Alright, so I tried to install the windows 7.8 update via Zune and it kept saying my phone was up to date, I tried the disconnect trick also and that didn't work. Me being me, the impatient one, I tried to use third-party software to do it, it was working and then it seemed like it froze, I waited five minutes and nothing changed. So I unplugged the phone to turn it on and now it's bricked, I think. I'm un sure as to address it in the correct term. But it keeps coming up with the picture on it saying not to disconnect it from the PC. OR, when I hold down the power button and release it, it vibrates. Every 5 minutes it vibrates by itself.

 

Also, I've tried a hard AND soft reset and nothing's worked. I don't know what to do.
