Do not install firmware from B593s-22 onto a B593s-82. Even if the file name looks similar, the bootloaders differ.
To upgrade the firmware on your Huawei LTE CPE B593 (such as the B593u-12 or B593s-22), follow this process to ensure improved stability, security, and potential new features like IPv6 support. Preparation: Before You Begin Identify Your Model
Secondly, security is a paramount concern that necessitates proactive firmware management. The B593, like all routers, is a potential entry point for malicious actors. Older firmware versions may contain known vulnerabilities in the web-based administration interface, Universal Plug and Play (UPnP) services, or the Wi-Fi encryption protocols (WPA2). As cybersecurity researchers discover exploits, Huawei releases patches to close these gaps. Without a firmware upgrade, a B593 router remains exposed to threats such as DNS hijacking, credential theft, or incorporation into a botnet. Given that many users deploy the B593 in sensitive environments like small offices or home payment systems, neglecting firmware updates compromises the integrity of the entire connected ecosystem.
The router will automatically reboot once the upgrade completes. This may take 3–5 minutes. The status LEDs will cycle. Wait until the power and internet LEDs stabilize.

This is the safest and easiest method if you can access your router’s web management interface.
Old firmware often falls back to 3G. New firmware allows band locking.
Upgrading the firmware on a Huawei LTE CPE B593 is a straightforward but high-stakes procedure that demands careful preparation. By identifying the correct model, obtaining trusted firmware, ensuring a stable power supply, and following each step without interruption, users can significantly enhance their router’s security, stability, and performance. While the device is aging, a well-maintained B593 can continue to provide reliable 4G connectivity for years to come. Conversely, a rushed or ill-informed upgrade can brick the device permanently. Therefore, treat the firmware upgrade process with the respect it deserves: research thoroughly, prepare meticulously, and execute patiently. In doing so, you extend the useful life of a classic piece of networking hardware. Do not install firmware from B593s-22 onto a B593s-82
If the CFE Web Server method fails, other professional (or semi-professional) software tools are available that can communicate with the B593's bootloader at an even lower level to force a firmware write. These include tools designed for Broadcom-based devices or universal flashing utilities.
While standard updates preserve user configurations, some firmware variations perform a complete factory wipe. Save your current network profiles, custom APN parameters, and Wi-Fi security passphrases to a local text file.
The CPE WAN Management Protocol (CWMP) is often used by ISPs to manage routers remotely. You can trigger an update this way by choosing Home > Update and clicking on CWMP Update .

This is often a sign of corrupted firmware, using the wrong file for your router model, or a problem with the USB port connection.
Upgrading the firmware on your Huawei LTE CPE B593 4G router is a fundamental maintenance practice that enhances security, stability, and performance. While the process can seem daunting, following this step-by-step guide—from backing up settings to using the correct upgrade method—will ensure a smooth and safe update. Always double-check your router model and only use trusted firmware sources. With a little patience, you can keep your B593 running at its best for years to come.
This error occurs if you try to upload firmware meant for a different B593 hardware version, or if the file is corrupted. Double-check your exact model code (e.g., B593s-22 vs B593u-12) and download a fresh copy of the file. Cannot Access Dashboard After Upgrade
