My Location: United States - Central Time Zone, Cricket (an AT&T mvno)
My Device: Lumia 1520, RM-938_lta_lta_905, Mobile Operator 000-22. This device has never been off official. No Preview for Developers, no Insider Preview. (I love my Beast Phone[SUP]TM[/SUP] way too much to to fiddle with that stuff on here. That's why God invented backup phones.)
I backed up yesterday and nothing has really changed as I've been driving a 640 on Insider Release ring for the past few weeks.
Backup servers appear BUSY as I kept stalling at 16%. Imma go with yesterday's backup.
Could not find Upgrade Advisor with a store search. Luckily I had it earlier and uninstalled it. Found it on "my apps" list and reinstalled. Ran the Upgrade Advisor. It found an Upgrade to Windows 10 immediately.
I have autoinstall for updates turned off. On to Settings > update > update is waiting (I also got a toast notification). Downloading/Installing W10M now...
