Crashed my Phantom 4 Pro but came across a Phantom 3. Am unable to link the Phantom 3 to the Phantom 4 controller. Followed procedures and repeated multiple times to no avail. Controller looks fine (blue light blinking, app does the countdown, etc). Pressing the link button for two seconds, light is red. Tried both with and without a cable between the two.
Any ideas? Thanks!
