You need to connect the wifi while downloading the firmware then you need to connect the tello's wifi to install it and upgrade its firmware
Thanks.
I just contacted the RYZE support via the chat service. He failed to solve my problem and sent my problem to the development department of "Tello".
My phone IS connected to the internet with my WIFI Box, but I have the message: Failed to download the firmware.
