If an update gets stuck, fails to start, or your router becomes unresponsive, follow these steps:

Is your router or carrier-branded (Three, EE, Telstra, etc.)? What is your current firmware version number?

What is currently on your router (e.g., Three, Vodafone, generic)? What specific feature are you trying to unlock? What operating system version is your computer running?

: Updates may unlock or refine features like Bridge Mode or improved 5G band selection.

If a new version is available, select to download and install it.

Wait 1–2 weeks after a new release to see if other users report major bugs. Avoid beta firmware unless you’re troubleshooting a specific issue.

Keeping your ZTE MC801A firmware updated is the best way to secure your network and guarantee maximum 5G speeds. For most users, the automatic OTA update feature inside the web dashboard is perfectly adequate. However, if you are looking to unlock hidden features or escape carrier restrictions, exploring local manual updates or de-branding might be worth the effort. Always remember to back up your router settings before making any major software changes!

Modifying internal software via unofficial tools instantly voids your warranty.

If your router is bricked (won't boot, power light flashing red), you need the TFTP recovery method. This is advanced.
