If your meloki appliance is currently running a Debian 13-based installation, a one-time reinstallation using the provided SDR USB stick is required.

This ensures that the appliance is migrated to the current software platform and remains eligible for future updates and support.

After the reinstallation is complete, you can restore your existing backup and continue working normally.

Factory Reset​

This guide describes how to restore a meloki appliance to its factory default state using the provided recovery media.

Each meloki appliance is shipped with a dedicated Secure Disaster Recovery (SDR) USB stick. The SDR stick contains an automated recovery environment that reinstalls the appliance without requiring manual intervention.
