No Software updates available for HTC One M9 on Android 5.0
I'm stuck. In order to upgrade from 5.0 to 6.0, my phone should have firmware version 3.38.502.31. My phone still has firmware version 1.32.502.31. I've checked for updates to bring it up to the current version, and there aren't any available to download. What are my options? It seems strange that AT&T has numerous updates for the HTC One M9 since April 2015, and none are avaible for download on my phone. See photos below of current phone software version. All help is appreciated. I'm not sure if I should just bring it in to a store, which is a pain. Thanks.
