadblocks:
Broadcom Chipset Constraints: The Broadcom BCM63168 SoC relies heavily on proprietary, closed-source drivers for its VDSL modem and Wi-Fi chipsets. Because Broadcom does not provide open-source code for these components, open-source developers cannot easily build fully functional firmware.
No Official Support: The OpenWrt Table of Hardware lists the earlier HG658b/c as having limited support, but the HG658 V2 does not have an official OpenWrt or DD-WRT release.
Risk of Bricking: Trying to flash a modified or experimental build for a similar chipset via the web GUI will almost certainly cause a hard-brick, which requires a serial connection (TTL/UART) to recover. 🔓 The Alternative: Unlocked & Unrestricted OEM Firmware
While true third-party custom ROMs do not exist, users can flash unlocked generic firmware (such as the Global/Retail Huawei firmware) or unrestricted ISP versions.
Many internet service providers disable features like bridge mode, custom DNS, parental controls, and VoIP configurations. Flashing the official, unrestricted B021 or similar global firmware versions re-enables these advanced tools. Key Benefits of Unlocked Firmware
Huawei HG658 v2 is a veteran VDSL2 modem-router often issued by ISPs like Vodafone, Etisalat, and TE Data. While the hardware is robust for a budget device, the stock ISP firmware is notoriously "locked down," hiding advanced features. This review explores the impact of installing custom or unlocked firmware. The Verdict: Is It Worth It?
For most users, flashing custom firmware on the HG658 v2 is less about "overclocking" and more about liberation
. If you are tired of ISP-imposed restrictions on DNS settings, VoIP configurations, or bridge mode, it is a game-changer. However, if you are looking for modern Wi-Fi 6 speeds or advanced SQM bufferbloat management, the aging hardware remains a bottleneck. Performance & Features Unlocked VoIP Settings:
Most ISP versions lock the VoIP tab. Custom firmware (often the generic "Huawei Global" version) allows you to use any SIP provider. Full Bridge Mode:
Custom firmware reliably enables Bridge Mode, allowing you to use the HG658 v2 strictly as a modem while a more powerful router (like an ASUS or TP-Link) handles your network. DNS Control:
ISPs often hardcode their own DNS. Custom firmware lets you set Google (8.8.8.8) or Cloudflare (1.1.1.1) directly at the router level for better privacy and speed. Stability:
The generic Huawei firmware often feels snappier than ISP versions laden with "diagnostic" background tasks that can cause the device to overheat or reboot under heavy load. Hardware Limitations No firmware can fix the HG658 v2's physical specs: Wi-Fi N300:
You are stuck with 2.4GHz 802.11n. In crowded apartment buildings, speeds will still suffer from interference. Fast Ethernet:
The ports are 10/100 Mbps. If you have a fiber connection over 100Mbps, this router will cap your wired speeds regardless of the firmware. Installation Risks Complexity: huawei hg658 v2 custom firmware
Flashing this specific model often requires the "Web UI" method or, in some stubborn cases, a TTL-to-USB serial connection to the motherboard. The "Brick" Factor:
Using the wrong firmware version (e.g., trying to flash HG658 software onto a ) will render the device useless. ISP Compatibility:
Some ISPs use specific authentication (like TR-069) that might be harder to re-configure manually once the "plug-and-play" ISP firmware is gone. Final Summary
Users on VDSL plans (up to 100Mbps) who want to use their own VoIP service or need a cheap, reliable VDSL modem to put into bridge mode.
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
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?
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.
Huawei HG658 V2 is a versatile VDSL2 home gateway often deployed by ISPs. While official firmware provides stable connectivity, users frequently seek custom or "unlocked" firmware to bypass ISP restrictions, enable bridge mode, or gain advanced networking controls. The Current State of Custom Firmware True third-party firmware—such as OpenWrt , DD-WRT, or Tomato—is currently not supported for the Huawei HG658 V2
. This is primarily due to the device's specialized hardware: Chipset: It uses the Broadcom BCM63168 SoC.
