The BlackBerry Bold 9700, released as a successor to the 9000 series, operates on a proprietary Java-based operating system. Unlike modern Android or iOS devices, firmware updates for the 9700 involve a deterministic state machine process managed via the BlackBerry Desktop Manager (BDM) or wireless carrier push (OTA). This paper outlines the architecture of the firmware update, pre-update validation checks, risk mitigation for bricked states, and the post-update radio (baseband) calibration requirements.
