Title says it all. I've gotten the message saying a software update was available, and I initially cancelled because I was on 4g and couldn't get to WiFi. WHen I was on Wifi, I got it again, and I clicked "install" this time, but nothing happened. I can't get into the "System Update" screen for some reason, and Motorola Device Manger won't update my phone software, or even show me my current software version ("Current version: N/A"). I've restarted many times, but I have no idea what to do anymore. I've fiddled with USB debugging, reinstalled device manager several times, etc etc etc. Can anyone help me?
