So I have an htc one m8 that I bought in October of 2014. It is running at 4.4.2, and every time I check for an update it says there is no update available, although I know lollipop has been out for months. Btw my carrier is at&t. I went into the AT&T store and asked them about this and they just told me that the update will come over time. Since I got my phone, It has never updated. I tried that thing where you manually install the update using htc sync manager. That didn't work either.. Any help?
