Samsung Galaxy S6 getting stuck on the Samsung logo when starting

[AC Question]

So I rebooted my phone earlier as I a had a situation where I needed to re-root my phone using SuperSU. But when the phone restarted, I was met with the screen saying 'Samsung' with blue sparks coming from the logo. It would be stuck on this screen infinitely. I have tried the technique to restart using the Power+Volume Down technique but it still gets stuck on this same screen. Anybody have aj other idea on how to fix this?
