Impossible to put the drone on bind mode and to connect to controller

Hello, I have several problems
I bought a meteor65 with the 2SE literadio and it’s
Impossible to put the drone on bind mode.

When I connect it to betaflight I can not put CLI, I installed all the drivers, tried to put .hex files but it marks that I can not put files larger than 32kb while they are 400kb.

I cannot connect the remote control to the drone

When I connect the goggles it marks that the voltage of the drone is at 0 and nothing is working.

I hope someone can help me, thank you

Which version did you buy? i.e. what RX does it have installed?
