I have a Tello that turns on, 1 green light, then 4 red flashes and then stops working. Only way to continue is to remove the battery and start again. I have tried different batteries - same thing.

Turn the TELLO on until its flashing yellow rapidly, then press and hold the power button for 5-8s until the led goes off, then reconnect after it auto rebooting.

The Tello doesn’t get that far. Only 4 red flashes and then essentially shuts down.

Hello. I'm having the same problem. Have you find a solution?

Can you elaborate more on when this occurs?

Four red flashes followed by a shutdown would (typically) indicate the Tello was overheated.

Got the solution... At least it worked out fine for me.

I contacted the Ryze Robotic Support. That light sequence: 1 green followed by 4 (or 5) quick red flashes indicates that the Tello needs to update its firmware. The instructions they gave were these:

-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 update the firmware again by using the Tello app. Check whether the issue is resolved.

I followed those instructions and my Tello is back to life.

I hope it works for you too.

Greetings from Colombia.
