Hi all. Just wanted to close this out and share what Devialet advised. After multiple rounds of emails, they suggested a “Rescue Mode” with these instructions:
1. Plug your Phantom to your internet router via an Ethernet cable.
2. Plug your Phantom to a power strip with an on/off button
3. Turn on the power strip for 7 seconds, then off for 3 seconds
4. Proceed to the "on/off" sequence 6 times consecutively and leave it on for 2 hours
5. The Phantom(s) will enter in Rescue Mode and will start downloading the firmware while moving the woofers every few seconds.
Customer service very kindly scheduled a call with me to walk through the steps. And then called me back again 2 hours later after the Rescue Mode was complete. Then walked me through pairing to Spark, then upgrading to DOS2 with Devialet app, and then connecting the already-upgraded Gold with this newly upgraded Gold.
Now my issue is that the already-upgraded Gold is on 2.12.5 and the newly-upgraded Gold is on 2.12.13. And experiencing drop-outs like everyone else who upgraded. A different issue, indeed, but at least this one has been solved!
Thanks to everyone who offered advice!
