okay, so basically today was my first time flying my p3 advanced. After some flying i landed on an uneven surface, resulting in it tipping over, and 2 props being stuck in mud. I cut the engine and set it up to fly again. However, upon startup, only 2 engines fired, and only for a fraction of a second (these were the engines that didnt get stuck in the mud). i then brought it back home to recharge the battery etc. After the battereis were recharged i notice that it needed a firmware update so i proceeded to download that. I then removed the props (because the drone was indoors) and turned it back on. It showed red lights on 2 of the legs and then fast, blinking yellow ones on the other two. On my phone (galaxy s7) it showed that there was no controller signal and a video connection could not be made to the drone.