Architecture: It features a MIPS-based architecture with a CFE bootloader and 128 MiB of NAND flash.
Broadcom Limitation: Open-source support for Broadcom DSL chipsets is notoriously difficult because the DSL modem drivers are closed-source "blobs," which makes them incompatible with standard OpenWrt or Tomato builds. Unlocked Official Firmware vs. Custom Firmware
Since standard custom ROMs are unavailable, the most common "custom" solution is flashing unlocked official firmware. The Problem: Many ISPs (like TPG or STC) ship the
with "crippled" firmware that hides settings for Bridge Mode, custom DNS, or VoIP.
The Solution: Community members often use general Huawei firmware (V100R001Cxxx) that has not been modified by an ISP. Flashing this version restores access to all hidden menus. Why Users Seek Custom Solutions Installing unlocked or modified firmware on the offers several advantages:
Custom firmware support for the Huawei HG658 V2 is extremely limited due to its Broadcom BCM63168 chipset, which relies on proprietary drivers that are not fully supported by major open-source projects.
While you cannot easily install popular firmwares like OpenWrt or DD-WRT, there are alternative ways to "unlock" the device's potential. 🛠️ Firmware Compatibility Status Firmware OpenWrt ❌ Not Supported
Limited support for the BCM63168 SoC; wireless drivers are often non-functional. DD-WRT ❌ Not Supported No active development for this specific Huawei model. Tomato ❌ Not Supported
Tomato focus is primarily on specific Broadcom ARM/MIPS chips not used here. Unlocked Stock ✅ Available
Generic or "unlocked" versions of the Huawei stock firmware can remove ISP restrictions. 🔓 Unlocking Options
Since a full "custom" OS is unavailable, users typically pursue one of these two paths to regain control: 1. Flashing Unlocked "Global" Firmware Many
units are locked to specific ISPs (like Orange, Vodafone, or Superonline).
Goal: Replace the ISP-branded firmware with a generic Huawei version to unlock hidden menus (like VOIP settings or TR-069 management). No full custom firmware like OpenWrt
Warning: Flashing the wrong version can "brick" the device. Users often look for versions like B021 or B022 on community forums to improve stability. 2. Converting to an Access Point (AP)
If you cannot flash new firmware, you can bypass the limited software by turning the device into a dedicated Wi-Fi bridge or AP.
Steps: Disable DHCP, assign a static IP within your main network's range, and connect it via LAN-to-LAN to your primary router. How to install "Advanced Tomato" (Custom OS) on your Router

Some useful resources to get you started:
The summer of 2018 was the summer the internet broke for Leo.
Not the whole internet, of course. Reddit still worked. YouTube, mostly. But for Leo, a university student renting a converted garage in Berlin, the bottleneck was a hideous, black-and-silver plastic obelisk blinking in the corner: the Huawei HG658 v2.
It was the ISP’s standard-issue router. And it was a liar.
Every evening at 8:03 PM, like a depressed office worker clocking out, the Wi-Fi would stutter. Video calls froze into cubist nightmares. His flatmate, Mira, would scream from the other room: “Did you unplug it again?!” The admin panel—when it loaded—showed pristine signal strength. But speed tests told a different story: 0.3 Mbps down, 5 up. Asymmetrical agony.
Leo tried everything. He changed channels. He disabled WMM. He wrapped the antennas in tinfoil like a paranoid chef. Nothing worked. The HG658 v2 had a curse: its stock firmware was a bloated, telemetry-spying, session-limiting disaster. It crashed under the load of three devices and a smart bulb. What you can use instead:
Then he found The Forum.
Tucked away on a Ukrainian tech board, deep in a thread titled “HG658_v2_unlock_ultimate”, was a user named s3rgei. His avatar was a pixelated fox. His post count: 47,000. His tone: tired.
“Stock firmware is trash,” s3rgei wrote. “But the bootloader is lazy. You can flash OpenWrt if you know how to lie to the serial port.”
