Do you have any leftover root-related folders? Ingress (like PoGo) scans your internal storage for anything that's root related - Xposed, Magisk, SuperSU, su, Busybox. Doesn't matter if you're not actually rooted. Also uninstall any similar root related apps.

Didn't work for me.  Still says my device configuration is not supported.  Guess no ingress for me.

FIX: If you are getting this error on an unrooted device make sure you have all root tools uninstalled as well. Removing an old copy of SuperSU that was backed up to my new phone worked a charm.
