How to update the Critter & Guitari Organelle S

Download the latest OS image from critterandguitari.github.io/cg-docs/Organelle/og_sms2/. Use Balena Etcher (balena.io/etcher) to flash the image to an 8 GB+ microSD card — this will wipe the card, so back up patches first via the web interface or a USB drive. Remove the microSD from the slot on the back of the Organelle S, flash the image, reinsert, and power on. Verify the OS version at Settings > Info. The Organelle S shares its OS with the Organelle M and S2 models.

Just for reference. For complete and up-to-date instructions, always refer to the manufacturer's official firmware page.
