Updating the S4 OS

How to Install and Update the S4 Operating System

---

Step-by-Step

1. Download the latest S4 OS update file. Make sure to not unzip the downloaded file.

2. Connect the S4 to the computer using a USB-C or USB-C to USB-A cable (depending on computer).

3. Enter USB Mass Storage Mode on the S4.

4. Drag and drop the update .zip file into the root folder of the S4 (the top level of the drive, not inside any other folder).

5. Use the computer’s eject function to disconnect the S4.

6. Tap [CONFIG], go to SYSTEM menu.

7. Select INSTALL UPDATE to install the update.

When the S4 has completed the installation of the OS, the system will reboot and the update file will automatically be removed from the device.

Plugging in an external USB Flash Drive with an S4 update .zip file will automatically update the S4.

Updating from v1.x to v2.x

Updating from v1.x to v2.x requires you to remove all user data from disk. A prompt will guide you through the process - no data will be deleted automatically.

The v2.x installation cannot proceed if user samples, recordings, or projects remain on the S4.

When the update is complete, enter USB Mass Storage Mode to transfer any user samples, recordings and projects back on to the S4.
