It cannot completely eliminate the possibility of device bricking. Always ensure your device has a complete backup of the original firmware and configuration before attempting any flashing operations. In some cases, even with the correct firmware, the device may fail to complete the upgrade, requiring additional manual interventions such as repackaging the shell completion file.

A firmware flash tool is specialized software designed to write or "flash" new system instructions (firmware) directly onto the hardware's non-volatile memory. For Huawei ONTs, these tools allow users or technicians to update the operating system, fix bugs, or restore a "bricked" device that no longer boots correctly. Common Tools Used

Official documentation primarily focuses on upgrading firmware via an Optical Line Terminal (OLT) or through the device's web management interface. Upgrade from OLT Side : This guide details the procedure for upgrading ONT firmware via OLT
