So I have received my Inspire 2 back from DJI Repair Center, It did not crash nothing of this sort, the battery button was stuck and has to be fixed. Now whoever did take it apart did very bad job because now all I'm getting upon startup is ''Navigation System Error - Check Redudancy State'' with Solid red LED and will not launch so it's obviously very bad error, I see that lot of people has had this problem before, any fix for it or I have to send it back to DJI for ANOTHER 3 weeks.
