So the Windows Phone 8.1 update for both these phones started rolling out over the air to Sprint customers in the first week of December and based on looking through various forums it looks like the roll-out completed to all Sprint customers in the 3rd or 4th week. Based on comments in https://help.ting.com/entries/104181733-HTC-8XT-8-1-Update and https://help.ting.com/entries/104160043-Sprint-rolled-out-the-windows-phone-8-1-update-to-the-ativ-s-neo-this-week-When-will-we-get-it- it doesn't appear that any Ting customers have received the update yet. Since it's been several weeks since the rollout completed on Sprint so I don't think we're going to as it stands.
After a lot of searching through various forums it appears that there were some issues for certain Sprint customers in receiving the update (no updates then they fix the issue and get it immediately) when they had modified their default device (through the 8.1 preview or other methods https://help.ting.com/entries/93176696-ATIV-S-Neo-voice-roaming-currently-unsupported-on-version-8-0 ) in order to work around issues Windows Phone 8 has on the Sprint network.
Some users were able to get the update over the air when they had the 8.1 preview installed and others weren't. The single commonality among the people who don't receive the update, both with the 8.1 preview and other methods, seems to be that Settings->Cellular shows no active network. All Ting users with Windows Phone 8 share this issue even with default devices.
I think not getting the update and no seeing an active network in Settings-Cellular share a common cause, likely meaning Ting needs to do something or get Sprint to do something in order for us to get the 8.1 update over the air. I really need the 8.1 update soon because I need an app only available to 8.1. Is there a way for me to work out this issue myself? Maybe I can go to a Sprint store and borrow a SIM card long enough to get the update? Has anyone found a way (hack) to get an active network showing? Is there a Sprint 8.1 ROM floating around somewhere I can download rather than having to bother trying to get an over-the-air update?
I'd really rather not install the 8.1 preview because reasons https://help.ting.com/entries/102768596--Warning-Windows-Phone-8-1-Developer-Preview-and-Ting
Thanks for any help you can provide.
