First, just click install when notification pop up. Then when the pls wait sign shown up, restart your phone. After restart, it will say update fail and ask u wheather want to report the error or not. Just click cancel. Voila....both notification and logo gone now. Remember unchecked the auto update in setting to prevent same scenario reoccur... 
Just go to about phone in setting and check for update. Then u should able to get the update again.

Have you uncheck the auto-update in setting->about device->software update->auto update?
