any one use "DroneBlocks" to any avail? the app did not work so well for me. I also think it contaminated my firmware, as tello no longer holds position and altitude. Is there a way to reboot and reinstall the firmware on the tello? Thanks
You can do this. Follow 3 steps for reset your Tello firmware:
1.In the tello aircraft press and hold by 6 seconds the "power button" until LED indicator turns into steady RED color.
2. Open the tello app and connect your drone.
3. Go to settings and update your drone to the latest firmware.
