If the update were to fail, the Mac will power off leaving the optical drive open, allowing you to insert the firmware restore disk and power it back up to restore its old firmware. When updating the firmware, the MacPro5,1 opens its optical disk drive. To update the EFI firmware in a MacPro5,1, you will therefore have to download the latest full macOS installer app from the App Store, run that, and when prompted hold down the Power button on shutdown to trigger the ‘flash’ process.
