Woke up this morning to a Note acting very strange...

All i kept getting was "Google Play has stopped responding" constantly, so i reverted it back to it's factory state(the app) and it seemed to fix it.

Now, my phone refuses to boot. I'm not sure what's happened, as i've been sleeping, but nothing like this has happened before!

In the last few days, i used PA(latest) and then flashed stock again with Odin, which I'm trying to do again now, and It's hanging on SetupConnection.

Does anyone have any ideas of what to do?

Thanks :)
