1 - When turning on the 770 (booting up) it seems the progress bar gets about 1/8 of the way then resets (the screen blinks) and starts at zero again. It then gets to about a 1/3 of the way and stops (but the 770 looks like it is continuing to boot up) then a few seconds later the home screen appears.

Mine does the same thing but does go a little farther after the first reset (screen blinks), maybe to 8/10 then home screen.
