Updating Nucleus

Once your Nucleus is powered on, make sure it's completely up to date before moving forward. The steps below walk you through updating your Nucleus firmware and Roon Server software.

Updating Nucleus Firmware

Update the firmware when you first set up your device, and keep it updated as new releases become available. There are two methods to do so.

Update Nucleus Firmware from the Web Administration Interface

1. In the Roon app, go to Settings > Setup.
   
2. Next to Find Roon OS, click Find. A window appears listing all Roon OS devices on your network.
   
3. Locate your Nucleus and click its IP address. This opens the Nucleus Web Administration Interface.
   
4. Under Operating System, click Reinstall.
   

Updating Nucleus Firmware from Settings > About

You can also update your Roon OS firmware from Settings > About in the Roon app. It appears alongside updates for Roon and Roon Server.

Updating Roon Server
From any device connected to Roon, go to Settings > About. Available updates are listed for each device. Click the update to install it. If the update has already been downloaded, you'll be prompted to relaunch.

Update Settings

Roon offers three options for handling updates.

These options don't appear on mobile remotes.

1. Automatically install all updates (Recommended): Roon downloads every update as it becomes available. This is the best way to stay on the latest version and get new improvements first. Once an update installs, you're prompted to relaunch the app.
   
2. Automatically install bugfix and other minor updates: Roon installs minor maintenance releases automatically. You're asked before any major update downloads. Major updates generally include new functionality or bigger changes.
   
3. Ask before downloading any updates: Roon doesn't download updates automatically. When an update is available, a notification lets you choose whether to install it.
   

Downgrading

Downgrading Roon isn't supported. It can cause database, remote, and cloud compatibility issues.
