ISPs use encrypted firmware signatures. The router’s bootloader checks for a digital signature from the ISP (e.g., Vodafone or China Mobile) before installing. A generic ZTE file lacks that signature. Attempting to force it can trigger a "signature verification failed" brick—a permanent brick.
A frequent question on tech forums: "Can I install generic ZTE firmware on my ISP-locked router to remove branding?"
While updating your ZTE router's firmware is generally a smooth process, you may encounter some issues. Here are some common problems and their solutions: zte router firmware

Write this down. You cannot install firmware meant for a different hardware version.
