The Huawei HG658 v2 is a dual-band ADSL2+/VDSL2 router often provided by Internet Service Providers (ISPs) like TalkTalk, Plusnet, and others across Europe. On paper, it’s a capable device: 802.11n Wi-Fi, Gigabit Ethernet, and a built-in VDSL modem. In reality, the stock firmware is notoriously locked down, buggy, and lacking in features.
This is where Huawei HG658 v2 custom firmware comes into play. Flashing a custom firmware can transform this aging gateway into a powerful, flexible routing machine. However, the process is fraught with risk and specific requirements.
In this article, we will explore what custom firmware exists for the HG658 v2, the benefits, the dangers, and a step-by-step guide to the most popular option: OpenWrt.

firmware flashing or HG658_V2_Flash_Firmware to flash the custom firmware onto your device.Resources
Some useful resources to get you started:
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)
If your ISP has "crippled" the device, you can sometimes flash an generic Huawei or O2 firmware to unlock all menu options . Modem Configuration Guide HG658 - TPG
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 huawei hg658 v2 custom 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
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.
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.

This was the backdoor. The router’s digital throat, exposed.
He typed:

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. Unlocking the Potential: The Ultimate Guide to Huawei
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.”
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
