Update the Firmware on the Phone
To update the firmware on the phone:
Download the updated firmware onto your PC.
If you are in a VPN connection, you might need to disconnect from the network
before proceeding so that your PC can communicate directly with your phone for
the upgrade.
Run the executable file for the firmware upgrade (for example, double click
spa50x-30x-7-4-9c.exe). A message regarding upgrading your phone displays.
Click Continue.
Enter the IP address of your phone and verify the address of your PC.
Click OK. The system displays information about your phone firmware and
hardware.
Click Upgrade to begin the upgrade.
Do not disconnect your phone power until the upgrade is complete (the lights on
your phone are no longer blinking).
Click OK to dismiss the status message of the upgrade.
