I fixed my iPhone and wasn’t able to get some screws unscrewed over the battery so I left it plugged, same thing with the logic board, there was one screw left so I just rotated it in the process, I wonder if I damaged it
Better you can show it to a technician who repairs phones, so he can see whats goone wrong
Hopefully you turned the phone off before doing any repairs. If you left the battery plugged in while unplugging other components, you could have shorted something out. Power always needs to be disconnected for that exact reason. What exactly did you fix on it and was the phone off before you took it apart?
