A new to me Phantom 3 Standard, hasn't been used in over 3 years, and battery lights would not power on. I got a replacement, same specs, it came with 3 lights on, I charged for an hour and now has all 4 LEDs. I popped it in, turned on, and I get this in the app. Also, this IMU won't calibrate and is stuck on 1%, please advise, thanks...
