Update (Nov 3, 2020): Wireless update system is back up now. Let us know if you run into any issues:
— Archive ----
All,
Our wireless update (FOTA) system is down. So any new phones (or replacement units) might not get the SW6 or SW7 update automatically.
Please check your Build number at Settings > System > About > Wireless update. If your Build starts with Teracube_S1_05 (shipping version), then your battery and phone performance will not be good.
Recommended Upgrade
Please follow the Manual steps to install SW6 at the very least. Once you have SW6, you can also optionally upgrade from SW6 to SW7 manually.
We are working hard to get the wireless update system fixed.
