Hey, i've followed the guide on downgrading.. but when I selected slideshow after highlighting on the photo icon, my screen just keeps loading and no colors appear. Its just a blank white screen with the loading icon at the bottom irght of the screen. I'm still able to adjust my volume, but my other buttons doesn't work when my screen's still loading. I've waited for like 10-15 mins but theres still no progress during the load. Could someone help me with this?
