Guys! I have big trouble, I think. I made a mistake! I wanted to update my firmwire on st16 and maybe drone. On my drone I haven't done yet, but have done it on St16 . I just confuse with other model that looks the same from official site and download it. When I set up it on ST16 I also set up program data pilot for making routes and update everything again after it asked me. So, now my droid firmwire became version : 4.4..4 but I can can't use data pilot on my drone (I think, because it doesn't connect) and also I can't return my last android version! I tryed to do reset and rebuild, but aster that works only tablet mode, but no fuctions available or drone control! What I need to do? And how to get back my android version and all functions? Thanks who will help! ^( If you will need more info - just ask me!
