Dear customer,
We are so sorry to reply you late. In regard to your problem, please try to re-upgrade the firmware. Please press and hold the Power Button for 5 seconds when the Tello is powered off and release it when the green indicator turns off. Then the indicator will pulse red. Connect to the Tello's Wi-Fi and go to Setting - more - firmware version to upgrade the firmware again. After that, please confirm if the issue still persists.
If the issue still persists, please contact us via support@ryzerobotics.com.
I hope my answer can help you. Thanks a lot.

Resetting Tello works mostly in such cases. Keep power button pressed for 5 secs.

I had the same problem. Drone was showing sensor error and was not calibrating. I contacted support but they only told me they did only told me to bring it back to repair.
I found a solution by myself which is really simple: just reset the drone. Power on, press the power button for 8 seconds, reinstall the app and everything gets back to normal. Hope this works for you too.
