Hmm, not sure what's going on then. The emulator is still running maybe?I disabled Amazon Games. And even though Play Store is on the Fire now I am not sure it works. I haven't set up wifi for fear of an update!. I did disable OTA updates though so I'm sure it's safe to turn wifi on now.
As for OTAs as long as you've disabled it in the Modify System Settings tool then you should be safe to hook the tablet up to WiFi. Just be careful, if the Toolbox isn't working properly it may have not disabled OTAs correctly.
I got to go to bed my friend. So tired. Catch up with you tomorrow if that's cool with you.
