How do I update my Cubelets to OS 4?

If you already have a Bluetooth Cubelet, then you have everything you need to update!
When you download the new Cubelets App for iOS or Android, connect your Bluetooth Cubelet and follow the in-app instructions that will help you complete the update.
For most users, the update shouldn’t take more than a few minutes. We suggest giving yourself about 5-10 minutes to download the Cubelets App and watch our OS 4 Update instructional video. After that, each Cubelet will take about 20 -30 seconds to fully update before you can snap it off and snap the next Cubelet on. 

Watch the OS 4 Upgrade Tutorial on Youtube for step by step instructions!

Please note that the update process for updating Cubelets from OS 4 to OS 4.3 is different. You can find direction for updating Cubelets from OS 4 to the latest OS 4 release here.
Cubelets OS 4 firmware is not compatible with previous Cubelets operating systems. All OS 4 version are compatible with other OS 4 versions (such as the recent OS 4.3 release). 
You’ll need to upgrade your existing Cubelets if you want to take advantage of the new features or any new Cubelets we add to the Cubelets collection. All Cubelets sold going forward will be running the OS 4.3 firmware and will be unable to communicate with pre-OS 4 based operating systems.

Cubelets not updated to OS 4 will still work and play just the same as they always have, but going forward you will be limited in your ability to add new Cubelets to your collection because new Cubelets running OS 4 will not be compatible with previous Cubelets operating systems.
Don’t worry, if you don’t upgrade your existing Cubelets to OS 4, you’ll still receive the same great product support available to you now. Just let Customer Support know your Cubelets were purchased before the OS 4 update and have not been updated and we will make sure your warranty replacement is compatible.
