Controller won't power up

[Kj47si]

think I screwed up my controller by factory resetting it. Won't power up now. Did I just screw this up? Couldn't get preflight update to complete so I tried to restart the process by resetting the controller. Any help will be appreciated

Pull the battery on the controller , reinstall and try again. Make sure you are using a charged battery.
Also heard that sometimes the SD card in the controller can work loose from shipping. If you still don't have any luck try and open the controller and reseat the card.
