Thanks Lon for getting back with me. I have a windows 10 computer BUT my internet connection is NOT the best too say the least, BUT if I am the only person on and do not have a ton of pages open I do manage. I live up in the mountains of western North Carolina and a bit out of town which means there is not to much infrastructure been installed out our way. BUT that being said I have had ALL the updates prior too this one that have had NO issues and used the controller to do the updates VIA WIFI and all went well. This is the FIRST firmware that I have had an issue. I did as you have written, have the latest assistant 2,and as well used the same cable that came with the controller,(same one I charge with) and 4th, data reset the controller. NOT quite sure what you are referring too with this statement, can you give me more advice as too what you mean by that ? NOT quite sure about just what and how to reset the controller, do you mean to reboot the controller? Again appreciate your time and patience, with my lack of knowledge. Lon, do you feel even with my slow internet connection the firmware should still work? I do get it too download but as I had mentioned in my previous post It never updated. Oh yeah Lon, about USB 2.0 do you feel that is an Issue,? I have been using 3.0 also what's this about an SD card, I had NO idea there is an SD card in or on the controller, only SD card I have is in the Drone. I think I will TRY to connect VIA back of the computer as you suggest for my usb connection. Thanks again for your time and sharing knowledge, keep your fingers crossed. Bill
