My drone used to connect when ever it was plugged in via USB or battery. Now when I power it on the tx won't connect to it. The green Rx light stays on as if it was bind. I tried the plug in 3 times to put it into bind mode with no luck. I tried to reflash the Rx but wifi will not show up anymore.

have you tried putting the reciver into booloader state and trying flashing it via passtrough?

There should be a boot button i think

There is only 1 button and it's for the flight controller

#

#

I tried the boot button again then installed the impulse RC driver fixer. Then unplug and replug the USB and now it's recognizing it

#

Thanks a bunch

🔥🔥🔥🔥🔥🔥🔥

#

Ok update. I unplugged the flight controller from betaflight and it got stuck again

@sage sage , is this solved? that button is shared for both FC and elrs

#

you press button then connect usb, go to betaflight -> flashfirmware tab, there should be a button to exit DFU

#

click on it till it becomes grey

#

now, open elrs configurator to flash
