Help Needed Updating 4.4.2 to 4.4.4

[Deleted User]

Hello everyone! I'm looking to update my phone to enable VoLTE due to network upgrades, I need to update from Android 4.4.2 to Android 4.4.4...specs below:

Samsung Galaxy S5 Active
AT&T Branded
Unlocked/Unrooted
T-Mobile Network - United States
SM-G870A
Android Version: 4.4.2
AP: G870AUCU1ANG3
CP: G870AUCU1ANG3
CSC: G870AATT1ANG3

I've tried OTA update and Smart Switch to no avail due to age/branding, no luck with Android Kies for Samsung either as the software seemed buggy. I've scoured the web raw looking for an update download with no luck.....not being a huge fan of newer phones I'd greatly appreciate assistance bumping mine up a notch to enable VoLTE.

Thanks in advance!

Although the phone is carrier unlocked from AT&T the firmware is still issued by them and you will need to be on their network to update it as it is issued by them.

I'd imagine rooting is the only option for changing the OS...unless AT&T felt exceptionally helpful and generous after having them in the past.

As per my previous link, rooting the AT&T model is not an option, thanks to their mega locked down bootloader.

even if you were to upgrade to android 4.4 your phone will not be compatible with volte as it is a carrier thing to allow volte. i think some models might have volte working but it will depend on your carrier....you can't just make it happen.

sorry but it is not that easy.

Plus many carriers are offering free comparable phone's to upgrade to. I know you said you hate new phones, but such is the life of technology. Now's a good time to upgrade your phone.
