1-It does not update. It is always changing between "downloading" and "waiting to download"
2-The usb does not work. It does not read the usb with my files, and if I format it as internal storage, my computer does not recognize it to re-copy my videos inside
EDIT: ExFat works, it is recognized by both my computer and the Mi Box. So problem 2 fixed
Make sure the USB is formatted to Ex-FAT or FAT32. Insert USB, power up MiBox, should be readable by Kodi or VLC.
