Nothing after apple logo
Very new to this, so please bear with me.
Yesterday morning I woke up to my phones screen completely smashed. I'm not entirely certain what happened, but it was pretty bad. I have a 6S plus (16GB). My first thought was to just get a screen replacement, but after trying to boot my phone up, I realized that no matter what I do, it will only display the Apple Logo with the pretty white screen and then nothing, the screen is visibly lit (I can sorta see the backlight) after the logo disappears, and it'll just sit there (I've tested if for about an hour.) and just let it sit.
I've been googling for the better part of a day trying to discern if it's even worth trying to get this phone fixed, it seems like a lost cause. As of now, I've attempted to reboot it using itunes, allowed it to sit on a charger for about an hour: powered off, let it sit powered off all night and even attempted a total factory reset using itunes. None of this has made a difference.
Please help!
