My girl has the Stylo for Boost and has had the update notification for a while but just ignored it because she doesn't care / is a picture nut with no space left on her phone. Recently I realized out of surprise that it's actually marshmallow that was awaiting and urged her to install it. She barley made the space by a few MB but nonetheless did and downloaded the update. I hit restart and install and the phone then rebooted as if it had nothing to install and nothing happened. Software version still says 5.1.1 and now the update LG software says everything is up to date. The hell? What is going on here. Where did it go lol? The only thing I can think of is to factory reset so it'll come back but that's like against her religion she won't do it......or to call boost and see if they could push it again. Idk what happened in the first place though. I've never experienced something like this lol.
