How to load Eunhasu image to the micro SD card.

Windows OS

Preparation

- Download the latest Eunhasu image file and unzip it. Please note the image file is quite big. To download the Eunhasu image file, please send the serial number of your unit to the email address below: info@sotm-audio.com

- Download the imageUSB utility and unzip it, or try using Balena Etcher as it may work more reliably depending on your system.

- Press gently on the micro SD card in the micro SD card slot on the rear panel of sMS-200 to take it out, and insert it into a micro SD card reader. The micro SD card slot is “push-push type”, so after loading the image file to the micro SD card, you can insert the micro SD card back into the slot. Once it's inserted properly, you will hear a click sound.

- If the file name ends with .gz or .zip, you need to extract it using a separate utility.

- If you are not able to complete the process successfully after following these steps, please check the following video: https://youtu.be/ty_HN2gqJtQ. Some unzip utilities may not extract the files completely, and in some cases, the extraction process may need to be performed twice. The video was created by one of our valued customers. Thanks to HC for sharing it.
