Been trying for some time, kind of just left it at that. But my phone refuses to see the new update.  I'm stuck on 4.3 right now. I've tried hard resets and the checkin code that was talked about in the previous thread about people not getting the 4.3 update.

Anytime I go to the software update screen. The window will pop up saying it's checking for the update, then after 5-10 seconds it'll just go away and nothing happens.

The only time I can get at least a response message (one stating there was some error and to retry) is when I use the *#*#checkin#*#* method and change the date a year forward, like what was directed to.
