Hi again, I received excellent advice here when I had questions about the Phantom that I purchased for my hubby's birthday last year. I'm back with questions about the Phantom 3, he's getting for our 30th anniversary. I charged both batteries then updated the helicopter with no issues with update 1.2.8. I checked the .txt msg which told me I was successful but that gave me false confidence. Then I tried the controller. The battery was charged, it was turned off and I put the card reader in with the disk that had the update on it. I clicked the power on switch, the LED lights came on briefly and then nothing. I waited the 60 secs, then another and another. Nothing happened. I left it for about 15 minutes and when I got back, there were no blue lights or anything indicating it was on. I even copied the firmware file to a thumb drive and tried with the same results. I thought that maybe the battery hadn't charged after all so hooked it up to the charger and the LED lights came on indicating it was charging. After the lights went out, I tried the update again and nothing happened other than the LED lights briefly flashing. No blue lights or blinking lights... Nothing. The controller will flash the LED lights once and only once after it's unplugged from the charger. That's it. No other lights indicating it's on or off so I'm not sure if it is on... or off. What am I doing wrong?
