Think you're still in with a chance, I only got my 10 update about a month ago, one of my Sons only got his update a week ago and the other is still on 9...we're all in the UK.Love mine of all the android phones I've used which included ZTE, Samsung, Pixel. Only wished it was able to get updates as I'm in the USA using an unlock version, but still running version 9.0.0
Finally succumbed and updated to EMUI 10. Too early to make any judgments.
That it ain't.
