Hello, I recently purchased a dji phantom 2, took it out for one flight and everything worked fine. After that I re-calibrated the transmitter, and set it to mode 2. Before I went to fly it again I fully charged the transmitter and quadcopter batteries. Upon turning it on it flashed the usual self test with all the colors flashing. The in beeps with the red lights flashing and all four props briefly twitch. After that the lights flash off there is a pause and 6 red LED lights come on and stay on. The motors cannot be turned on. I hooked up to the computer and the run the assistant. I get a little caution symbol flashing the bottom right corner, I clicked on that but nothing happens. I cannot see where there is any other indication that something is wrong. What is wrong? Sorry if this has come up before. I attempted to search the forum and internet, but was unable to find anything helpful.
