Yesterday my Phantom 2 Remote Control(DJ6) stopped working during firmware update. I was doing the update, it turned off my remote control, said to power cycle, but when I tried turning it back on nothing happened. Even if I have full batteries, it WON'T turn on. Is the remote control fried? I go into the RC assistant software, but it can't do anything because remote won't turn on. Any suggestions? Or do I just need to buy a used remote?
