Took a few tries, but upgrade finally took, can say the Playstore works but Kodi remained at 14.1. Not a deal breaker!! Did have to re-format the SD card completely before it applied the update properly.
Box went thru the motions but never updated until I reformatted the SD card and did it again. Just a heads up if anyone else is having the same issue.
Will go thru the rest when I have time and if anything pops up I'll report in!!
