    If you have a Windows XP or 7, this will place the upgrade tool and USB drivers into the C:\Program Files\Iridium\9555 directory.

    If you have Windows 8 or 10 you will have to download the USB drivers here:

    1. Unzip the drivers archive.
    2. Execute the Iridium Handset USB Driver Installer and follow the instructions.

  2. . Prior to performing the upgrade complete the following:
    • Disable Bluetooth on the PC running the upgrade
    • Remove the SIM card from the handset and install the handset battery
    • Turn the handset on
    • Ensure that the battery is fully charged or a charger is connected to the handset

  3. Connect the handset to the PC using a USB cable.
    • If the handset is being connected to this PC for the first time, or to a USB port that has not been used before, the driver will be installed automatically. If this is the case, wait for Windows to show the "New Hardware Installed" notification before proceeding.
    • If Windows is unable to automatically locate the USB driver, it can be found at C:\Program Files\Iridium\9555\USB\VCOMPORT.

  4. Run the upgrade installer application.
    • A shortcut to this application should be available in the Start Menu in the Iridium 9555 Software Upgrade folder.
    • The target of the shortcut is C:\Program Files\Iridium\9555\Upgrade_Tool\ Iridium 9555 Software Upgrade.exe

  5. Follow instructions presented by the upgrade tool user interface

    • During the upgrade process the handset will display various information on the screen, including “Upgrading…”
    • At times the handset screen may go completely blank.
    • Do not disconnect the handset or press any keys while the upgrade is in progress.

  • The handset will be rebooted into a USB standard DFU (Device Firmware Upgrade) mode during the upgrade. The DFU driver will be installed if the PC has never been used with a handset in DFU mode before. If Windows is unable to automatically locate the USB DFU driver, it can be found at C:\Program Files\Iridium\9555\USB\DFU.

  • If the Upgrader tool shows no handset found, check if your phone USB drivers are installed and if your phone is correctly plugged in. If your phone is connected correctly, it should display USB cable connected when plugged.
