Hey everyone! So my co-worker here has the AT&T HTC One. He is in the IT department with me (so he has no excuse ) and knows zero about updating his phone. As I was installing KitKat on my OneMax I asked him about his OS version. We discovered he was on 4.1.2 and is unable to pull any updates from phone. He did some preliminary searching and discovered this was a known issue. Looks like info he found said using the RUU is the only way to get current?? Did some quick searching and didn't see anything. Trying to get him to sign up here , but will at least point him to this thread. Links to thread about this? Or some simple RUU installation instructions for him would be greatly appreciated. Thanks!!
