6.1 ISP Locking

The primary risk when flashing firmware is the Hardware ID (HWID) check. The bootloader verifies if the firmware image matches the specific ISP hardware variant. Flashing a "generic" ZTE firmware onto an ISP-locked B866V2 will typically fail or render the device inoperable.

3. Obtaining Firmware

Official firmware is not distributed directly by ZTE to end users. Common legitimate sources:
