My HTC Incredible (Verizon) has tried to update to
either Ice Cream Sandwich (android 4.0.x) or just build # 4.x (I'm not sure which) for the past two weeks or so. Either way, it has not been succesful.
Sometimes I'll get a notification telling me that the update has been downloaded, and asks me whether I wan't to reboot to install. I tried that a bunch of times, but neither time did it even shut down after the ten second delay/grace period. Once I tried going to Settings > About Phone > System updates, and downloaded the update and tried to install, but the same thing happened: ten second countdown, then nothing.
Now, the notification never pops up, and Settings > About Phone > System updates indicates that no new updates are out. What's happening?
