Most HG8145V5 units distributed by ISPs (such as Airtel in India, Oi Fibra in Brazil, Viettel in Vietnam, or various Chinese telecoms) are not "hard locked" in the traditional cellular phone sense. However, they are generally configuration-locked to the ISP's specific network standards. Many ISPs whitelist the device's unique serial number on their OLT (Optical Line Terminal). In this scenario, using an HG8145V5 from "Provider A" on "Provider B's" fiber network may fail unless the serial number is manually cloned or updated in the new ISP's backend system. As one technician noted on a broadband forum regarding the HG8145V5, "Most likely there is no locking, but the operator would need to whitelist or allow the device to register with the OLT. Mostly serial number based."
Navigate to Network > Broadband Settings or WAN Application . Look for the TR-069 management profile and disable or delete it. This prevents your ISP from remotely updates the firmware and locking you out again.
