Why is my phone on a "Android is starting... *loop symbol* Starting Apps after I updated it?

My phone recieved a notification about a new update, and without reading because like an ***** I felt no need to mistrust an update, I accepted and now my phone is on a loop.

So I accepted the update, my phone restarted or rebooted and came to "Optimizing Apps # of #", after it reached the certain amount of apps it came to "Android is starting... *loop circle symbol" Starting apps."

It has been two days now.
I rebooted it. Multiple times.
Factory reset. Multiple times.
Clear cache. Multiple times.
I thought oh maybe it's because it's not connected and charging... nope was not it either.

I have let it since sit in the same state for 7 hours.... it's currently 4:37 am.

Please if someone can help without the same procedures I have tried multiple times. I really need this phone back up and running.

I have looked and searched but I have not come across anyone else with this specific and to the last detail problem that I am having right now.
