Guide how to write on external ntfs usb drives for kodi on android 6.0.1 no root

Hey so this took me about 3 days to figure out seeing that I got the mi box mzd-16-ab and there’s really no way to root it so I thought I was out of luck getting kodi to write files to it, but I figured it out, and idk if it’s been cleared or so but I couldn’t find anything on it at all. Any way just let me know if some of you want the guide or if it’s useless because there might be one already . If you guys wanted I will type it up later on tonight. Also I might be able to allow write on nfs and smb this way which could be good with Amazon Fire TV I can’t try though since I ended up returning mine.
