A7105 not able to bind with flysky - eachine 010s

Hi all

I new to flying RC so bear with me.

I have recently purchased eachine 010s that has A7105 transceiver. I think it did bind initially, side green LED's would react to controller movement but I wasn't able to arm the drone. I have connected it to cleanflight no problems but then I have decided to connect a battery at the same time which I believe cause issues I'm having now. Binding LED instead of being blue.

Is there are way of checking whether a7105 got damaged?

IT probably didn't arm because you didn't set the ARM switch correctly or the throttle range in Betaflight.
