Re: why I can't update

You will have to be physically in US connecting to AT&T network with an AT&T sim card in order to receive OTA update for this phone. There is a Lollipop ROM for this phone floating around the Internet. Xda has a thread about it. You will have to download the ROM file and manually flash it using ODIN.
