I've had my P2 since the beginning of January '14 and never had any problems with it. Lately I experienced some problem with the video preview link between the P2 and my iphone so I had the bad idea to upgrade the firmware to see if the problem could be solved. Trying to upgrade the RC something went wrong during the procedure popping an error window on my computer. Now the RC doesent even start, when i plug the usb the rc sw doesen't see it so I can't try to redo the upgrade procedure. The same happened on the phantom, error during the upgrade and now when i turn it on it keep beeping and the software don't see the phantom connected even if the usp is correctly plugged in. So.. RC and P2 completed bricked. Does anyone have a solution for this embarassing DJI fail? thanks!
