Updating the firmware of your CycloDS Evolution is very easy.
You will need to download the firmware update from the Team Cyclops site.
Then Umcompress the archive and copy the .evo file to the root of the Micro SD. That simply means that the only file that you need to drag is a file ending .evo (do not copy folders) and drop it onto a memory card.
Load your CycloDS Evolution and it will begin the firmware update automatically.

One question: After I have installed the update, I can simply remove the evo file from the memory card? Thanks for answering! Best regards from Zurich. Salut, Pascal.
Pascal: Do NOT remove the.evo file, otherwise the card will not work

Try using the none beta version.
Beta, means that the firmware is still in testing phase
