Sharing my experience upgrading my 1000 Pro CI.
Downloaded the new firmware ZIP file. Unzipped it to a folder.
Disconnected the power to both Devialets.
Copied the files to both my Master & Companion SD cards, leaving the original configuration files on the SD cards intact.
Only files on each card are new firmware files and old config file.
Inserted both SD cards back into the Devialets.
Turned on the power to both Devialets.
Both Devialets did the upgrade, taking several minutes (the DOS upgrading part takes a long time).
Upgrade on both successful! Press front power button on both units to shut them down.
Power on the Master unit again and both now work normally.
Also tested removing the power from both units, and restoring power. Both power up normally.
