A while back I had a crash that serverly damaged a battery as well as a motor and when I got home to try to turn it on despite these damages it was all functional but couldn't fly of course, anyways I ordered a new motor and when I installed it the flight controller wasn't getting voltage and the escs wouldn't start up so I decided to get a new flight controller but again it wouldn't light up. So now I assumed it was the 4in1 so I purchased a new 4in1 ESC and installed it all and now I've run into the problem I have now would love any help on this because I've been stuck at a roadblock for a while.

Here is the quad atm - Image

This is what I'm dealing with it's my second ever drone currently the VTX and camera aren't attached but both work perfectly fine when powered, also the motor cables to the esc isn't connected from previous troubleshooting.

Aha I just noticed your motors are not soldered to the escs, you won't here beeps until motors are connected.

yeah I know, the reason they aren't soldered is due to me trying to trouble shoot, I've tried with them all soldered and still nothing. Will the sec start up if any of the motors are defective? b
 
You got to have at least one motor soldered to hear the start up beeps. The sound actually comes from the motors.
