  • Hardware ID Matching: The updater will read the LCD panel ID and hardware revision from the bootloader. If the firmware package does not match the specific hardware variant, the update is aborted with a clear error message: "Error: This firmware is for [Panel ID], but your device is [Panel ID]."
  • A/B Partition Logic: Implement a backup recovery mode. If an update fails mid-way, the system will automatically boot into a minimal "Safe Mode" allowing the user to retry the update via USB without needing a PC connection.
