No Lights and Constant Beeping at Startup (Phantom 4)

[Callum Bondy]

When I was updating my firmware, the cable connecting my phone to the phantom popped out. Now when I turn on my phantom, I get a constant beeping and a green to red flashing light above the sd card slot. The leds on the arms do not turn on as well. Does anyone have any idea on how to fix my Phantom 4

Try installing the firmware again. If needed, you can find detailed firmware installation instructions here.
