Thanks, roger, got it. Pro root works on non-pro. That's the link above and in the pro thread , mate_9_pro_root.zip, but adapted for both models.

I am getting an updater error with the new pro superuser (multiple attempts in new recovery new recovery. . No full root. Recovery does come up with updated rayglobe ver number. 3.0.3-rayglobe
even when going back to 126.96.36.199 and reinstalling super user zip.
Superuser 2.0 Beta 9.apk installs after uninstalling older apk, but it doesn't mater with the Updater error on the zip install
Updater process ended with ERROR: ! Error installing zip file
I can release a boot.img already full patched (also with chianfire supersu) also for mate 9 users but I don't want spam in this thread. I've a lot of respect for author so seldom I reply here
