Ensure Windows Driver Signature Enforcement is turned off if you are installing legacy Qualcomm or ZTE device drivers.

Because this framework operates with high-level system privileges (root access), it requires stringent security validation to prevent malicious actors from hijacking the update process. What Does "Verified" Mean in this Context?

When a device logs or displays the status during a software update cycle, it means the framework has successfully completed a series of rigorous cryptographic handshakes. ZTE utilizes a strict "Chain of Trust" root-of-trust mechanism.

When a device displays or requires this verification, it means the operating system has passed rigorous cryptographic checks established by ZTE and its operating partners. Core Components of the Framework
