The big question is if the reboot problem is fixed? My wife's 1020 never rebooted and once she updated to Cyan and 8.1, it's happens a lot. Daily or more frequent. I just turned off her WIFI (as I think she really never had WIFI on before) and we'll see how that goes. She does have Glance on, too, but she has always had Glance, even under 8.0.
Next step is to use recovery tool to reinstall 8.0 possibly leave it there for a while. If I do that, will the recovery tool also revert back to Black firmware, or is Cyan on the phone for good now?
