(also known as the Huawei 4G Router Prime) is a popular Cat6 LTE router often distributed by internet service providers like Globe or Optus. The firmware is the critical software layer that manages its modem performance, security, and carrier-specific features. Current Firmware Ecosystem
As of late 2025, there are two primary paths for managing this device's firmware: Official Carrier Updates
: Most B622-335 units are "locked" to a specific carrier. Updates are delivered OTA (Over-The-Air)
. These updates typically focus on security patches and network stability but often restrict features like band locking or third-party SIM usage. Custom/Debranded Firmware
: There is a significant community interest in "debranding" these routers. Debranded firmware removes carrier logos and, more importantly, unlocks the Manual Band Locking
: Forcing the router to use specific frequencies (like Band 3, 7, or 41) to improve speeds. Antenna Selection : Manually toggling between internal and external antennas. Bridge Mode
: Disabling the router's NAT to use it strictly as a modem with a high-end mesh system. Key Version Indicators
While version numbers vary by region, firmware for this model generally follows the Huawei naming convention (e.g., Target Versions : Users often seek versions that allow for Cell ID locking
, which is vital for users in congested areas who want to stay connected to a specific, less-crowded cell tower. Risk of "Brick"
: Attempting to flash firmware meant for a different sub-model (like the B612 or B535) will likely result in a "brick," rendering the device unusable. Performance & Security B622-335 Firmware
: Newer firmware versions address "WiFi drops" and overheating issues reported in early stock versions.
: Official firmware includes WPA3 support in some regions and patches for vulnerabilities like the "FragAttack" flaws. VoIP/VoLTE
: Some firmware versions enable or disable the RJ11 telephone port functionality, which is a major pain point for users wanting to use the router for home phone services. How to Check Your Current Version Connect to your router’s WiFi. Navigate to 192.168.254.254 (for Globe units) or 192.168.8.1 (standard Huawei). Log in and go to Advanced > System > Device Information Are you looking to a specific carrier unit or simply trying to fix a connection issue with your current setup?
The Huawei B622-335 firmware (often branded as the Soyealink 4G+ CPE 3) serves as the critical operating system that manages the device's 4G+ connectivity, Wi-Fi 6 (AX1500) distribution, and security protocols. Core Functionality and Performance
The firmware is designed to optimize the Balong chipset, enabling plug-and-play 4G+ speeds of up to 400 Mbps download and 75 Mbps upload. It manages the dual-band Wi-Fi AX1500 signal, which allows up to 64 devices to connect simultaneously across the 2.4 GHz and 5 GHz bands. Key software features include:
Networking Protocols: Support for IPv4/IPv6 dual stack, multi-APN, and VPN tunneling/penetration.
Security: Integrated firewall, PIN protection, and MAC address filtering to safeguard internet activities.
Voice Services: Support for VoLTE, VoIP, and Circuit Switch (CS) voice modes via the RJ11 telephone port. Version Information Known software versions for this specific model include: 11.0.5.51(H470SP20C314) (Validated March 2023). 11.0.3.1(H380SP1C00).

B622-335 if you provide a device photo or vendor name?binwalk or strings?The Huawei (Soyealink) B622-335 is a 4G+ LTE Cat6 router that supports speeds up to 400 Mbps. Keeping your firmware updated ensures better security, performance, and bug fixes. Preparation
Locate Login Credentials: Find the default IP address (usually 192.168.8.1), username, and password on the sticker at the bottom of the device.
Stable Connection: Connect your computer directly to a LAN port using an Ethernet cable for the most reliable update.
Power Warning: Never power off the router or disconnect cables during an update, as this can cause permanent hardware damage. Method 1: Using the Web Interface (Recommended)
Access the Admin Page: Open a web browser and enter the router's IP address (e.g., 192.168.8.1). Log In: Enter your administrator username and password. Navigate to Updates: Go to More Functions > Manage Updates.
Check for Updates: Click Check for updates. If a new version is found, click Update or One-click update to begin.
Enable Auto-Update: Toggle Auto-update on and set an update time (e.g., 3:00 AM) so the router stays current automatically. Method 2: Using the HUAWEI AI Life App
Connect to Wi-Fi: Ensure your smartphone is connected to the B622-335's Wi-Fi network.
Open AI Life: Launch the HUAWEI AI Life App and select your router. Access Update Settings: Go to Updates or Devices > Updates. (also known as the Huawei 4G Router Prime)
Install Update: If a new version is available, follow the on-screen prompts to download and install it. Troubleshooting & Manual Updates Huawei B622-335 | 4G+ modem Router Review (Soyealink)

Manufacturers release firmware updates for three primary reasons. Ignoring them puts your entire deployment at risk.
The manufacturer’s 2025 roadmap indicates that B622-335 Firmware will be migrating to a unified codebase supporting Containers (Docker light) and edge AI. Version 5.0 (expected Q1 2026) will drop support for plaintext HTTP and require certificate-based authentication for all web interfaces.
If you are still running version 1.x or 2.x, plan your upgrade path now. The security and performance delta is non-negotiable for any internet-connected device.
Symptoms: Pings to the device fail for 2–3 seconds, recurring like clockwork.
Cause: A memory leak in B622-335 versions 2.8.0 through 2.8.4 affecting the ARP cache.
Fix: Upgrade directly to version 2.9.0 or newer. If that is impossible, disable “Smart ARP” in the advanced settings.
The Huawei B622-335, a lesser-known Outdoor Unit (ODU) in the LTE CPE market, serves as a robust solution for rural broadband deployments. While the hardware is praised for its weather resistance and integrated antenna design, the firmware governing the device remains a point of contention for advanced users and network administrators. This article examines the B622-335 firmware architecture, analyzes the implications of version locking, and explores the technical challenges surrounding customization and firmware extraction.