Below was a custom firmware image: openwrt-hg658v2-squashfs-custom.bin. Size: 4.2 MB. The comments were a chorus of broken English gratitude. “Works perfect!” … “VOIP no, but speed yes.” … “My router no longer reset at 2am. Thank you fox man.”
Leo hesitated. Flashing custom firmware on a locked ISP router was like performing open-heart surgery with a butter knife. One wrong move, and the HG658 v2 would become a brick. A black, heat-generating brick.
But at 8:05 PM that evening, after his third dropped Zoom call, he snapped.
He downloaded the file. He stripped an old USB-to-TTL serial cable from an Arduino kit. He pried open the router’s case—the plastic clips snapping like chicken bones. Inside, the PCB was bare, unremarkable, except for four tiny copper pads labeled: J6 – TX, RX, GND, VCC.
His hands shook. He soldered thin wires to the pads. Connected them to the serial adapter. Fired up PuTTY.
The terminal blinked to life.

Bootloader 1.2.1
Press any key to stop autoboot...
He slammed the spacebar.

This was the backdoor. The router’s digital throat, exposed.
He typed:
setenv ipaddr 192.168.1.100
setenv serverip 192.168.1.2
tftp 0x81000000 openwrt-hg658v2-squashfs-custom.bin

cp.b 0x81000000 0x9f020000 0x3c0000
bootm
Each command felt like reciting an exorcism. The terminal spat back hexadecimal affirmations. OK. OK. Done.
Then silence.
The router’s power LED blinked amber for ten agonizing seconds. Leo held his breath. Mira’s voice drifted from the other room: “Did you just kill the Wi-Fi? I’m watching something!”
Then—green.
The LED went solid. The router rebooted. Leo’s laptop, still connected via Ethernet, suddenly pulled a new IP. He opened a browser. Typed 192.168.1.1.
A new interface loaded. OpenWrt – lean, mean, grey and green. No ISP logos. No telemetry. Just graphs, packet filters, and a beautiful, terrifying amount of control.
He configured SQM (Smart Queue Management) – a feature the stock firmware had buried so deep it might as well have been a myth. He set upload to 80% of line rate. Enabled hardware flow offloading.
Then he waited for 8:03 PM.
It came. The microwave hummed. Mira’s Netflix started. Leo launched a speed test.
45 Mbps down. 11 Mbps up.
Ping: 14 ms.
The router didn’t stutter. It didn’t drop. It purred.
Mira knocked on his door. “Hey… the internet feels weirdly fast. Did you do something?”
Leo leaned back, staring at the little black obelisk now running code written by strangers on a forum, held together by hope and Linux.
“Yeah,” he said. “I fixed it.”
That night, he donated €20 to the OpenWrt project. And in a drawer, wrapped in an anti-static bag, lay the original HG658 v2 firmware—a digital poison pill he would never, ever touch again.
Epilogue: Two years later, Leo bought a UniFi Dream Machine. But he never threw away the Huawei. On its side, in faded silver Sharpie, he had written:
“s3rgei was here.”
Installing custom firmware like OpenWrt or DD-WRT on the Huawei HG658 V2 is not currently supported . While older variants like the HG658b/c have limited OpenWrt support, the HG658 V2 uses a proprietary Broadcom or Hisilicon chipset (depending on the region) that lacks open-source drivers .
If your goal is to remove ISP restrictions or add features, you can often "unlock" the router by flashing unbranded official firmware instead. 1. Identify Your Version
Check the sticker on the bottom of your router to confirm your chipset, as this dictates which official firmware you can use: Broadcom BCM63168: Common in Western markets .
Hisilicon SD5610H: Often found in variants like the HG658c V2 . 2. Access the Management Interface Before flashing, ensure you have administrative access. Standard IP: 192.168.1.1 .
Default Credentials: Try admin / admin or admin / HuaweiAdm .
ISP-Specific: For TPG, use admin / admin ; for some Vodafone units, try vodafone / vodafone/admin1234 . 3. Flash Unbranded Firmware (Recommended Alternative)
