Hi Eugene and Ville,

I pushed the beta apps to production yesterday, you should be able to get the latest version by simply visiting the App Store/Play Store.

Eugene: For your reference, the latest firmware version is 1470628829. SD card reliability has increased substantially over the last few months of firmware development. The new support wiki also has more information on the firmware update process if you have any issues. I hope the update fixes the problem, please let me know how else I can help.
