This article goes into more detail about how these new measures will actually work compared to the blog post earlier this year from Google. Namely:
- Enabling the OEM unlocking setting will no longer prevent FRP from activating.
- Bypassing the setup wizard will no longer deactivate FRP. FRP restrictions will apply until you verify ownership of the device by signing in.
- Adding a new Google account is blocked.
- Setting a lock screen PIN or password is blocked.
- Installing new apps is blocked.
This assumes everything works fine. It’s probably an edge case, but on my Nexus 6P an update somehow messed with my encryption keys, and the screen lock pattern that I’d used for over a year stopped getting recognised. I can’t remember the solution but I vaguely remember having to factory reset. Whatever the solution was, it wasn’t too different to what a thief would do… I was bypassing the screen lock after all.
