# Update device software

Use MK.IO to inspect and update the software running on a MediaKind Beam device. When the subscription supports software updates, available versions appear on the device's **Software** panel.

1. In MK.IO, open the project that contains the device.
2. Go to **Devices**, then select the device.
3. In the **Software** panel, use the version menu to preload an available bundle or deploy a downloaded bundle.

For automation, use the [Software and updates API Guide](/api-guides/how-to/fleets/software-and-updates).

MK.IO provides the following functions:

- View the current software bundle version.
- View the bundle available for rollback.
- View the bundles downloaded and ready to deploy.
- Download a bundle and monitor its progress.
- Switch the device to a downloaded bundle.
- Roll back to the previous bundle.

> **Info:** **Software bundles**
>
> MK.IO updates the full operating system and software stack through software bundles and the dual-bank mechanism in Beam devices. If the selected version matches the version in the second bank, the device performs a rollback instead of an upgrade or downgrade.

Beam devices can store multiple software bundles for deployment. Storage for bundles is limited, so the device automatically deletes older bundles when a new bundle needs more space.
