Migration DOS 2 and Phantom I (Premier)

On November 4, our customers will be offered the possibility to update their Phantom I (Premier) and Dialog products to the new DOS2 operating system.

Before engaging the migration, please have a quick overview of the article here to decide on migration.

The migration can take up to 20 minutes per device. Please make sure you have spared enough time to perform the migration in full.

1. What is DOS 2?

DOS stands for Devialet Operating System. It's the software that runs in the products. Five years ago, Phantom I (Premier) was launched, and it came with DOS1, the first version of our software.

Following our customers' issues and requests, we decided to move forward with a new version (DOS2).

DOS2 already runs on Phantom Reactor since November 2018, and we plan to run it on all our products eventually. Phantom I's turn was on November 4, 2019.

Note: Classic Phantom Premier owners, this migration will increase the power of your Phantom(s) from 1200W to 2000W and sound level from 101 dB to 103 dB.

2. Why should I migrate my system to DOS 2?

Of course, it's not an obligation to move to DOS 2. However, we highly recommend this migration for customers with stability issues. DOS2 brings more flexibility in the ways multiple products communicate with each other. Setup and stereo pair creation are more accessible than ever (of course, DOS2 also brings back regular software updates to the Phantom I family).

Note: In Devialet App and DOS 2, we decided not to embed online music platforms such as Deezer, Qobuz, or Tidal but considered providing you the best and easiest access to streaming protocols. Thus, Deezer, Tidal, or Qobuz won't be integrated into the Devialet App.

Note: Our prior software operating system did allow stereo setup with a mixed version of our products (for example, set a Phantom Silver on Left and a Gold on the Right in Spark). This is not possible with DOS2. If you own a mixed setup (different models of Phantom in the same room), please note that you won't be able to set them up in Stereo for the moment. However, you can still play the same content on both Phantom if you group them using the multi-room feature. Please feel free to reach your customer service for additional information.

4. What are the different phases I will see during the migration?

The migration stands with four different phases:

Phase 1: Identification of products (1a), Selection of products (1b) & firmware download on your phone (1c).
Phase 2: Pushing firmware on the product memory.
Phase 3: Migration part.
Phase 4: Product setup with the Devialet app.

NB: These steps need to be repeated on each product you want to migrate.

NB: Your Dialog can be migrated as well, but do its update at the very end of the process and privilege Phantom I (Premier) migration at first. Your Dialog will still provide one more optical input on your system and could still be the Airplay enabler of your system if it is only composed of Bluetooth capable devices.

Phase 1a - Products identification

Search into the Android Store or App store for the Devialet app application.
Install the app
Open the app
Select the top wheel and click on "Add a new product."
Let the system search for Phantom devices connected to your network.

NB: To migrate, your Phantom I (Premier) and Dialog need to be on the latest DOS1 firmware update (1.14). If not, the Devialet app will ask you to go back to Spark and update your product before allowing the migration.

NB: To identify the product, the Devialet app will look at all Devialet products connected to your domestic network. So please ensure the device you are looking to update is set up with Spark before this migration.

Phase 1b - Product selection.

Once your product is discovered, the carousel will appear.

Please wait for the list to be complete (Dialog may appear quicker than Phantom I (Premier) because it is wired in ethernet.)
Swipe from right to left to find out the correct product you want to update.
Select the product you want to update (serial number is visible on the carousel for this reason).
Read and accept the changes in new features and the main differences between your prior system and the new app's features.

Phase 1c - Firmware download

Once you have pressed the "Download Update now" button, the downloading phase will start.

The timing behind this phase depends on your internet connection.

Note: It's important to avoid switching off your mobile during this part of the migration, nor putting the app in the background. The app will prevent your mobile phone from locking automatically during this phase.

Note: 200 Mo is necessary for downloading the firmware to your mobile. The Devialet app will inform you before downloading if there is not enough space on your phone.

Phase 1b - Product selection

Phase 1c - Firmware download

Phase 1c - Firmware download - free space on your mobile

Phase 2 - Copying firmware to your product

This phase starts once the firmware has been downloaded to your mobile.

Devialet app will ask you to accept the operating changes, as no rollback will be possible afterward.

Select "I Understand and Accept. Proceed to update."
Press the "Install Update now" button.
The app will then push the firmware to your speaker. It can take time.

NB: This is a critical part of the migration. Please make sure you do not switch off your phone or put the app in the background.

Phase 2 - Pushing firmware to your Phantom I (Premier)

Top

Phase 3 - Migration

NB: Please do not unplug your Phantom I (Premier) as this part is critical for the product.

This phase will display quotes about music on the top part of the screen and a percentage of the migration evolution.

The most critical part is about the first 30%, then you can put your mobile in standby mode and let the Phantom migrate by itself.

NOTE: During this phase, your Phantom's woofer will make regular moves, so do not do anything until you hear the DOS2 booting sound design

In case you did not hear any sound and the app displays a "failed" message, please wait a bit. Your device may still move to the new OS.

NOTE: To confirm you've moved your Phantom to DOS 2, make a single press on the back button of Phantom. You should hear the Setup sound

Phase 3 - Migration

Phase 4 - Setup your Products!

NB: the below operations should be done for all devices you need/want to move to DOS 2.

When you're done migrating all the products, it's time to set up.

To do the setup, please follow the steps below:

Open Devialet App
Press on the setting icon on the top left of the main screen
Select "Add products."
The Devialet app will search for Phantom products.
Once the app finds all your products, the Carousel will appear.

Follow the steps in the app.
