Power passed to MacBook air through USB port
In an attempt to upgrade firmware to one of my GoPro gimbal, I connected with batteries to USB port and switched on the gimbal, MBA went off immediately and never started. What can go wrong or how to restore?

Post a couple of High-Res images of your logic board with your question. It sounds to me like you overloaded the USB circuitry and may hopefully just blown up a few components.
