A method for protecting firmware being updated is applicable to an electronic device installed with an open operating platform and applicable to a firmware update tool having a preset unlocking password. The method includes an unlocking step and a specific password generating step. In the specific password generating step, the unlocking password is updated according to the difference between product serial number-related information at the point in time of delivery of an electronic device. Although the preset unlocking password in the source code of the firmware update tool is disclosed, nobody other than the electronic product users and the electronic device manufacturers knows the first unlocking password and the second unlocking password. Accordingly, the method provides a security mechanism for the electronic device and the firmware update tool. |
