Problems after returning stock

So I have a Verizon lg g4 and I did recently rooted my phone and decided to go back stock. Upon doing that my phone no longer boots normally, like if I just try to turn it on the screen stays dark and doesn't boot up but if I pull the battery and hold the power button for a few seconds and then wait 10 minutes and put the battery back in it has a better chance of booting back up. Also when it does decide to boot up I have absolutely no sound except for when I make calls or use a Bluetooth speaker. Any ideas or suggestions? Either way Im getting a replacement Wednesday
