If your router software does not allow you to turn off updates, you can use a custom DNS service (like NextDNS) to block ZTE's firmware update servers. If you need help with your specific router, tell me: Which carrier logo is printed on your router? What is your current firmware version string ?
Most units receive this update automatically. To check manually:
In late 2023 and early 2024, security researchers identified several vulnerabilities in the ZTE MC888 web interface (WebUI). zte mc888 firmware patched
If you were using band locking because your signal strength fluctuates wildly, consider hardware modification instead of software modification. The ZTE MC888 features TS9 external antenna ports. Attaching a high-gain directional outdoor antenna can naturally stabilize your connection to the best tower, reducing the necessity for software-enforced cell locking. Final Verdict: Prevention is Key

The ZTE MC888 is a family name used for compact LTE/5G CPEs and USB/CPE modems produced by ZTE and OEM partners. Devices in this class are deployed by carriers and consumers to provide mobile broadband (home gateways, small business routers, USB modems). They generally run embedded Linux (often OpenWrt derivatives or vendor customizations) with services for web management, PPP/WWAN, NAT, DHCP, DNS, and vendor-specific features (remote provisioning, TR-069, firmware update).
The “firmware patched” keyword encompasses a spectrum of techniques, from simple script injections to full OS replacements. The most common and accessible methods include: Most units receive this update automatically
The landscape of patching the ZTE MC888 is a cat-and-mouse game. Manufacturers like ZTE are making devices increasingly difficult to modify by locking bootloaders and enabling secure boot. This means that many of the simple command-line tricks of the past no longer work.
For the more technically inclined, a deeper level of control is possible by reverse engineering the router's internal API (Application Programming Interface). This is the method that approaches the idea of a "patched firmware" most closely, as it involves creating custom tools to interact with the router's internal functions programmatically.
Easily disable the router capabilities to use the MC888 strictly as a modem paired with high-end mesh Wi-Fi systems.
