Restoring Your NavVis VLX/MLX Device with an ISO Image

Prev Next

Introduction

In corner cases, when the NavVis VLX / MLX device is experiencing operating system failures and cannot boot correctly, it is then required to flash and restore the system to a specific image.

This procedure describes how the system restore can be done with an ISO image from an external disk.

Download the ISO image file

Contact NavVis Support team (support@navvis.com) with your device’s serial number to get the latest ISO image file. Depending on the serial number, there will be a dedicated version of ISO image provided.

The ISO file will be shared via a Onedrive link.

Create a bootable drive using the ISO image

Prerequisites

  • Hardware

    • VLX: Device’s own SSD as the bootable drive, a keyboard with USB-A connector

    • MLX: A USB-C dongle that can connect a USB drive and a USB keyboard

  • ISO file

  • A computer that can create a bootable USB drive

Creating the bootable drive

There are various tools that can create a bootable drive from an ISO image. For example, Ubuntu has its own tool from the native system named “Startup Disk Creator“.

The tool that we recommend is called “balenaEtcher“: https://etcher.balena.io/ . This is a cross-platform tool that can be used on Windows/macOS/Linux.

The bootable drive creation is quite simple; the balenaEtcher tool will guide you through the following steps:

Example of using balenaEtcher on macOS

The following steps show how a bootable drive is created in macOS.

A similar procedure also applies to Windows/Linux.

  1. Select Flash from file.

  2. Select the downloaded VLX/MLX ISO file.
