Updating the S-4 OS
How to Install and Update the S-4 Operating System
Step-by-Step
Download the latest S-4 OS update file. Make sure to not unzip the downloaded file.
Connect the S-4 to the computer using a USB-C or USB-C to USB-A cable (depending on computer).
Enter USB Mass Storage Mode on the S-4.
Drag and drop the update .zip file into the root folder of the S-4 (the top level of the drive, not inside any other folder).
Use the computer’s eject function to disconnect the S-4.
Tap [CONFIG], go to SYSTEM menu.
Select INSTALL UPDATE to install the update.
When the S-4 has completed the installation of the OS, the system will reboot and the update file will automatically be removed from the device.
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 S-4.
When the update is complete, enter USB Mass Storage Mode to transfer any user samples, recordings and projects back on to the S-4.
