Firmware is the built-in software that controls:
Firmware version format typically looks like:
Bxx (e.g., B13, B15, B16, B19)
or
Cxx (e.g., C12, C15)
or
V1.0.0-xxxx.xx
Running outdated firmware isn’t just about performance—it’s dangerous. The ZTE MC801A has had several high-profile CVEs (Common Vulnerabilities and Exposures):
If your firmware is older than V1.0.0B11 (released March 2023), you are vulnerable to these exploits. Update immediately or isolate the router on a guest network.
Example output:
BD_THREEV1.0.0B09 → Three UK firmware.

The ZTE MC801A Go to product viewer dialog for this item. is one of the most popular 5G indoor routers globally, known for its high-speed performance and reliability. However, its performance is heavily tied to its firmware, which can vary significantly depending on whether the device is unbranded (generic) or tied to a specific carrier like Three, Vodafone, or Elisa.
This guide covers everything you need to know about managing, updating, and troubleshooting the ZTE MC801A 1. Understanding Firmware Variants ZTE MC801A
uses different "branches" of firmware based on its original region or carrier. This is why some users have features (like bridge mode or manual band selection) that others do not.
Branded Firmware: Carriers like Three Ireland or Vodafone often lock certain settings to ensure network stability.
Generic/Global Firmware: Generally offers the most freedom, including advanced networking features and frequent security patches.
Security Vulnerabilities: It is critical to keep firmware updated to protect against known exploits. For instance, specific versions like mc801a_elisa3_b19 have tracked security profiles on CVE Details. 2. How to Check and Update Firmware
Updates are typically delivered Over-The-Air (OTA). To check for an update: Connect to your router via Wi-Fi or Ethernet. Open a web browser and go to 192.168.0.1 (default IP).
Log in using the password found on the sticker at the bottom of the device. Navigate to Advanced Settings > Update. Click Check for Updates. 3. Key Features in Recent Updates
Newer firmware versions often unlock or improve the following: Bridge Mode: Allows you to use the
strictly as a modem while using a more powerful third-party mesh system or router for Wi-Fi.
Band Locking: A community-favourite feature (often accessed via third-party scripts on GitHub or Reddit) that lets you force the router onto a specific 5G or 4G band for better stability.
Signal Diagnostics: Improved "Standard Check" tools to help you position the router for the best 5G reception. 4. Troubleshooting Firmware Issues
If your router becomes unstable after an update or if you cannot access the interface, a Factory Reset is the first step:
The Reset Method: Locate the small "Reset" hole on the back or bottom. Use a pin to press and hold it for about 3 seconds until the LED lights cycle. This will revert all settings (including passwords) to the defaults listed on the device sticker Three Support. 5. Community "De-branding" and Custom Scripts
Many enthusiasts use custom web scripts to unlock hidden menus in the ZTE firmware. These scripts can often toggle features like: Cell Locking: Manually selecting a specific cell tower.
Antenna Selection: Choosing between internal antennas or the TS9 external ports.
Detailed Metrics: Viewing RSRP, RSRQ, and SINR values in real-time.
Are you looking to unlock a specific feature like Bridge Mode, or are you trying to fix a connection issue with your current firmware?
Technical Overview: ZTE MC801A Firmware Architecture and Management The ZTE MC801A
is a prominent 5G Indoor CPE (Customer Premises Equipment) powered by the Qualcomm Snapdragon X55 chipset. Its firmware is the critical software layer that manages network connectivity, hardware interfaces, and user security. Understanding its structure is essential for network optimization and maintenance. 1. Firmware Structure and Core Components
The firmware of the MC801A is based on a customized Linux distribution designed for high-performance routing. Key components include:
Modem Firmware: Manages the Snapdragon X55 baseband, handling 5G Sub-6GHz and 4G LTE frequency bands, carrier aggregation, and signal modulation.
WebGUI (User Interface): The HTTP-based management portal that allows users to configure APN settings, Wi-Fi parameters, and security features.
Kernel and Drivers: Low-level software that facilitates communication between the OS and hardware components like the Wi-Fi 6 (802.11ax) radio and Ethernet ports. 2. Versioning and Regional Customization
Firmware versions for the MC801A vary significantly based on the distribution channel:
Global/Generic Versions: Often carry the "B" prefix (e.g., BD_ZEAM801AV1.0.0B07). These are typically unlocked and support a wide range of global bands.
Carrier-Specific Versions: Customized for providers like Three (UK), Telekom (Germany), or STC (Saudi Arabia). These often include:
Network Locks: Restricting the device to specific SIM cards.
Custom WebGUI: Branded interfaces with restricted advanced settings (e.g., hidden antenna selection or band locking).
OTA (Over-The-Air) Update Servers: Pointing to carrier-hosted servers rather than ZTE’s generic infrastructure. 3. Firmware Update Mechanisms
The device utilizes several methods for software maintenance:
TR-069 Protocol: A standard for remote management, allowing ISPs to push updates and configure devices automatically.
Manual WebUI Update: Some versions allow users to upload a .bin or .zip firmware file directly through the "Advanced Settings" menu.
ZTE Download Tool: A specialized Windows-based utility used for "de-branding" or recovering "bricked" devices via a wired connection. 4. Advanced Modifications and Community Developments
Technical communities often seek to modify MC801A firmware to unlock hidden capabilities:
Band Locking: Enabling the ability to force the modem onto specific 5G or LTE frequencies to improve stability.
Bridge Mode: Bypassing the internal router to use the MC801A strictly as a modem for third-party mesh systems.
Cell Selection: Manually choosing the strongest cell tower rather than relying on the modem's default logic. 5. Security and Stability Considerations
Firmware updates frequently address vulnerabilities and performance bugs. Key areas of focus include:
Thermal Management: Logic that throttles speeds if the Snapdragon X55 exceeds safe operating temperatures.
WPA3 Implementation: Updates often improve the stability of WPA3 wireless security protocols.
IPv6 Compatibility: Ensuring seamless transition and dual-stack support across different global carriers.
Managing firmware on the ZTE MC801A is crucial for maintaining a stable 5G connection, as different versions can significantly impact features like Bridge Mode and gaming connectivity. Current Key Firmware Versions & Known Issues Firmware updates for the ZTE MC801A
are often pushed automatically by network providers (such as Three UK or EE), but they have been known to cause specific issues:
Firmware B15: Users have reported significant issues with this version, specifically an inability to connect to the PlayStation Network (PSN) and various streaming platforms, even when signal strength is high.
Firmware B12: This update famously "broke" Bridge Mode for many users, causing the router to issue incorrect IP addresses to connected downstream routers.
Stock Firmware: Official "Stock ROM" flash files and flashing tools (like QPST Tool) are sometimes used by advanced users to unbrand or recover devices, though this carries a risk of bricking the unit. Managing Your Firmware
Checking Version: Access your router's web admin interface by navigating to 192.168.0.1 in your browser. The login password is typically found on a label at the bottom of the device.
Automatic Updates: Most units are set to update automatically. If you are experiencing the "Bridge Mode" bug, you may need to disable Bridge Mode and switch back to "Wireless Broadband" mode for a stable connection.
Factory Reset: If a firmware update causes instability, a factory reset can sometimes clear configuration conflicts. Use a SIM eject tool to hold the RESET button for about 10 seconds until the lights cycle.
Unlocking: If you have firmware from a specific carrier and want to use a different SIM, you may need an unlock code, which can be applied through the web interface after inserting a non-supported SIM. User Perspectives on Firmware Performance “I have the 5G ZTE MC801A
