My Phantom 3 doesn't want to upgrade, it is still on 1.1.9. I downloaded the firmware bin put the bin file directly on the root of the sd card, put the sd card in the phantom, turned the phantom on. It does its normal startup routine, front goes red back flash yellow but no system board beeping indicating an update in progress ? If i take the same exact micro sd card, put it in a micro sd -> usb and put it in the controller, the controller updates fine from the same file on the same card. Ideas ?
